Abstract
An electric motor has a unitary frame. The frame includes locating structure extending from an end portion thereof. The motor includes a shaft and an armature disposed within at least a portion of the frame and constructed and arranged to rotate the shaft. A commulator is associated with the shaft. Windings are carried by the armature and connected to the commulator. Permanent magnet structure is carried by the frame and is disposed generally adjacent to the armature. At least one brush arm is coupled to an associated locating structure. A brush is coupled with an associated brush arm so that the brush engages the commutator to deliver electric current to the windings. A structure, containing iron, is disposed about at least a portion of the permanent magnet structure to define a flux path for the motor.
