Abstract
A motor is disclosed that has the capability of detecting the rotary motion of the motor and to generate electrical signals that are indicative of the speed of operation of the motor. The motor has a magnet that is embedded within the molded resin of the commutator or other parts of an armature and a Hall effect sensor is positioned in close proximity to the rotating magnet to thereby provide an electrical signal that is proportional to the rotating speed of the motor.
