Abstract
A Brushless Direct-Current (BLDC) motor is provided for a power tool, including a stator comprising a coil, a rotor configured to rotate with respect to the stator, terminals secured to the stator, and a sensor circuit mount attached to the stator. The sensor circuit mount defines a plane having a first side and a second side, the sensor circuit mount including Hall sensors mounted on the first side of the plane of the sensor circuit mount facing the stator. Power-supply lines are secured to the terminals to supply electric current to the coil, the power-supply lines being routed from the terminals without traversing the second side of the plane of the sensor circuit mount. The sensor circuit mount is attached to the stator by at least one fastener that extends through an opening of the sensor circuit mount and a receptacle of the stator.
