  • AC Variable Speed Drives - apprep.com

    A slip ring (wound rotor motor) has a high starting torque, compared to its counterpart, the standard induction motor, and an additional benefit is the ability to vary the speed. While that speed variation is only accurate between 50 and 100 percent of full load speed, that's something that isn't possible with a standard induction motor.
