Look for a treadmill motor that fits your needs. Rated DC voltage, rated speed, and rated current are all characteristics of treadmill motors. In that order of significance, the ideal motor has a high voltage, low speed, and high current. For voltage/speed selection, a rule of thumb is that the ratio of speed to voltage should be less than 20. Subtract the voltage from the speed. This is the motor speed that produces 1 volt. At 300rpm, the motor will generate 15V at a ratio of 20. Because this is near the lower limit for battery charging, a lower ratio or a faster-turning wind turbine is required. After calculating the voltage, multiply the rated current by the voltage to get the power.
Is it possible to use treadmill motors in wind turbines?
Treadmill motors are useful for tiny wind generators because they are durable, readily available, and reasonably priced when purchased used. They are permanent magnet motors, which means that when they are spun, they act as generators, producing direct current that may be used to charge batteries. These motors are often rated at several thousand rpm and have more than one horsepower. Small wind generators usually spin at a maximum speed of several hundred rpm, resulting in a power output of 200 to 300 watts.
What is the maximum power that a treadmill motor can produce?
However, there is a scale issue. The treadmill’s maximum output per hour is 200 watts. On a daily basis, the average American consumes roughly 28,000 watt-hours. With an electricity cost of $0.12 per kilowatt-hour and the power that would have been used by a motorized equipment, the maximal treadmill workout, generating 200 watts for an hour, would save 2.4 cents.
The bikes and elliptical trainers sold by the company may provide up to 250 watts of power. A 147-pound person running 8:20 miles on the treadmill would only produce 24 watts every 30 minutes, or enough for 4 hours of Wi-Fi. A 176-pound person jogging for 20 minutes could light a 60-watt lightbulb long enough to keep the room lit while they work out.
What is the wattage of a treadmill motor?
What is the average amount of electricity used by a treadmill? I couldn’t find a conclusive solution to this question that was supported by data. To discover out, I did some study and testing. Here are the outcomes.
The average electric treadmill has a motor that produces 2 horsepower (1,500 watts). When following the recommended standards for moderate-intensity workouts, you should anticipate to use around.7kWh of electricity per week. In the United States, this equates to about 10 cents per week in power, $5.10 per year, or 43 cents per month on average.
If you conduct high-intensity workouts, you can expect to use less electricity. This is due to the fact that these workouts are usually shorter.
The most popular electric treadmills have a power range of 1 horsepower (746 watts) to 3.75 horsepower (2,798W). The most frequent motor in our list of popular treadmills is 2.25 HP (1,679W), with the most popular treadmill sold having a horsepower of 2.6 HP (1,940W).

Is it possible to utilize any engine for a wind turbine?
The motor you use is, without a doubt, the most critical component of your wind power generator. If you’re new to small wind turbine construction, you’ll find this to be one of the most perplexing (and contentious) components of the process. Oh, the motors, generators, and alternators! There are a number of words that appear to be referring to the same thing.
Many industrial motors create excellent wind generators at a low cost. The motor is used to generate power in a wind turbine. The “motor” would no longer be referred to as a “motor,” but rather as a “generator or “alternator.” This article focuses on possible motors that can be found as surplus items on the internet and utilized to make your own custom wind generator.
Obviously, selecting the right motor for your generator is critical. If you pick the wrong one, you can find out that:
- There will be no electricity generated by your wind generator.
- Your wind generator will generate electricity, but not at a high enough voltage to generate usable electricity.
- Your wind generator will initially work, but it will overheat and quit working within a few days or weeks.
Don’t get discouraged, though. There are hundreds of motors that can create hundreds, if not thousands, of Watts of useful energy. Even better, we’ll give you some pointers on how to find one at a fair price.
Generators generate electricity in one of three ways: by induction, an exciter, or PERMANENT MAGNETS.
Magnets, Magnets, Magnets!
Permanent Magnet Motors are almost entirely used by do-it-yourselfers to make wind power generators since they are widely available, dependable due to their construction, and can generate electricity at virtually any RPM. Other sorts of motors, on the other hand, cannot be regarded to be in the same category.
