ELECTRIC MACHINE FOR A VEHICLE POWERTRAIN |
| 摘要 |
An electric machine is provided that includes a rotor assembly having a rotor core configured to support permanent magnets spaced around the rotor core to define a number of rotor poles. The rotor core has multiple rotor slots arranged as multiple barrier layers at each of the rotor poles. The rotor core is configured so that the electric machine satisfies predetermined operating parameters. In one embodiment, the electric machine is coupled with an engine through a belt drive train and provides cranking (engine starting), regeneration and torque assist modes. |
