Abstract
A power tool is provided including a tool housing including a motor housing and a handle portion; a battery receptacle disposed at an end of the handle portion opposite the motor housing, the battery receptacle being configured to receive a battery pack; and a brushless DC motor including a stator and a rotor. The stator includes a stator lamination stack, an end insulator, and input terminals supported by the end insulator. A power circuit board is coupled to the input terminals to supply power to the motor. The motor produces a maximum power output of at least 1600 watts for driving an output shaft at a maximum torque of at least 30 inch-pounds and a maximum speed of at least 8000 rotations-per-minute.
