PWM vs. Linear Amplifier effect on motor efficiency and heat losses in motor coils
PWM vs. Linear Amplifier effect on motor efficiency and heat losses in motor coils
(OP)
Hi
I have a question related to PWM vs. Linear Amplifier. I know the PWM amplifiers run cooler than standard linear power amplifiers and hence the PWM amplifiers has higher efficiency. I am wondering what about the motor itself. Are both PWM vs. Linear Amplifier produces the same heat losses on the motor?

Linear amplifiers are real specialty items now, really only used in super-precision applications that cannot tolerate the vibration or EMI from a switching amp.
