Abstract
An electronic module is provided for a power tool having an electric motor. The module includes a module housing having a radial portion and a cylindrical portion extending from the radial portion away from the electric motor and defining an open end, a printed circuit board (PCB) received within the module housing through the open end thereof, power switches mounted on the PCB, and magnetic sensors mounted on the PCB facing the motor substantially equidistantly from a center of the PCB. The module housing includes openings disposed in the radial portion angularly around a center of the module housing to receive the magnetic sensors therein to allow the magnetic sensors to magnetically interface with the electric motor.
