Rotor electromagnetic flux geometry: BYDRecent Research Landscape

Inefficient magnetic coupling in high-speed traction motors leads to thermal energy loss and reduced vehicle range. Engineering the specific spatial arrangement of rotor flux paths optimizes torque density and energy conversion efficiency.

What technical problems is BYD addressing in Rotor electromagnetic flux geometry?

Rotor thermal degradation

(113)evidences

Excessive heat accumulation in the excitation unit leads to insulation failure and reduced motor lifespan. Managing thermal loads allows for higher power density and sustained high-torque operation.

Electromagnetic flux leakage

(56)evidences

Inefficient magnetic coupling between stator and rotor components. Reducing these losses increases power density and thermal efficiency in traction motors.
