| 20110241597 | H-BRIDGE DRIVE CIRCUIT FOR STEP MOTOR CONTROL - A drive circuit for step motors with bifilar windings is provided in which both parallel and series winding configurations for the stator coils are selectable by a motor controller based on the motor speed. For low speeds a series configuration is selected, while for higher speeds a parallel configuration is selected. Dynamic torque is optimized by the selection for more efficient motor operation with less drive current. | 10-06-2011 |
| 20110037352 | MOTOR END CAP POSITIONING ELEMENT FOR MAINTAINING ROTOR-STATOR CONCENTRICITY - A motor is provided with a set of end cap guides on the ends of a stator winding assembly to plot the placement of end caps into the correct placement relative to the stator winding assembly so that the rotor assembly is maintained concentric with the stator. The end cap guides may be rings fitting within the winding insulators on the ends of the stator stack or may be integrated as guide segments with the winding insulators to outline an interrupted cylindrical inner surface coinciding with the inner diameter of the stator winding assembly. The guides allow proper positioning of the rotor assembly without increasing the stator stack length. | 02-17-2011 |
