It's an electrical con game, bait and switch, taking place many times each second that makes a motor turn. AC and DC Motors. AC motors before Tesla were rare, laboratory devices—curiosities.

Consequently, AC motors are less efficient than DC motors. In fact, the DC motor is 30% more efficient than AC motors due to the secondary magnetic field being generated from the permanent magnets ...

To achieve rotation, there has to be some interaction between magnetic flux produced by electromagnetism within the motor. DC motors and AC motors accomplish this task in different ways. DC machines ...

Universal motors can be powered with either direct or alternating current, and each approach has its advantages and disadvantages. AC drive circuits tend to be less pricey than their DC counterparts, ...
