摘要： A DC motor having a ring stator slotted on the inside and outside surfaces to receive insulated square iron wire windings to form a stationary armature, the windings being connected at a plurality of taps thereon to a stationary commutator for creation of a rotating magnetic field. A rotating brush holder, driven by an external motor cooperates with the stationary commutator to effect the rotating magnetic field, DC voltage being applied to the brushes by way of a slip ring arrangement. A bipolar field structure is rotatably mounted inside the armature ring and is continuously energized in one polarity for reaction with the armature by another slip ring and brush arrangement.

摘要： A direct current constant torque adjustable speed motor having a stationary armature and revolving field structure, which through a self-propelled adjustable speed governor drives a revolving brush holder to produce magnetic field rotation in the armature. Iron windings are employed in both the armature and field to provide sufficient resistance to current and to minimize induced EMF''s. The speed governor is of the centrifugal friction drum type and in two embodiments may be present or adjustable during motor rotation.
