Abstract

A brushless motor includes a stator attached to a motor case and a rotor. A circuit substrate is attached to the motor case. The substrate includes an electric circuit, which supplies electric current to the stator thereby rotating the rotor. A fan generates and moves air in accordance with rotation of the rotor. A duct guides some of the air moved by the fan to the stator. A flange extends from the stator. The air guided by the duct flows along the flange. This structure reduces the size of the brushless motor while increasing its power.
