  • SPEED RAMP-UP CONTROL IN POWER TOOL
    Publication number: 20240333188
    Abstract: A method of operating a power tool having a motor and a controller during a start-up period of the power tool, the start-up period having a plurality of intervals is provided. The method includes: initializing a current clipping threshold to a baseline value, applying the current clipping threshold to the electrical current drawn by the power tool from the battery pack during a first interval of the plurality of intervals, and gradually increasing the current clipping threshold over subsequent intervals of the plurality of intervals to control a ramp-up curve of the rotational speed of the motor.
