Abstract
A brushless motor includes a stator assembly including a generally-cylindrical stator body having a center bore, teeth extending from the stator body towards the center bore and defining slots in between, and windings wound around the teeth; and a rotor assembly rotatably received within the center bore and includes a rotor shaft and a generally-cylindrical rotor body. The motor further includes at least one rotor bearing mounted on the rotor shaft, and at least one bearing support member supporting the rotor bearing. The bearing support member includes a radial body forming a bearing pocket for receiving the rotor bearing therein, and axial post inserts received within the slots of the stator assembly between adjacent sets of windings and in contact with an inner curved surface of the stator body to support the rotor bearing with respect to the stator assembly along a center axis of the center bore.
