Abstract

A surgical stapler is presented having a firing assembly, a motor, and a motor control circuit. The firing assembly is configured to translate along a longitudinal axis such that translation of the firing assembly in a distal direction is configured to deploy staples from an end effector during a firing stroke. The motor assembly includes a motor configured to drive the firing assembly along the longitudinal axis. The motor control circuit is configured to receive a firing signal indicating initiation of the firing stroke, drive the motor with a motor drive signal comprising a pulse width modulated (PWM) signal having a first constant duty cycle such that the firing assembly is translated through an initial distance, and increase a duty cycle of the PWM signal based at least in part on movement of the firing assembly through the initial distance.
