    How to Turn an AC Induction Motor Into a DC Motor A

    the motor by a factor of 1/2 or 30 Hz. If we wanted to operate the motor at ¼ speed then the frequency would be reduced to 15 Hz. You’ll also want to keep the stator field relatively constant by keeping the stator currents constant. The ACIM motor is inductive and the stator currents will increase as the input frequency is decreased.
