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 along a longitudinal axis; a handle portion extending from a rear end of the motor case along the longitudinal axis; a motor housed inside the motor case; a fan in rotational connection with the motor; at least one air intake arranged at least one of the motor case or the handle portion near the rear end of the motor case; and a power module including power switches for driving the motor and a heat sink. The power module 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.