A coiled copper coil is surrounded by permanent magnets within a permanent magnet motor. Electromagnetic induction drives these motors, which means power is fed into a coil of copper wire, which generates a magnetic field. The permanent magnets in the motor casing are at odds with the magnetic field formed by the energy flowing through the copper wire. As a result, the copper wire connecting to the motor’s shaft attempts to “push itself away from the permanent magnets.” As a result, your motor begins to spin!
When considering a permanent magnet motor as a generator, the same logic applies. The voltage difference between the two ends of the copper wire is created by spinning it with the wind’s energy in the presence of the magnets. Electric charges (electrons) flow in the copper wire as a result of the voltage differential, generating electric current.
Volts-to-RPM Ratio
One of the most significant criteria to check for when choosing a motor is the Volts-to-RPM Ratio. Because of their low cost and broad availability, most DIYers utilize their motor to charge a 12-Volt battery. To charge a 12-volt battery, the permanent magnet motor must produce at least 12 volts. If it doesn’t, it won’t be able to overcome the 12V battery’s impedance, and the motor will never charge the battery. How can you determine if your wind-powered motor is capable of producing more than 12 volts? Continue reading.
A permanent magnet motor’s volts-to-RPM ratio is defined as the number of volts necessary to spin the motor at a particular RPM (rotations per minute). Assume you have a permanent magnet motor with the following specifications on the label: “2500 RPM at 100 volts. Simply said, if you feed 100 volts to the motor, it will spin at 2500 rpm. It has a volts-to-RPM ratio of 0.040. (100 divide by 2500).
This figure gives an approximate idea of how many volts the motor will produce at a certain speed. Let’s pretend our 2500 rpm, 100 volt motor is rotating at 450 rpm. At what rpm will it create how much voltage? Here’s how to figure it out:
There’s one more thing to do now. 18 Volts must be multiplied by 80%. Why? Because the number 18 Volts only applies if the motor is being used as a motor. This motor isn’t being used to move anything. It’s being utilized as a generator, and it’s not 100% efficient. As a generator, it is approximately 80% to 85% efficient.
At 450 rpm, we know how many volts our motor will produce: 14.4 volts. The realistic RPMs of a wind generator must then be considered. Most likely, you’re constructing a “Small wind generator with a power output of 100-500 watts. When the motor is under load (meaning the motor is attached to your battery bank), any well-constructed 50-to-60 inch diameter blades on that motor will easily produce 450 rpm in wind speeds of 8-10 mph. When a generator is under load, it has to work harder, which causes it to spin a little slower than when it is not. In wind speeds of 8-10 mph, this motor will start charging a 12V battery bank.
This is in line with your goals, thus we can deduce that this permanent magnet motor would be suitable for use in a wind generator.
When looking for a permanent magnet motor, a voltage-to-RPM ratio of AT LEAST 0.035 is the minimum need. It’s perfect if the value is more than 0.035. If the value is less than 0.035, it will most likely be insufficient unless it is in a windy environment.
Amperage Rating
The motor’s amperage rating is the next item to consider. This tells you how much current the motor will generate when used as a generator. According to our experience, predicting the type of current your motor will generate as a generator is quite challenging. We’ve encountered motors that produce more amps than they’re rated for. One thing is certain: the higher the amperage rating, the better. A motor with a minimum amperage rating of at least 5 Amps is what you should be looking for. You’re good to go if the current is greater than 5 Amps.
The power generated by a wind generator is proportional to the amps and voltage:
Keep in mind that the more amps and volts the wind generator generates, the more electricity it generates!
So keep these three key considerations in mind:
Because we want to keep things simple and straightforward, we’ve skipped over some topics in this essay. This information, however, is all you’ll need to look for a wind generator motor with confidence.

What is the voltage of a treadmill motor?
Metal cutting mills and lathes, drill presses, bandsaws, sanders, and other power equipment may demand.
Motors ranging from 5 to 2 horsepower with the ability to fine-tune the speed while preserving torque.
Most treadmills, by coincidence, employ an 80-260 VDC motor with an appropriate HP rating and a PWM motor speed controller to allow the user to vary the belt speed while running and maintain a decent constant speed and torque.
