An electrically powered surgical instrument includes a surgical end effector having a surgical procedure effecting actuation assembly. A handle is coupled with the end effector. An electric motor is disposed within a shell of the handle and has power terminals and a drive train actuating the assembly when the motor is supplied with power. A break-before-make power supply switch at the handle selectively controls supply of power to the motor. A post-termination braking circuit electrically short-circuits the power terminals when the switch does not supply power to the motor. A method for post-termination braking of an electrical motor utilizes the permanent magnetic field of the motor to counteract an inertia-induced over-stroke characteristic of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power to the motor.
