AI Technical Summary
Technical Problem
Medium and low speed maglev vehicles have high levitation energy consumption, and the levitation electromagnets have high temperatures during operation, which affects their service life.
Method used
The system adopts an M-shaped rail and a T-shaped track beam structure. The levitation electromagnet is located below the M-shaped rail, and the traction motor stator is arranged on the same side as the levitation electromagnet to generate a common normal force to share the load. Combined with water-cooled plates for heat dissipation, the levitation energy consumption is reduced.
Benefits of technology
It reduces levitation energy consumption, extends the service life of levitation electromagnets, and improves the vehicle's load-bearing capacity.

Abstract
This utility model discloses an electromagnetic support system for medium- and low-speed maglev vehicles and a maglev vehicle. The electromagnetic support system includes an M-shaped rail, a levitation electromagnet, and a traction motor stator. The M-shaped rail includes a main body and a secondary induction plate of the traction motor fixed to the middle of the lower surface of the main body. The upper surface of the main body is fixedly connected to the lower surface of the T-shaped track beam. The levitation electromagnet is located below the M-shaped rail and installed on the lower part of the suspension frame support arm of the vehicle body. The levitation electromagnet includes a U-shaped iron core and an electromagnet winding wound around the middle of the U-shaped iron core. The two ends of the U-shaped iron core point upwards toward the main body of the M-shaped rail. The traction motor stator is fixed above the electromagnet winding and corresponds to the position of the secondary induction plate of the traction motor. This utility model is beneficial for reducing the levitation energy consumption of medium- and low-speed maglev vehicles with a vehicle-rail-hugging design and for extending the service life of the levitation electromagnet.
