Implication

This investigation reports on a new powertrain design for maglev cars, indicating its effective propulsion and levitation capabilities.

Key Points

  • The aim is to design and analyze a compact powertrain integrating electrodynamic suspension and in-wheel motor technology for maglev cars.
  • Characterized PMEIM's external magnetic field using analytical and finite element methods.
  • Modeled steady-state electromagnetic force and calculated operating states of the PMEIM powertrain.
  • Conducted electromagnetic design and verified its structure through magnetic circuit analysis.
  • Constructed a prototype for bench testing of non-contact electromagnetic forces.
  • PMEIM powertrain demonstrates effective propulsion and levitation functions.
  • Achieved a propulsion force of 14.2 N under rated conditions.
  • Achieved a levitation force of 45.8 N with a levitation-weight ratio of 2.52.
