Re: [TCML] speeding up sync motors ?

Hey Chris,

As soon as you go past 120hz, the eddy currents generated in the iron laminations of the motor heat the thing up -  quite a lot. More than this frequency and you will have to redesign the laminations to cope. Tesla did this with his high frequency generators.
