Embodiment Construction

[0034] The present invention as image 3 As shown, it includes iron core 1 and suspension coil 2. This iron core 1 mainly is made up of chip 11, end plate 12, is provided with keyway 14 on the both sides of this chip 11, is also provided with keyway 14 at the corresponding position of both sides of end plate 12 equally, is provided with in this keyway 14 Numerous chips 11 and end plates 12 at both ends are connected into one pin key 13, and an insulating liner 17 is also provided between the pin key 13 and the keyway 14 (see Image 6 ) to prevent the chip 11 from forming a short circuit contact. The shape of this keyway 14 and the pin key 13 cross section that matches with it can be as Pic 4-1 a rectangle (including a square), or Figure 4-2 dovetail, or Figure 4-3 arc at both ends as shown, or any geometry that will ensure a tight fit for the chip. The multiple chips 11 and the two end plates 13 are fixedly connected into one body with screws at both ends of the end pl...

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 invention relates to an electromagnet, in particular to a levitation magnet for a high-speed maglev vehicle and a manufacturing method thereof. Background technique: [0002] The levitation magnet of the high-speed maglev vehicle in the field of constant conduction electromagnetic suspension technology (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. Its The advantage is that the two systems of the driving force (that is, the longitudinal traction force) and the vertical suspension force are combined into one. Even if the train is sucked up and suspended on the track beam, it also moves along the track beam at high speed without contact friction, forming a flight status. As early as the 1970s, Germany launched EMS technology research and developed a series of patented technologies, including patents on levitating m...
