| 摘要 |
The invention relates to a method and a device for magnetizing magnetic material pieces (13A, 13B, 13C) of a rotor (5) in a synchronous machine, in particular hybrid synchronous machine (1),as well as a rotor (5). In the method, the magnetic material pieces (13A, 13B, 13C), which are embedded in the rotor (5) and which are originally unmagnetized, are magnetized by means of the use of a magnetization coil (17) of a magnetization device (18). Provision is made,in the vicinity of the magnetic material pieces (13A, 13B, 13C),for closed hollow spaces (15A, 15B, 15C), which can only be accessed in axial direction, for simplifying the assembly and for shortening the magnetization clock times in the rotor (5). The magnetization of the embedded magnetic material pieces (13A, 13B, 13C) into permanent magnets (13D, 13E, 13F) of the preassembled rotor (5) is carried out by means of at least two or more magnetizing magnetization coils (17), which are at least partially inserted into the hollow spaces (15A, 15B, 15C). The magnetization coils (17) are preferably separated. |
