    Abstract: A power tool including a motor configured to rotatably drive an output shaft, a variable motor speed control input, a motor speed limit input, and a motor controller. The motor controller includes an electronic processor and a memory configured to store instructions. When executed by the motor controller, the instructions configure the motor controller to detect a motor speed limit from a setting of the motor speed limit input, and detect a variable speed control setting from the variable motor speed control input. The motor controller generates a motor speed control signal for driving the motor based on the detected motor speed limit and the detected variable motor speed control setting, and transmits the motor speed control signal to a motor driver circuit configured to drive the motor at a speed based on the motor speed control signal.

    Abstract: The present disclosure is directed to a power tool including a motor housing and an electric motor situated within the motor housing. The electric motor is configured to provide rotational energy to rotate an output device of the power tool about an output axis. The power tool also includes a cover configured to cover at least a portion of a surface of the motor housing that faces the output device. The power tool further includes a first lighting device located within the cover and a second lighting device located within the cover. The first lighting device and the second lighting device are located around the output axis and are separated from each other by at least 130 degrees about the output axis. The power tool also includes first power wires configured to provide power to the first lighting device from a power source of the power tool.
