Abstract: The present disclosure relates to security mechanisms for electric motors and associated systems. For example, the present technology includes a powertrain assembly having (1) a motor having multiple sets of coils; (2) a drive circuitry electrically coupled to the multiple sets of coils; and (3) a security unit electrically coupled to the drive circuitry and the multiple sets of coils. The security unit is configured to short-circuit at least one set of the multiple sets of coils responsive to a signal from a controller. The signal indicates that the motor is, or has been, turned off.

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 robotic system is proposed whereby the system comprises drivers which integrate the power switches and communications electronics for communicating over power lines or wirelessly or over another shared communications channel. In a robotic system comprising such drivers, one or more central controllers communicate with at least one actuator driver across a communications channel, wherein the communications channel is subject to interference caused by an actuator, and wherein at least one of the communication and the operation of the actuators is modified in anticipation of interference occurring such that reliable communication can be assured.
