Abstract: Power tools described herein include a housing, a brushless direct current (DC) motor, a non-conductive terminal mount, and a plurality of terminals. The housing has a motor housing portion, a handle portion, and a battery pack interface. The brushless DC motor is located within the motor housing portion and has a rotor and a stator. The non-conductive terminal mount is located on an outer peripheral surface of the stator and includes an angled surface. The angled surface is not substantially parallel to a longitudinal axis of the motor. The plurality of terminals is mounted on the angled surface of the terminal mount. Each of the terminals is angled in a first direction such that the terminals are not substantially parallel to the longitudinal axis of the motor.

Abstract: A motor assembly for use with a power tool includes a motor housing, a brushless electric motor disposed at least partially in the motor housing, and a PCB assembly coupled to the motor housing. The PCB assembly includes a heat sink, a power PCB coupled to a first side of the heat sink, and a position sensor PCB coupled to a second side of the heat sink opposite the first side and in facing relationship with the motor.

Abstract: A brushless electric motor includes a stator and a rotor. The stator includes a core defining a plurality of stator teeth, a first end cap proximate a first end of the core, a second end cap proximate a second end of the core, and a plurality of coils disposed on the respective stator teeth. The stator also includes a plurality of coil contact plates overmolded within one of the first end cap or the second end cap that short-circuit diagonally opposite coils on the stator.
