ABSTRACT:
A portable electric motor-driven tool including an electric motor and an electrical control system for controlling the speed of the motor. The control system includes an electric switch for controlling the flow of electrical current to the motor and a composite thyristor and heat sink assembly, with electrical current conducting wires connecting the switch with the assembly. The motor has a fan providing an air stream for cooling the motor. The motor housing has a cavity disposed in the airstream and is configured to receive the thyristor and heat sink assembly and its electrical current conducting wires in quickly detachable relation therein. The heat sink includes an elongated base having laterally extending heat dispersing vanes of various sizes with each vane having a wing portion extending laterally from the vane for added heat dispersement.
