Abstract
An electronic module is provided for a power tool having an electric motor. The module includes a printed circuit board (PCB) having a first surface and a second surface; first set of power switches mounted on the first surface of the PCB; second set of power switches mounted on the PCB and electrically coupled to the first power switches forming an inverter bridge circuit for driving the electric motor; a first heat sink surface-mounted on the first surface of the PCB and having a planar main body disposed over the first power switches; a module housing arranged to receive the PCB therein; and a second heat sink secured to the module housing in thermal communication with the first heat sink to transfer heat from the first power switches.
