Abstract:
Kickback control methods for power tools. One power tool includes a movement sensor configured to measure an angular velocity of the housing of the power tool, and an orientation sensor configured to measure an orientation of the housing. The power tool includes an electronic processor coupled to a switching network and a trigger. To implement the kickback control, the electronic processor is configured to receive measurements of the angular velocity of the housing, receive measurements of the orientation of the housing, determine a binding condition of the power tool based on the measurements of the angular velocity and the measurements of orientation, and control the switching network to cease driving of the brushless DC motor.
