Abstract

A power tool including an electric motor is provided. The tool includes a substantially disc-shaped printed circuit board (PCB), power switches mounted on the PCB; magnetic sensors mounted on the PCB facing the motor; a heat sink in thermal communication with the power switches disposed between the PCB and the electric motor; and a molded casing structurally securing the heat sink relative to the PCB. The molded casing includes a center opening, at least one first opening provided at a first radial distance from the center opening arranged to receive the magnetic sensors therein, and at least one second opening provided at a second radial distance from the center opening arranged to securely receive the heat sink therein.
