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 9):
A power tool comprising:\n a brushless direct current (DC) motor having a rotor and a stator, wherein the rotor is coupled to a motor shaft to produce a rotational output, wherein the motor shaft is configured to rotate about a longitudinal axis, which extends through the motor shaft; a transmission coupled to the motor shaft configured to be driven by the rotational output; a combined printed circuit board (PCB) having a Hall sensor, power switching elements, and a first through-hole, wherein the power switching elements are mounted on the combined PCB in a flat orientation and wherein the longitudinal axis 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 longitudinal axis extends and wherein the heat sink is located between the brushless DC motor and the combined PCB; 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; and a cable that communicatively couples the combined PCB with the control PCB.
