  • System and method for kickback detection in a circular saw
    Patent number: 10144148
    Abstract: A method of detecting kickback during operation of a saw includes identifying with a controller in a saw a measured rotational speed of a rotating blade in the saw with reference to signals from a rotational rate sensor, identifying with the controller an estimated rotational speed of the rotating blade in the saw with reference to the measured rotational speed, at least one previously measured rotational speed, and a measurement of a previous change in rotational speed of the rotating blade, identifying with the controller an estimated torque force for a drive shaft of a motor in the saw that rotates the blade with reference to the measured rotational speed, and activating with the controller a blade arrest mechanism in response to a difference between the measured rotational speed and the estimated rotational speed exceeding a first threshold and the estimated torque force exceeding a second threshold.
