1. A surgical instrument, comprising:

  • an end effector, comprising;

    an elongated channel configured to support a staple cartridge; and

    an anvil pivotably connected to the elongated channel, wherein at least one of the anvil and the elongated channel is movable relative to the other to transition the end effector between an open configuration and a closed configuration;

    a closure tube configured to transmit a closing motion to the end effector for transitioning the end effector from the open configuration to the closed configuration;

    an electric motor operably coupled to the closure tube, wherein the electric motor is configured to motivate the closure tube to cause the end effector to transition from the open configuration to the closed configuration during a closure cycle; and

    a control circuit electrically connected to the electric motor, wherein the control circuit is configured to cause the electric motor to change the closing motion of the surgical instrument by automatically stopping and restarting the closing motion during the closure cycle.
