... With a DC motor, ramping up the voltage (or duty cycle if pulse-width modulation is being used) controls how fast the motor’s shaft reaches any given speed. With stepper motors, however, changing the voltage does not have any effect on the motor speed. While it is true that changing the voltage chan ...

AC motor
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.Less commonly, linear AC motors operate on similar principles as rotating motors but have their stationary and moving parts arranged in a straight line configuration, producing linear motion instead of rotation.
