Excitation motor rotor assembly: BYDRecent Research Landscape

Mechanical instability and electromagnetic losses in high-speed propulsion are mitigated through the precise structural integration of the excitation motor's rotating shaft and rotor components. This engineering control ensures torque consistency and reduces vibration-induced wear in electric vehicle drivetrains.

What technical problems is BYD addressing in Excitation motor rotor assembly?

Excessive powertrain thermal accumulation

(134)evidences

Mechanical interference and positioning errors during the integration of heavy electromagnetic components. Eliminating these errors prevents structural damage and ensures consistent air gap tolerances.

Structural integrity under centrifugal stress

(83)evidences

High-speed rotation causes mechanical deformation and lamination separation in rotor assemblies. Preventing structural failure ensures operational safety and higher power density in electric vehicle traction motors.
