Abstract

A power tool is provided including a gear case having a spindle, a motor case connected to a rear end of the gear case, a handle portion attached to a rear end of the motor case, and a motor housed inside the motor case. The motor includes a stator, a rotor rotationally arranged inside the stator, and a fan in rotational connection with the rotor. At least one air intake is arranged at least one of the motor case or the handle portion near the rear end of the motor case. A power module including power switches and a heat sink is housed in at least one of the motor case or the handle portion near the rear end of the motor case such that rotation of the fan causes air flow to enter through the air intake and flow near the heat sink and through the motor.
