Abstract
An electronic control unit (ECU) for a motor is mounted to a drum housing or the like in a plane parallel to the plane defined by the surface of the drum housing on which the motor is mounted. The housing for the motor includes an aperture window. Power contacts from the ECU mate with contacts from the motor through the window. Hall-effect sensors attached to the ECU can extend through the aperture to be proximate a ring magnet attached to the armature shaft of the motor. Alternatively, flux guides attached to the drum housing to transmit magnetic flux information from the motor to the Hall-effect sensors. Alternatively, optical sensors attached to the ECU can detect rotations of a reflector ring attached to the armature shaft through the window.
