Abstract:
A power tool with a combined printed circuit board (PCB) that reduces internal wiring of the power tool and provides a large amount of air flow to internal components. In some instances, the combined PCB has a surfboard shape and includes a motor control unit and power switching elements (Field Effect Transistors or FETs). The combined surfboard PCB is located above the trigger, but below the motor and drive mechanism. In other instances, the combined PCB has a doughnut shape and is located coaxially with a motor shaft. The combined PCB may be positioned between a doughnut-shaped control PCB and the motor.

Claim (Index 14):
A power tool comprising:\n a frame; a brushless direct current (DC) motor supported by the frame and having a motor shaft arranged to produce a rotational output; a combined printed circuit board (PCB) having a Hall sensor, power switching elements, and a first through-hole, wherein the motor shaft extends through the first through-hole; a heat sink attached to an end of the brushless DC motor, wherein the heat sink has a second through-hole through which the motor shaft extends and wherein the heat sink is located between the brushless DC motor and the combined PCB; and a control PCB configured to receive motor positional information from the Hall sensor and control the power switching elements to drive the brushless DC motor, wherein the control PCB includes a processor and a memory; wherein the second through-hole is larger than the first through-hole and the Hall sensor is located radially outward of the first through-hole and radially inward of the second through-hole; wherein at least two power switching elements on the combined PCB are located on a first side of an axis that bisects the first through-hole of the combined PCB and is perpendicular to the motor shaft; wherein at least two power switching elements on the combined PCB are located on a second side of the axis that bisects the first through-hole of the combined PCB and is perpendicular to the motor shaft.
