'Electric drives' is a term used to describe DC and AC electric motors that provide continuous rotarmotion. They are often controlled by 'electronic drivesystems' designed to control the commutation, speedand torque output of the motor.
'Electrical Actuators' provide linear or angular displacement (as opposed to continuous rotation)
