This paper presents the development of the single side ironless Halbach permanent magnet linear synchronous motor (PMLSM) for a novel electromagnetic suspension (EMS) maglev vehicle. The basic structure of the propulsion motor and the vehicle are firstly described. Then the thrust and normal force of the ironless PMLSM are analyzed. The configuration of the propulsion system and field oriented control...
This paper establishes a hardware-in-the-loop realtime simulation system of long stator linear synchronous motor (LSM) drive with neutral point clamp (NPC) 3-level AC-DC-AC converter for high speed maglev train. The dynamic model of the LSM supplied by two parallel converters is described in detail. Hardware configuration, simulation algorithms and system model based on dSPACE real-time simulation...
Controlled-PM linear synchronous motor (LSM) is a potential structure type for levitation system. Although the levitation and propulsion is controlled independently, they may influence each other. The change of gap-length may worsen the propulsion performance and the d-axis current may aggravate the levitation load. This paper presents a decoupled control for thrust and lift force, and a vehicle-loaded...
