Secondary iron core geometry: BYDRecent Research Landscape

Magnetic flux leakage in linear motors causes propulsion inefficiency and vibration during high-speed transit. Precision engineering of the secondary core structure stabilizes the electromagnetic suspension to maintain constant air-gap clearance.

What technical problems is BYD addressing in Secondary iron core geometry?

Parasitic vibration and instability

(60)evidences

Inherent mechanical vibrations and electromagnetic fluctuations in linear propulsion systems cause ride instability. Mitigating these disturbances ensures passenger safety and structural integrity in high-speed transport.

Parasitic magnetic drag

(48)evidences

Unwanted mechanical oscillations and noise in linear motion systems. Reducing these disturbances improves ride quality and structural longevity in suspension and vehicle applications.

Insufficient electromagnetic propulsion force

(32)evidences

Inadequate lift and propulsion efficiency in linear motor systems. Overcoming this limitation ensures stable vehicle suspension and high-speed motion control.

Insufficient magnetic flux density

(29)evidences

Inadequate magnetic coupling between excitation assemblies and suspension components limits force production. Optimizing this density ensures reliable vehicle levitation and propulsion efficiency.
