Abstract
A motor system and a method of operating an electric motor that includes monitoring a voltage of power supplied to the motor by a mircrocontroller located in the motor; storing energy within the motor; detecting if the voltage drops below a nonzero threshold; and if the voltage drops below the threshold, immediately operating the microcontroller with the stored energy to store a state of the motor in non-volatile memory located within the motor, and ceasing operation of the motor. This motor operation may be employed with multiple motors in vehicles where voltage drop may occur during an engine start of a vehicle stop/start event.
