Embodiment Construction

[0034] The invention is like image 3 As shown, the iron core 1 and the floating coil 2 are included. The core 1 is mainly composed of a chip 11 and an end plate 12. There are key grooves 14 on both sides of the chip 11, and the corresponding positions on both sides of the end plate 12 are also provided with key grooves 14. The numerous chips 11 and the end plates 12 at both ends are connected into an integral pin key 13, and an insulating liner 17 is also provided between the pin key 13 and the key groove 14 (see Figure 6 ) To prevent the chip 11 from forming short-circuit contacts. The cross-sectional shape of the keyway 14 and the matching pin key 13 can be rectangular (including square) as shown in Fig. 4-1, or dovetail as shown in Fig. 4-2, or arc at both ends as shown in Fig. 4-3, Or any geometric shape that can ensure that the chip is tightly fixed. Screws are used at both ends of the end plate 13 to fix the chips 11 and the two end plates 13 into one body. The levitation ...

Abstract

This invention relates to suspend electromagnets for high speed magnetic suspend vehicles and their manufactured method, in which, the magnet includes a core and suspend coils characterizing that the chip of the core and an end plate are opened with key slots at the corresponding places of both side edges and pin keys fixedly connecting the chip and the end plates are set in the key slots with an insulation layer set between them and the suspend coil is composed of an internal insulation bush closely adhered to the core and winded to formation on it and excitation coils winded directly.

Description

Technical field: [0001] The present invention relates to electromagnets, particularly to suspension magnets for high-speed maglev vehicles and a manufacturing method thereof. Background technique: [0002] The levitation magnet of the high-speed maglev vehicle in the field of EMS is installed on the bracket at the bottom of the vehicle, corresponding to the long stator of the track. For example, the German TR maglev train is a suction type maglev train. The advantage is that the driving force (ie longitudinal traction force) and the vertical suspension force are combined into one system. Even if the train is sucked up and suspended on the track beam, it also moves at high speed along the track beam without contact friction. Kind of flight status. As early as the 1970s, Germany launched EMS technology research and developed a series of patented technologies. Among them, the patents on floating magnets include: GB2095044A, DE3110339, US4728382, PCT / DE97 / 00294, PCT / DE97 / 00200, etc. ...
