Why do DC motors spin so fast?

22 Mar, 2019

AC synchronous motors can only run at synchronous speed, which depends on the number of poles, but can never be more than 3600 rpm at 60Hz or 3000 rpm at 50 Hz. AC induction motors alway run slightly below the speed of a synchronous motor with the sa...
