Abstract

A power tool is provided including a tool housing, a brushless direct-current (BLDC) motor disposed in the tool housing, and a transmission. The motor includes a stator including a stator core having an aperture extending therethrough and stator windings, a rotor including a cylindrical rotor core supporting at least one permanent magnet around an outer surface of the stator core, a rotor shaft rotatably coupled to the rotor, and a stator mount including a radial member near a front end of the stator and an axial member secured to the stator. The transmission is secured to the tool housing and includes an input member coupled to the rotor shaft, and an output member configured to be driven by rotation of the input member. The radial member of the stator mount is secured to the transmission to support the stator at least radially within the rotor.
