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.

The drive assembly has an electrically powered motor and a controller electrically connected to the power supply and to the motor. The controller selectively operates the motor. A transmission mechanically connects the motor to the moving part and selectively displaces the moving part anywhere between the start and fully extended positions when the motor is operated. A manual release is mechanically coupled to the transmission to selectively interrupt the transmission and, during interruption, displaces the moving part towards the start position independent of motor operation.
