Abstract

A motor assembly is presented. A motor assembly can include at least one motor; a memory to store calibrated parameters related to the at least one motor; and electronics coupled to the memory, the at least one motor, the electronics including interfaces to couple with a clamping device and a system to control the operation of the at least one motor. The calibrated parameters are determined for the at least one motor with a procedure that includes performing an initial calibration of the at least one motor; wearing in the at least one motor; performing a final calibration of the at least one motor; and storing calibration data in the memory. In some embodiments, the at least one motor can include a clamping motor and/or a firing motor. In some embodiments, lifetime parameters are stored in the memory.

Claims19

Dependent claims

A method of calibrating a motor in a motor assembly, comprising:

acquiring an assembled motor assembly, the motor assembly including the motor, a memory to store predetermined calibrated parameters of the motor, and electronics coupled to the memory and the motor, the electronics including interfaces to couple with a clamping device and a system, external to the motor assembly, to control operation of the motor, the electronics being configured to:
retrieve the predetermined calibrated parameters from the memory;
provide the predetermined calibrated parameters to the external system;
and
receive control signals for driving the motor from the external system, the control signals being based on the predetermined calibrated parameters;
performing a final calibration of the motor;
and
storing calibration data in the memory of the motor assembly;
wherein the predetermined calibrated parameters comprise a motor speed versus no load current relationship for the motor determined by a procedure including:
acquiring no-load data for the motor;
and
fitting a function to the no-load data to determine the motor speed versus no load current relationship.
