Easy Wind Power For Homes Tips – Choosing The DC Motor


If you are searching for easy wind power for homes system that works, one of the best solution is to build it yourself. Building a residential wind turbine is not that difficult. In actual fact, you can get it done with a budget as small as $150.

There are many components that make up the home wind generator system. One of the key parts is the DC motor. In this blog post, I am going to share some information on choosing the right DC motor.

Where To Find Cheap DC Motor

Some people may be wandering where they can get their hands on some cheap DC motor. The first place that I will normally do my research is at Ebay.

There are literally thousands of motor listed in Ebay. What type of motor you should keep an eye on?

Here are a few criteria. Look for a DC motor with:

1) High Direct Current (DC) voltage.

2) High current output.

3) Low Revolution Per Minute (RPM) rating.

Here’s a tip. Look for permanent magnet alternators. Usually, these motors are more expensive, but they are designed for wind turbine use.

Choosing The DC Motor

Here’s a rule of thumb on DC motor you can use when searching on Ebay.

1) Look for a motor that can generate at least 12V at low RPM.

2) If a motor is rated 325 RPM at 30 Volts, when used as a generator, you can expect it to produce 12 volts or more at some reasonably low rev.

If possible, find a DC motor with RPM rating of under 400.

3) The shaft size of the motor should be over 5/8”. The DC motor on a home wind generator goes through a lot of wear and tear throughout its life time.

Therefore, the motor needs adequate bearings or bushings to accommodate the constant spinning and harsh outdoor treatment it will receive.

It took me a couple of minutes of searching in Ebay and I managed to locate 2 offers that meet the criteria.

    The community must decide abut he use of more hydropower as compared to wind power, because the former can meet more power demands as compared to wind, this does not mean that wind power should not be used, it can meet the short fall.

    Though wind power can meet the shortfalls but cannot be the only source of energy, we need to use other sources like solar panels and wind turbines. Though the wind energy industry is gaining popularity and is forging ahead in many countries and has given people a neat and clean energy which does not pollute the atmosphere.
