20100072864 | Motor Assembly with Sensor Target on Motor Rotor and Method of Forming Same - A motor assembly is provided that includes a rotor having a plurality of coaxial rotor laminations, a conductive end ring adjacent the rotor laminations that establishes an axial end of the rotor; and a target member supported by the end ring and rotatable with the rotor. A sensor is operable to monitor, for example, speed and/or angular position of the target member as the rotor rotates. A method of forming a motor assembly includes providing a sensor target and a sensor operable to determine the position of the sensor target. The method includes connecting the sensor target with a motor rotor end ring such that the sensor target is supported by the motor rotor end ring for common rotation therewith and may be sensed by the sensor. Connecting the sensor target to the end ring may be by overcasting the sensor target onto the motor rotor end ring. | 03-25-2010 |
20100102666 | METHODS AND APPARATUS FOR AN ELECTRIC MACHINE WITH A CAST ROTOR - A squirrel cage rotor structure used in connection with an electrical machine is formed from a high-strength, high-conductivity, and heat-treatable aluminum alloy, e.g., a T61 tempered aluminum alloy, such as A6101-T61. The resulting structure has improved strength compared to conventional pure aluminum structures, while at the same time limiting the reduction in electrical conductivity. | 04-29-2010 |

The resolver includes a stator core, a plurality of wire windings operatively connected to the stator core, a winding support between the windings and the stator core, and a cover at least partially enclosing the windings. One of the cover and the winding support defines a pin that is fittable inside a hole in the second member. The pin functions as a locating feature, which ensures that the stator is accurately mounted to the second member. Because the pin is part of the winding support or the cover, the locating feature does not entail the use of an extra part, thereby simplifying assembly of the stator. | 07-14-2011 |
