Is a PM Generators output greater than an A/C motors input?

  1. Sep 17, 2011 #1
    Hi, If I powered a permanent magnet generator like one found in a wind turbine, with lets say with a 1/2 hp A/C motor for example and directly coupled them together or used a gear reducer to increase the torque and rpm's, would the output watts created by the generator be greater than the wattage needed to run the input motor?
    I'm asking this because what I've heard is that a pm generators required drive torque under load is much less than a conventional generator. I'm no electrical engineer by any means but I am and industrial mechanic specializing in rotating assemblies and and other boiler plant equipment and operations. Any help would be greatly appreciated.

    Thank you, Mark

    No never you'd be violating the law of conservation of energy.
