Abstract
A brushless electric motor having an internal stator assembly including a lamination core and a heat sink. The motor includes an external rotor assembly adapted for rotational movement relative to the stator assembly about a central shaft. The motor also includes a tubular bearing support received within an inner space of the stator assembly adjacent to the lamination core and adjacent to the heat sink to facilitate a reduced axial length of the motor, the shaft being pressed into a bearing assembly retained within the bearing support to allow rotation of the shaft and therefore of the rotor assembly with respect to the stator assembly. The rotor assembly may have a cover with a central hub and a central shaft mounted within the hub. The motor may have a bearing assembly retained within the bearing support and receiving the shaft to allow rotational movement of the rotor assembly about the stator assembly.
