| 发明名称 | Magnetizer for electrical machines | ||
| 摘要 | The present invention relates a device for magnetizing a rotor of an electrical machine with a power rating of at least 1 MW, wherein the rotor comprises permanent magnet material, said device comprising a yoke with an electromagnetic coil arranged to produce a pulsed magnetic field for magnetizing the permanent magnet material, wherein the magnetic field is sufficient to magnetize a permanent magnetic pole wherein the rotor and yoke is in a fixed relation to each other. The invention also relates to a method for magnetization of a rotor with permanent magnets for an electrical machine. | ||

| 主权项 | 1. A device for magnetizing a rotor of an electrical machine, wherein the rotor comprises permanent magnet material, said device comprising: a yoke with an electromagnetic coil arranged to produce a pulsed magnetic field for magnetizing the permanent magnet material, wherein the magnetic field is sufficient to magnetize a permanent magnetic pole, and wherein the rotor and yoke are in a fixed relation to each other when the electromagnetic coil is producing the pulsed magnetic field; and a rotor nest arranged on the yoke, wherein the rotor nest is arranged between the yoke and the rotor. | ||
