Electric motor for a power tool

A brushless DC motor for use with a power tool, the brushless DC motor comprising:

• a rotor having a body;
• a stator surrounding the rotor;
• an output shaft fixed to the rotor such that movement of the rotor is transmitted to the output shaft, the output shaft having a first end and a second end;
• a fan including a hub portion having an outer diameter, the hub portion coupled to the output shaft to rotate with the output shaft relative to the stator, the fan including a plurality of fins extending radially outward away from the hub portion and in an axial direction of the output shaft toward the rotor;
• a bearing coupled to the output shaft;
• and
• a brass bushing having an outer diameter, the brass bushing coupled to the output shaft between the rotor and the bearing,
• wherein the outer diameter of the brass bushing is less than the outer diameter of the hub portion of the fan.

A power tool comprising:

• a housing;
• a battery connection portion supported by the housing, the battery connection portion configured to receive a battery pack;
• a drive mechanism configured to operate a working element;
• and
• a brushless DC motor positioned within the housing and connected to the drive mechanism, the brushless DC motor electrically coupled to the battery connection portion and including
• a rotor,
• a stator surrounding the rotor,
• an output shaft fixed to the rotor such that movement of the rotor is transmitted to the output shaft, the output shaft having a first end and a second end,
• a first bearing coupled to the output shaft adjacent the first end of the output shaft,
• a second bearing coupled to the output shaft adjacent the second end of the output shaft,
• a fan having a hub portion coupled to the output shaft to rotate with the output shaft relative to the stator, the fan positioned on the output shaft between the first bearing and the second bearing, the fan including a plurality of fins extending radially outward away from the hub portion and in an axial direction of the output shaft toward the rotor, the hub portion having an outer diameter, and
• a brass bushing having an outer diameter, the brass bushing coupled to the output shaft between the first bearing and the second bearing,
• wherein the outer diameter of the brass bushing is less than the outer diameter of the hub portion of the fan.
