Example Embodiment

[0019] Figure 2 is a schematic diagram of an embodiment of the present invention. As shown in Figures 2a and 2d, the primary 3 including the laminated core 31 and the winding 32 embedded in the core slot is arranged on both sides of the lower part of the car body. The surface of the primary 3 of the linear induction motor faces upwards, and the two sides of the rails face downwards. The track surface of the primary motor 3 is provided with a steel plate 5 with good magnetic permeability, and a long secondary reaction plate 4 made of aluminum or copper is laid on the steel plate.

[0020] As shown in Fig. 2b, the present invention is provided with a suspension device 25 for placing linear motors on both sides of the lower part of the vehicle body, and the suspension device 25 is an aluminum alloy box structure. The primary 3 of the linear motor including the iron core 31 and the winding 32 is arranged on the suspension device 25 on both sides of the lower part of the vehicle body, ...
