Abstract: A method of performing an authentication process to authenticate an electric motor unit includes establishing, by an external controller, secure encrypted communication with motor electronics of the electric motor unit, and sending, by the external controller, an authentication request to the motor electronics over the secure encrypted communication. The method further includes receiving, by the external controller, an authentication response from the motor electronics, verifying, by the external controller, a motor of the electronic motor unit as an authorized part based on the authentication response, and enabling control of the motor by the external controller only after successful authentication.

Abstract: Described herein is an electric motor drive system, including at least one power phase line, an external controller configured to generate a drive signal and provide the drive signal to the at least one power phase line, and motor electronics. The motor electronics include at least one switch coupled between the at least one power phase line and at least one electric motor terminal, and an internal controller configured to cooperate with the external controller to perform an authentication process therebetween. The external controller is further configured to cause the at least one switch to electrically couple the at least one power phase line to the at least one electric motor terminal in response to success of the authentication process.
