    摘要： An outer-rotor brushless direct-current (BLDC) motor is provided including a rotor shaft, a motor housing having an open end and a closed end that supports a first motor bearing, a stator core having an aperture extending therethrough, a stator mount coupled to the open end and including an elongated cylindrical member projecting into the aperture of the stator core and a radial wall that supports a second motor bearing, an outer rotor, and a rotor mount including an outer rim arranged to couple to the outer rotor and an inner body mounted on the rotor shaft. An intermediate bearing is received at least partially within the aperture of the stator core to radially support the stator core relative to the rotor shaft.

    摘要： A power tool is provided including a housing, a brushless direct-current (BLDC) motor, and a gear assembly. The motor includes a stator having an inner stator, a rotor shaft extending along a center axis and including a first bearing and a second bearing; an outer rotor, a first end cap, and a second end cap. The first end cap includes a radial back plate having a center opening in the radial back plate through which the rotor shaft extends and pins projecting around the rotor shaft and parallel to the rotor shaft. The gear assembly is mounted on the first end cap and includes planetary gears supported by the pins in engagement with the rotor shaft.

    摘要： A motor is provided including: a stator including a stator core, stator windings, and an end insulator; a rotor rotatably received within the stator; and stator terminals supported by the routing insulator and extending away from the stator. Each stator terminal includes a main body having a curved portion, a tang portion folded over the main body and receiving a portion of a magnet wire therein to make an electrical connection with at least one of the stator windings, and a terminal pin projecting axially away from the stator core. The stator core has a maximum diameter of less than or equal to approximately 34 mm defining an outer envelope of the stator, and the stator terminals are fully contained within the outer envelope.