Commercial DC Motor/PWM controllers are available, or you may construct your own PWM circuit and buy all the components separately, but either way you’ll spend a lot of time and money. On the treadmill, you’ll find all of the necessary components.
Safety and Disclaimers- You should have a basic understanding of electricity and the dangers of home current, as well as an understanding of your own talents and limitations.

Is it possible to utilize a car alternator as a wind generator?
If you’re new to the idea of making a wind generator out of repurposed parts, you’ve undoubtedly asked yourself a few questions like these:
- Why are automobile alternators suitable for wind energy?
- What adjustments are required to convert an automobile alternator into a functional wind generator?
- What is it about Delco-style alternators that makes them so popular?
- Which WindyNation blades work best with Delco-style PMA wind generators?
Perhaps we asked that last question ourselves! In any case, if you’ve ever wondered about repurposing automobile alternators, now’s your chance to learn everything you need to know.
Wind power enthusiasts are increasingly common around the world, taking advantage of excess supplies of alternators or motors that were originally intended for purposes other than generating electricity from the wind. Fisher & Paykel washing machine motors are quite popular in Australia and New Zealand, as these machines utilise big permanent magnet motors. Ametek, Inc. is best known in North America for their tape drive motors, which were once readily available and immensely popular for constructing wind generators.
However, when it comes to DIY modest wind power, the Delco brand of permanent magnet alternators is likely the most popular.
Why are Delco-style Alternators So Popular?
The Delco moniker is derived from Dayton Engineering Laboratories Co, a long-time supplier to General Motors. Delco had a long and illustrious history, which included the invention of the first practical battery ignition system. Hundreds of key components for American-made autos were manufactured by the enterprise, which was absorbed into a variety of larger mega-corporations. GM still uses the Delco brand name, especially for its ACDelco components division, but the corporation has come a long way since its early pioneering days.
Since the early 1980s, the American auto industry has had a lot of excess production capacity, which has often gone into generating a lot of components that don’t always wind up in automobiles. Even though these alternators didn’t find a place under a hood, they found a way to be useful. Delco has experienced a rebirth among wind power aficionados. For usage in small wind generators, repurposed vehicle alternators have become exceedingly popular and relatively cost-effective.
Most ACDelco generators that are sold specifically for use as a wind generator have been repurposed or rebuilt. The reason for this is that when a Delco automobile alternator is employed in a wind turbine, it operates under different conditions than a permanent magnet alternator.
What Modifications are Necessary?
The stator of an automobile alternator is wound to function at extremely high RPMs, owing to the alternator’s luxury of being turned by a powerful, high-rpm engine. The operating rpm of a Delco vehicle alternator is around three times that of the crankshaft of the car engine. The crankshaft of a car rotates between 1000 and 4000 revolutions per minute. As a result, a Delco automobile alternator is built to provide adequate charging voltage and amperage at 3000-12000 rpm.
In 25 mph wind, a modest wind turbine with a rotor diameter of about 60 inches may reach 850 revolutions per minute! The threshold for a normal Delco automobile alternator to even begin charging a 12 volt battery bank is 850 rpm!
When using a Delco automobile alternator as a wind generator, it is imperative that the alternator be modified to run at low RPMs. This is achieved by two complex modifications:
- The stator windings on a Delco vehicle alternator are replaced with a stator with more turns of lower gauge wire.
- On the rotor, high-powered Neodymium magnets are used, which produce more power than conventional magnets.
Where Can I Buy Quality Delco Alternators for Wind Turbines?
WindBlue manufactures high-quality Delco Permanent Magnet Alternators (PMAs), and they are ethical and transparent in their assessment and presentation of the PMAs’ expected power output. They generally achieve this by displaying a Power Curve that shows the output of their alternators under load. This is in contrast to some other re-sellers of modified Delco PMAs that only show open-circuit voltage readings, which are essentially useless indicators of a PMA’s output.
Have Reasonable Expectations
When it comes to Delco alternators, it’s critical to have realistic expectations for the amount of power these devices will provide. In other words, you shouldn’t anticipate a Delco PMA to produce a power production miracle because the amount of power a wind generator or alternator can produce scales with:
- The maximum amount of copper that can be crammed into a stator.
