Abstract: An electric motor includes a rotor assembly including a rotor shaft and a stator assembly including a plurality of stator segments. Each stator segment includes a core, an insulator at least partially covering the core and including a mounting portion, and a coil winding including a wire lead. The plurality of stator segments include a first stator segment and a second stator segment adjacent the first stator segment in a circumferential direction. The electric motor also includes a printed circuit board assembly coupled to the mounting portions and configured to direct electric current to each coil winding. The printed circuit board assembly includes a plurality of peripheral slots formed at intervals about a periphery thereof. The wire leads are received into the peripheral slots and soldered to electrically connect the wire leads to the printed circuit board assembly.

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.
