Abstract
A brushless DC motor for use with a power tool includes a stator surrounding a rotor, an output shaft with first and second ends that is fixed to the rotor to transmit movement of the rotor to the output shaft, first and second bearings positioned on the output shaft adjacent the first and second ends, a fan coupled to the output shaft between the first and second bearings to rotate with the output shaft relative to the stator, and a brass bushing with an outer diameter coupled to the output shaft and positioned between the first and second bearings closer to the first bearing than to the second bearing. A hub portion of the fan is coupled to the output shaft and fins extend radially outward away from the hub portion. An outer diameter of the brass bushing is less than the outer diameter of the hub portion.
