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.

Abstract: Systems and methods of operating power tools. The method includes receiving a command to start a recording mode at a first electronic processor of a first power tool, and receiving at the first electronic processor, a measured parameter from a sensor of the first power tool while a first motor of the first power tool is operating. The method also includes generating a recorded motor parameter by recording the measured parameter, on a first memory of the first power tool, when the first power tool operates in the recording mode, and transmitting, with a first transceiver of the first power tool, the recorded motor parameter. The method further includes receiving the recorded motor parameter at an external device, transmitting the recorded motor parameter to a second power tool via the external device, and receiving the recorded motor parameter via a second transceiver of the second power tool.

Abstract: Brushless direct-current (“BLDC”) motor and control for a power tool. A BLDC motor of a power tool is controlled in either a pulse-width modulation (“PWM”) commutation mode or a centerline commutation mode. When the motor is rotating slowly, the motor is operated using PWM commutation. When the motor is rotating at a speed greater than a threshold speed value, the operation of the motor is transitioned to the centerline commutation mode. When operating in the centerline commutation mode, the high-side field-effect transistors (“FETs”) and low-side FETs can each be used for motor speed control. By switching between speed control using the high-side FETs and speed control using the low-side FETs, the heat generated by freewheeling currents can be approximately evenly distributed among the high-side and low-side FETs.

Abstract: A hand held power tool including a trigger, a motor, an output unit driven by the motor, a switch bridge, and a snubber circuit. The switch bridge is operable to selectively provide power to the motor to drive the output unit in response to activation of the trigger. The snubber circuit is electrically connected in parallel across the switch bridge. The snubber circuit is operable to store energy when power is being provided to the motor, and release the energy when power is not being provided to the motor.

Abstract: A cordless, hand-held power tool, such as a hammer drill/driver, a drill/driver, an impact driver, an impact wrench, etc., that includes a brushless direct current (“BLDC”) motor. Each of the hand-held power tool includes a removable and rechargeable battery pack, electronics, and a BLDC motor that have been designed and balanced to produce a high-performance-capable (e.g., high-power, high-current, high-torque) hand-held power tool. The hand-held power tool is capable of delivering high instantaneous (i.e., short duration) current to the BLDC motor for short-duration high power operation and high continuous (i.e., long duration) current to the BLDC motor for long duration high power operation. Additionally, the short and long duration power is capable of being provided in a smaller (in size) and lighter (in weight).
