ABSTRACT:
A discontinuous drive power tool assembly for generating rotational torque includes a spindle having a first end portion and a second end portion. The first end portion of the spindle is configured to engage and rotate an object. The tool assembly also includes a pulse hammer selectively engagable with the second end portion of the spindle, and a motor that includes a motor shaft engagable with the pulse hammer. The motor is configured to rotate the pulse hammer. The tool assembly also includes a rotational position sensor disposed adjacent the motor. The rotational position sensor is configured to measure the rotational position of a second portion of the motor shaft which is opposite the first end portion of the motor shaft during operation of the tool assembly.
