Rotor of an electric machine with embedded permanent magnets and electric machine |
摘要 |
A rotor for an electric machine excited by magnetic poles formed by one or more embedded permanent magnets includes a magnetic body and the one or more embedded permanent magnets associated with the magnetic body defining first magnetic poles and second magnetic poles of alternating magnetic polarity along a rotor direction. For at least one of the one or more embedded permanent magnets a rotor segment is arranged between the one or more embedded permanent magnets and a first surface of the magnetic body. At least one retainer element connects the rotor segment to a portion of the magnetic body. |

1. A rotor for an electric machine excited by magnetic poles formed by one or more embedded permanent magnets, comprising a magnetic body and the one or more embedded permanent magnets associated with the magnetic body defining first magnetic poles and second magnetic poles of alternating magnetic polarity along a rotor direction, wherein for at least one of the one or more embedded permanent magnets a rotor segment is arranged between the one or more embedded permanent magnets and a first surface of the magnetic body, wherein at least one retainer element connects the rotor segment to a portion of the magnetic body, wherein the rotor segment and/or at least one of the embedded permanent magnets is locked by the at least one retainer element and fixed in a radial or axial position in the magnetic body, and in that a magnetically non-conductive area is assigned to at least one of the one or more embedded permanent magnets, wherein the magnetically non-conductive area is included in the at least one retainer element. |
