Patent number: 12255501Abstract: A power tool includes a housing having a motor housing portion and a handle portion. A motor having a motor axis is positioned within the motor housing portion. The power tool further includes a first printed circuit board positioned within the motor housing portion. The first printed circuit board intersects the motor axis. The power tool also includes a second printed circuit board positioned within the motor housing. The second printed circuit board intersects the motor axis. The second printed circuit board includes a conductive high impedance trace that is configured to interrupt electric power to the motor in response to a current that exceeds a current limit.Type: GrantFiled: May 2, 2023Date of Patent: March 18, 2025Assignee: Milwaukee Electric Tool CorporationInventors: Lokeshwaran Rajendran, Ryan A. Khatib, Noah P. Seiler, Mitchell A Ellena, Daniel J. Tomcheck, Jack J. Glennon

Publication number: 20250065461Abstract: A power tool comprising a power tool housing and a motor within the power tool housing. The motor including a rotor and a stator, the rotor coupled to a motor shaft to produce a rotational output. The power tool further includes a sensor within the power tool housing, the sensor configured to sense a free fall of the power tool, generate an output signal related to the sensed free fall. The power tool further includes a controller including a processor and a memory, the controller configured to receive the output signal from the sensor, detect the free fall of the power tool based on the output signal from the sensor, and brake the motor when the free fall of the power tool is detected.Type: ApplicationFiled: September 16, 2024Publication date: February 27, 2025Inventors: Joseph G. Bloomfield, Arik A. Miller, Daniel J. Tomcheck

Publication number: 20240258941Abstract: Systems and methods for braking a power tool using a stamped brake resistor. The power tool includes a motor, a trigger configured to be actuated, and a brake switch coupled to the motor. A brake resistor assembly is selectively coupled to the motor via the brake switch and includes a stamped brake resistor. The stamped brake resistor includes a terminal portion and a resistive portion. The resistive portion includes a planar serpentine path. A controller including an electronic processor and a memory is coupled to the trigger, the motor, and the brake switch, and is configured to control power delivered to the motor based on a position of the trigger, determine to brake the motor during operation of the motor, and activate, in response to determining to brake the motor, the brake switch to connect the stamped brake resistor to the motor.Type: ApplicationFiled: February 12, 2024Publication date: August 1, 2024Inventors: David Rose, Daniel J. Tomcheck, Vincent M. Zornow

Publication number: 20240100732Abstract: 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.Type: ApplicationFiled: September 26, 2023Publication date: March 28, 2024Inventors: Peter Roloff, James C. Sitter, Leonard F. Mikat-Stevens, Eric K. Farrington, Jack Glennon, Daniel J. Tomcheck, Caleb M. Schober, David Hoffman
