摘要： An electric motor includes a stator assembly including a lamination stack, a printed circuit board assembly (PCBA), and a plurality of windings. The PCBA is coupled to the lamination stack at a first axial end of the stator assembly. The windings are wrapped about the lamination stack to form coils. Each winding includes crossover portions extending about a portion of a circumference of the stator assembly to connect pairs of opposite coils. The crossover portions are located at a second axial end of the stator assembly opposite the first axial end.

摘要： 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.
