Abstract:
A method of detecting and mitigating kickback in a saw includes identification of a running average speed (RPM) of a saw blade, the speed at a given time sample relative to the running average speed, the percentage change in speed from one speed sample to the previous speed sample, and the percentage change in average speed based on the current speed of the saw blade. If the identified speed profile from the samples indicates a kickback is imminent, then the saw identifies an imminent kickback event and removes power from the saw motor to mitigate kickback.
