Abstract
An electric brushless DC (BLDC) motor includes a stator and a rotor. The rotor includes a rotor shaft, a rotor core, a bearing, and a sense magnet ring. And end cap is radially oriented with respect to the rotor shaft and securely disposed adjacent the stator, the end cap having a first surface facing the stator, a second surface facing away from the stator, a bearing pocket centrally disposed to receive the at least one bearing of the rotor therein to support the rotor, and at least two retention features projecting from the first surface at a distance with respect to one another to form a lateral gap therebetween. A positional sensor board is radially received from a peripheral side of the end cap in contact with the first surface of the end cap and within the lateral gap between the retention features of the end cap.
