OVERLOAD CONTROL FOR A POWER TOOL

Power tools including a housing, a motor, a power circuit supplying operating power to the motor through a triac, a speed sensor configured to detect a speed of the motor, a speed selector, and an electronic processor. The electronic processor is configured to determine a selected speed and set a present conduction angle of the triac to an initial conduction angle corresponding to the selected speed. The electronic processor is also configured to determine whether the speed is decreasing and determine whether the present conduction angle is below a maximum conduction angle corresponding to the selected speed when the speed is decreasing. The electronic processor is further configured to increase the present conduction angle when the present conduction angle is below the maximum conduction angle and maintain the present conduction angle at the maximum conduction angle when the present conduction angle is at or above the maximum conduction angle.
