Rotor for an electric motor
The rotor has a permanent magnetic rotor body attached to a central driveshaft (2), and a casing (8) arranged at a distance to the driveshaft in a radial direction. An annular space is formed between the driveshaft and the casing, where the annular space is formed adjacent to the casing. The annular...

| Zusammenfassung: | The rotor has a permanent magnetic rotor body attached to a central driveshaft (2), and a casing (8) arranged at a distance to the driveshaft in a radial direction. An annular space is formed between the driveshaft and the casing, where the annular space is formed adjacent to the casing. The annular space is partially filled with synthetic magnetic particles (10). The casing is made of metal e.g. stainless steel, and the driveshaft has a magnetic soft ring formed as an iron ring (4). The driveshaft is made of ceramics, and a cover disk (12) is made of metal. An independent claim is also included for a method for establishing a rotor for an electric motor. |
