Abstract: A windshield wiper system includes a three-phase motor (14), the three-phase inverter (34), a brake circuit (36), and a controller (18). The controller transmits commutation signals to the three-phase inverter to drive the motor according to an inboard-to-outboard speed profile and to drive the motor according to an outboard-to-inboard speed profile. The controller activates the brake circuit based on the inboard-to outboard speed profile, or the outboard-to-inboard speed profile, and a direct current bus voltage.
