Hello this is my first post, please let me know if I'm breaking any rules, I'm still a bit hazy on them. I am in the process of making a permanent magnet induction generator from and old washing machine induction motor. The motor is rated 1725 rmp, 115 volts 6.3 amps at 1/3 horsepower. It is a single phase motor. I intend to use it for a wind turbine so running the rotor 5% above rated rpm's is not an option. Instead I would like to drill out the rotor and put in cylindrical Neodymium magnets 3/8" diameter by 1" length. If i want to run the engine at low RPM (say 0 to 600 for a turbine) how many magnets would I need to use to achieve an output of 500 watts or more, if that is possible. Thanks all.
