Chery Variable Flux Motor

The motor achieves dynamic flux regulation through radial mechanical field adjustment. This technology can significantly improve system efficiency across all operating conditions and extend the vehicle’s range. It is the industry’s first full-speed range flux-adjustable drive motor.

Variable Flux

• Composite rotor structure, mechanical magnetic adjustment
• Hydraulic or electric stepless magnetic adjustment enables smooth flux switching
• Flux optimal control, with a wider high-efficiency region

Energy Efficient

• High-speed active field weakening, iron loss reduction
• Low field-weakening current, copper loss reduction
• The motor CLTC efficiency up to 96.7%, vehicle high-speed range improved by 10%

High Reliability

• Mechanical magnetic adjustment, simple circuit, and reliable structure
• Closed-loop control, real-time detection
• Low back electromotive force, reduced risk of demagnetization
