Abstract

A power tool is provided including a tool housing, a transmission, and a brushless motor disposed in the tool housing that includes an inner stator, an outer rotor, and a rotor shaft. A stator mount assembly is provided including a stator mount including an axial member secured to the stator, and an integrated mounting member including a radial member secured to the stator mount, a ring gear mount extending from the radial member away from the motor, and a ring gear supported by the ring gear mount. The transmission is secured to the tool housing, and it includes a transmission housing having a generally cylindrical body, and a planetary gear set including a carrier and at least one planet gear rotatably mounted to the carrier. The ring gear meshes with the at least one planet gear. In an embodiment, the transmission housing is integrated with the stator mount assembly.
