Switching the DC current between one terminal and at least one other terminal instead of the AC current causes the rotating magnetic field to stand still and switch to the fixed magnetic field. Since the magnetic field is fixed in the rotor, braking torque is generated and the rotor stops. The strength of the braking force can be adjusted by adjusting the current (applied voltage) flowing through the primary winding and the time during which the current flows.
