| description | An electronic module is provided for a power tool having an electric motor. The electronic module includes a printed circuit board (PCB) being substantially disc-shaped; power switches mounted on the PCB forming an inverter bridge circuit for driving the electric motor; a controller mounted on the PCB and configured to control a switching operation of the power switches; positional sensors mounted on the PCB substantially equidistantly from a center of the PCB within the control portion and in communication with the controller to provide positional signals related to a rotational position of the electric motor to the controller; and a module housing arranged to receive the PCB therein. The module housing includes a planar portion in parallel to the PCB and openings disposed in the planar portion angularly around a center of the module housing to receive the positional sensors therein. |
