Abstract: A vehicle door checker integrated with a power drive unit for an automobile door includes a direct current permanent magnet electric motor subject to cogging torque. The electric motor includes a central shaft. The vehicle door checker also includes a cogging torque increase device that is mounted to the central shaft externally of the motor. The cogging torque increase device includes pairs of oppositely magnetized permanent magnets that are mounted coaxially in a stator and rotor respectively about the motor shaft. The stator magnets and the rotor magnets shift into and out of alignment with each other as the shaft is rotated such that the motor is held in multiple discrete stable positions that correspond to check positions of an automobile door.

Abstract: A power drive module for a vehicle power door includes a housing, a drive mechanism arranged in the housing and configured to move a drive element, and a brake assembly arranged in the housing. The brake assembly includes a brake ring operatively coupled to the drive mechanism. A brake band is wrapped about the brake ring and movable between a normally engaged position relative to the brake ring and a disengaged position relative to the brake ring. A brake release actuator is operatively connected to the brake band and configured to move the brake band between the engaged and disengaged positions with the brake ring in response to an electrical signal.
