SPEED RAMP-UP CONTROL METHOD IN POWER TOOL, POWER TOOL AND SYSTEM

A method of operating a power tool (10) having a motor (100) and a controller (232) during a start-up period of the power tool (10), the start-up period having a plurality of intervals is provided, the power tool (10) receiving electric power from a removable battery pack (16). The method includes:...

More Information
Summary:A method of operating a power tool (10) having a motor (100) and a controller (232) during a start-up period of the power tool (10), the start-up period having a plurality of intervals is provided, the power tool (10) receiving electric power from a removable battery pack (16). 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 (10) from the battery pack (16) 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 (100). A power tool (10) and a system configured to carry out said method.
