A multi-function motor. The multi-function motor can operate in different operating states to perform different functions. For example, the motor can advance a firing element during a first operating state, retract the firing element during a second operating state, and generate amplified haptic feedback during a third operating state. The electric motor can rotate in a first direction to advance the firing element, can rotate in a second direction to retract the firing element, and can oscillate between the first direction and the second direction to generate the amplified haptic feedback. A resonator can be secured to the motor. The center of mass of the resonator can be balanced with respect to the axis of rotation of the resonator. Further, the resonator can comprise a natural frequency, and can oscillate within a range of amplifying frequencies inclusive of the natural frequency during the third operating state.
