Patent number: 11919129Abstract: A power tool and method of detecting impacts of a power tool that includes a motor driving a hammer to impact an anvil. A motor control unit is configured to determine a motor characteristic indicative of a speed of the motor. When the motor characteristic indicates that the speed of the motor is below a speed threshold, the motor control unit employs an acceleration-based technique to detect a first impact based on a change in motor acceleration and generate a first impact indication in response to detecting the first impact. When the motor characteristic indicates that the speed is above the speed threshold, the motor control unit employs a time-based technique to detect a second impact based on an elapsed time and generates a second impact indication in response to detecting the second impact.Type: GrantFiled: October 6, 2022Date of Patent: March 5, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Alex Huber, Matthew Wycklendt, Matthew Mergener, Cole Conrad, Wing Fung Yip

Publication number: 20240034379Abstract: Respective electric drive motors (13a, 13b) drive left and right drive wheels (10a, 10b) having friction brakes, including an electromechanical service brake (31a, 31b) and an auxiliary brake (32a, 32b) mechanically biasing them to a braked state. An elongate handlebar (16) for user control is mounted via a pair of force-sensing couplings (17a, 17b) including a resilient member (18) and a load sensor (19) sensing forces applied by a user to the handlebar and transmitting respective load signals. A controller (37) receives the load signals and controls a current applied to the electric drive motors (13a, 13b) so as to amplify the force sensed by the force-sensing couplings and to generate a torque proportional to a force applied by the user to the handlebar and to actuate an electric release actuator of the auxiliary brake (32a, 32b) when the force applied by the user to the handlebar exceeds a threshold.Type: ApplicationFiled: August 11, 2022Publication date: February 1, 2024Inventors: Wing Leung Chow, Wing Fung Yip

Publication number: 20210078151Abstract: A power tool and a method of operating a power tool including a motor, a clutch collar including a plurality of settings, a wireless transceiver operable to form a wireless connection with a remote device, and a processor coupled to the clutch collar and the wireless transceiver. The processor receives, via the wireless transceiver, a mapping including a plurality of torque levels corresponding to the plurality of settings. The processor detects that the clutch collar is set to a setting of the plurality of settings. The processor is further determines the torque level for the setting from the mapping and detects, during the operation of the power tool, that a torque of the power tool exceeds the torque level. The processor is also configured to generate an indication that the torque exceeds the torque level. The indication may include flashing a light, ratcheting the motor, and stopping the motor.Type: ApplicationFiled: November 30, 2020Publication date: March 18, 2021Inventors: Alex Huber, Carl Benjamin Westerby, Daniel Robert Ertl, Matthew Wycklendt, Matthew Mergener, Mark Alan Kubale, Cole Conrad, Wing Fung Yip
