AC Motor Drive Application Guide by Vishay
According to Vishay, a motor can be a simple induction machine that rotates with the connection of a simple AC voltage. In applications that require more precise control of speed, torque, or positioning, it is more common to use a 3-phase motor. In order to control this type of motor, signals must be generated that cause the motor to spin properly, using feedback to close the loop and regulate the desired parameters.
