Abstract
A motor assembly and method of operating the motor assembly include a motor, a memory to store calibrated parameters of the motor, and electronics coupled to the memory and the motor. The electronics are configured to retrieve the calibrated parameters from the memory, provide the calibrated parameters to an external system, and receive control signals for driving the motor from the external system. The control signals are based on the calibrated parameters. The calibrated parameters include a motor speed versus no-load current relationship for the motor determined by a procedure that includes performing an initial calibration of the motor, wearing in the motor after performing the initial calibration, performing a final calibration of the motor after wearing in the motor, and storing the calibrated parameters in the memory based on the initial calibration and the final calibration.
