摘要： An electric machine having a stator assembly that includes a stator core and a coil supported by the stator core and a rotor assembly that includes a shaft and a rotor supported by the shaft that is in magnetic interaction with the stator core. The electric machine may include a single sensor configured to detect magnetic polarities of the rotor as the rotor rotates relative to the sensor and to generate a signal representing the detected magnetic polarities of the rotor. The signal and an inverted version of the signal are utilized to control current through the coil. The current may be controlled indirectly by controlling the application of voltage to the coil. The sensor may be encapsulated on a circuit board to positively position the sensor relative to the circuit board. The circuit board may be mounted to a bearing housing of the electric machine. The sensor may be received in a pocket of a bearing housing of the electric machine so the sensor is positively positioned relative to the rotor. The rotor may be connected to the shaft with an encapsulation material. The rotor may be formed as a single cylinder of ferrite. A tapered air gap may be formed between a portion of the stator core and a corresponding portion of the rotor. The electric machine may be a C-frame electric motor with the I-bar portion formed of grain-oriented electric steel.

A first core portion extends along a portion of the axis to define a first core length. The first core portion includes a first reduced back portion that has an inside surface that does not contact the outer surface. A second core portion is coupled to the first core portion for rotation. In some constructions, a coupling member interconnects the shaft, the first core portion, and the second core portion such that the shaft, the first core portion, and the second core portion rotate about the axis substantially in unison.

摘要： An electric drive includes a rotatable shaft, a first drive member, and a second drive member, and is supplied with power from a controller. The controller is operable to supply a first power from a power electronics converter, and a second power that is line power. Supplying the first power individually to the first drive member results in a first shaft speed and first output torque, supplying the second power individually to the second drive member results in a second shaft speed and second output torque, and supplying the first and the second drive members with power at the same time results in a third shaft speed and a third output torque.

摘要： A rotor assembly for an electric motor includes a spoke permanent magnet rotor and a shaft connected thereto. The spoke permanent magnet rotor has an axis of rotation, permanent magnet material, and ferro-magnetic material. The permanent magnet material extends outwardly relative to the axis of rotation to form a plurality of outwardly extending spoke portions of permanent magnet material. The ferro-magnetic material is positioned adjacent to the outwardly extending spoke portions of permanent magnet material. The shaft supports the spoke permanent magnet rotor for rotation about the axis of rotation. The permanent magnet material may circumferentially surround the axis of rotation to form a center portion of permanent magnet material. Further, the axis of rotation may pass through the permanent magnet material. The spoke permanent magnet rotor may be formed using a compaction process and/or an injection molding process.
