Zusammenfassung:An apparatus includes a body, a motor, a shaft, a stapling assembly, and an electrical potential shifting device. The body includes a firing switch configured to generate a motor drive signal including at least one of a motor activation signal portion or a motor deactivation signal portion. The motor includes a first power terminal and a second power terminal which define an electrical potential energy differential therebetween. The motor is configured to selectively activate and deactivate in response to the electrical potential energy differential. The first power terminal is coupled to a power supply and the second power terminal is coupled to the electrical potential shifting device. The electrical potential shifting device increases the electrical potential energy differential of the motor in response to detecting the motor activation signal portion and decreases the electrical potential energy of the motor in response to detecting the motor deactivation signal portion.
