PWM is used in most DC motor variable speed applications. It seems to be about the only practical way to get low end torque and high efficiency. I am kind of suprised that some of that stuff has not gone to AC motors and a varaible frequency drive arrangment in EVs or am I just unaware of new developments? -- Composed on a 100% Microsoft and Windows free computer with Mandrake Linux 9.1
