    I was given a brand new blower motor and was looking for opinions on how suitable it would be.

    RPM 1550 (2 Speed)

    Let me know what you think.

    Hi Casey,

    "looking for opinions on how suitable it would be."
    I'll assume you are asking how suitable this motor would be for generating power, used as a wind turbine.
    I believe what you have is an induction type motor.
    Re: Induction Motor Conversion (process of converting an AC induction motor to an alternator.)
    In other words both the armature and the field are coil wound, no magnets in it.
    It would need to be converted to an alternator by remaking the armature by removing it's coils, turning down the armature, adding powerful (neo) magnets etc.
    In addition to this, the field wiring would need to be rewired to delta or star wiring.

    It's all doable but a MAJOR process that involves a lot of study, time and machine work to accomplish not to mention cost. (I've gone this route and it's a wonderful learning experience but I would not recommend it unless you want to devote all of the above).

    Bottom Line:
    I don't think that the motor that you have would be a suitable choice for an induction motor conversion.
    If you go to and look for posts by "Zubbly" you will learn a great deal about induction motor conversions. Zubbly has since passed away but his work with induction motor conversions is well documented there.

    I would recommend that you go with an alternator (preferably 3 phase) that has a rotor with neo magnets or perhaps a Permenant Magnet DC motor. These are good for learning but many will not produce much current.

    After years of trial and error and reading about wind turbines, I've come to the conclusion that your best investment would be to get an alternator that is specifically built to be used as a wind turbine such as the WindTura 500 or 750.
    The WindTura 500 is what I have now.
