| Zusammenfassung: | An electric machine includes a rotor having at least one pole pair, the at least one pole pair including a first magnetic pole and a second magnetic pole having opposite polarities. The first magnetic pole may include a first inner radial permanent-magnet layer and a first outer radial permanent-magnet layer. The second magnetic pole may include a second inner radial permanent-magnet layer and a second outer radial permanent-magnet layer. An outer end of the first inner radial permanent-magnet layer and an outer end of the second inner radial permanent-magnet layer may be separated by an angle of between about 27 and about 55 electrical degrees. The electric machine may also include a stator having a stator core with an odd number of stator slots per pole pair of the rotor. |
