DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

The quest for energy efficient electric motors has generated a lot of interesting ideas. One of the latest is said to push the efficiency of induction motors to better than super-premium levels by ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.