- The number and size of powerful neodymium magnets that can be used on the rotor.
Because a Delco automobile alternator is about the size of a cantaloupe fruit, the amount of copper and magnets it can hold is limited.
A automobile alternator, maybe more importantly, was designed to be installed under the hood of a vehicle. This is not meant to be a criticism of their quality or even their suitability as wind generators. It is a basic reality that the specs for a car alternator and a wind generator are vastly different. A car alternator, for example, will not be weather-proof because it is normally protected from rain and mist because it is located under the hood. Second, the stator must be rewound in order to provide a voltage adequate for battery charging, as we’ve just mentioned. Third, because it is turned by the automobile’s engine, which may produce at least 100 horsepower (76000 Watts! ), a car alternator does not need to be particularly efficient at generating energy.
Great Way to Learn How to Build a Wind Generator
Nonetheless, we are heartened by the thousands of people who have learned the foundations of wind power via Delco PMAs and are now using them to generate significant amounts of electricity.
We’ve put WindyNation blades through their paces on a variety of WindBlue alternators, and we prepared this section to serve as a resource for consumers considering WindyNation aluminum wind turbine blades in conjunction with a WindBlue alternator.
On the WindBlue 540 and 520 series PMAs, we tested numerous sets of our blades. The load for all of the experiments was a 12 volt battery bank.
Three of our 28-inch HyperSpin blades performed admirably with the WindBlue 540. In 11-13 mph winds, we measured 2-4 Amps of power into a 12 volt battery bank. We measured roughly 10 amps of output into a 12 volt battery bank in very high gusts (20-25 mph). The 540 is ideally suited for the HyperSpins. The 540 PMA is wound for high voltages at low RPMs, allowing it to charge in low to medium winds. As a result, the unit’s Amperage output suffers slightly.
The WindBlue 520 worked best with the 5-blade HyperSpin set, which offers a good balance of torque and speed. This alternator produces more amps than the 540, but it takes a steady 9 mph wind to start charging a 12-Volt battery. The alternator was able to produce 3-5 amps in a 12 mph wind. The 540 produced 12-17 amps in 20-25 mph wind, which is a reasonable amount of power for a little PMA.
Overall, we were impressed with WindBlue’s alternator’s performance. If you’re dead set on employing a Delco for your wind turbine project, we recommend the WindBlue. If you’re looking for something a little more powerful, we recommend the Windtura 500 PMA.
Anyone can see the appeal of modified Delco automobile alternators for do-it-yourself wind power: LOW COST.
Thousands of DIYers utilize these devices to build modest, low-cost wind turbines all around the world. It’s critical to have realistic expectations regarding how much power a Delco-style alternator will produce when acquiring one. Furthermore, because the Delco alternator must be “rebuilt” for use in a wind turbine, it is critical that you obtain a Delco alternator from a reliable and honest company. A Delco car alternator that has been adjusted by an inexperienced person or a company that takes shortcuts will have poor performance, cogging, and will most likely fail on you.
A treadmill uses how many amps?
For the power needs, all Green Series treadmills require a 20 amp “dedicated circuit” with a non-looped (isolated) neutral/ground. (ONE TREADMILL PER DEDICATED 20 AMP OUTLET) Simply put, this implies that nothing else should be running on the same circuit as the outlet you’re plugging into.
What is the wattage of a treadmill?
The amount of electricity consumed by your treadmill is determined by its wattage.
It’s critical to understand your treadmill’s wattage and power usage in order to determine prospective electric bills.
The wattage rating of your treadmill will be influenced by the size of the motor it has.
The majority of treadmills require between 300 and 900 watts of power, and simple calculations may be done to estimate how much electricity your machine will use and how this would affect your bills.
To figure this out, take a look at how often you use your treadmill over the course of a month and multiply it by the maximum treadmill wattage.
For example, if you have a 600 watt treadmill and utilize it for about 18 hours each month, your treadmill will consume 10.8 kilowatts per month.
Using this formula, you’ll be able to locate this cost on your electricity statement with ease.
