Abstract

The levitation electromagnet is the core component for providing levitation force in high-speed maglev trains. This paper proposes a novel structure and power supply scheme for suspension electromagnets, where the coil is split into a regulating coil (connected to a controller) and a constant-current coil (supplied by a constant-current source). First, the circuit, magnetic circuit, and internal heat transfer models of the electromagnet are established to analyze its power loss, electromagnetic force, and temperature characteristics. Then, the coil turns and supply current are optimized with the maximum electromagnetic force-to-power ratio as the objective. Finally, a finite element model is constructed to compare the proposed electromagnet with the conventional one, verifying the feasibility of the novel structure and power supply scheme. This study provides a reliable reference for the design and optimization of high-speed maglev suspension electromagnets.
