Abstract
A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position toward a driven or bottom-dead-center (BDC) position for driving a fastener into a workpiece, a gas spring mechanism for driving the driver blade toward the BDC position, and a lifter assembly having a rotary lifter for returning the driver blade from the BDC position toward the TDC position. The powered fastener driver further includes an arm upon which the rotary lifter is supported, a motor which, in a first position of the rotary lifter, provides torque to the rotary lifter to return the driver blade from the BDC position toward the TDC position, and a brake mechanism including an electromagnet which, when activated, causes the rotary lifter to move from the first position toward a second position in which the rotary lifter is not engageable with the driver blade.
