Power tool

A power tool comprising:

• a gear case having a spindle;
• a motor case connected to a rear end of the gear case defining a longitudinal axis;
• a handle portion attached to a rear end of the motor case and elongated along the longitudinal axis;
• a battery receptacle disposed at a rear end of the handle portion intercepting the longitudinal axis;
• a motor housed inside the motor case, the motor having a stator, a rotor rotationally arranged inside the stator, and a fan in rotational connection with the rotor, the motor produces a maximum power output of at least 1600 watts for driving the spindle;
• and
• a power module including a circuit board disposed along a plane that is substantially perpendicular to the longitudinal axis and a plurality of power switches for driving the motor mounted on the circuit board, the power module housed in the motor case adjacent the motor,
• wherein a circumference the motor case around the motor is approximately 1.5 to 2 times greater than a circumference of a gripping area of the handle portion near the end of the handle portion.
