AC And DC Motors Reviews

Luckily, there is a pretty simple formula that you can follow that will ensure that the wind generator motor that you choose will perfectly fit your needs.

The first thing you'll need to do is head over to eBay and do a search for wind generator motors. That will bring up quite a few results that you can than filter through using this criteria.

The first thing you need to take a look at is whether the motor is a permanent magnet motor. Most DC motors are permanent magnet motors so you're good in that department. If you're looking for an AC motor than you're going to definitely double check that it's a permanent magnet motor.

Now that you know that it has permanent magnets it's time to take a look at the RPM's it's rated for. Many people fall into the trap of buying a 600 watt motor; however, you need 2000 RPM's to achieve that. You're looking for a motor that is rated for about 650 RPM's.

Next up is the voltage and amperage rating (multiplying them together gives you the wattage rating). Here is where things can get a little tricky. I recommend that first you figure out how much power that you want to produce and than look for a a motor that produces 150% more power than that (just take how much power you want to produce and multiply it by 1.5).

If you're looking to generate 100 watts than you'd look for a motor that produces 150 watts of power. The reason for this is simple. Wind speeds vary and you're simply not going to produce 100 watts all the time. Most of the time you'll produce less which is why you want your wind generator to be producing 100 watts in 'average' wind speeds.

Last up is to check whether it's a low cogging motor. Cogging refers to 'sticky spots' when you turn the shaft of the motor. A motor that cogs isn't going to start up very well in low wind speeds. If it doesn't say whether it's a low cogging motor ask the seller. If they don't know what cogging is just ask them to turn it slow and ask them if there are any sticky points during the turn.

As long as you keep these tips in mind when you go searching for your wind generator motor you're guaranteed to pick out a good one. Just remember that vacuum cleaner motors won't work (a little joke because I've seen some people try to sell them for wind turbines).

If the motor that you find is a little bit out of your price range than don't sweat it. Save up and than buy it because it's going to cause you less problems in the long run. Cheap motors break easier and will cause you nothing but headaches, but if you buy quality right from the start you're going to save money in the long run.
