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 about the rotational axis. The power tool includes an electronic processor coupled to the switching network and the movement sensor and configured to implement kickback control of the power tool. To implement the kickback control, the electronic processor is configured to control the switching network to drive the brushless DC motor, receive measurements of the angular velocity of the housing of the power tool from the movement sensor, determine that a plurality of the measurements of the angular velocity of the housing of the power tool exceed a rotation speed threshold, and control the switching network to cease driving of the brushless DC motor in response to determining that the plurality of the measurements of the angular velocity exceed the rotation speed threshold.

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.
