Coaxial Planetary
Integrated Reducer
Mass-Produced in China First
The third company worldwide - and the first in China - to achieve mass production of coaxial planetary reducers. Lighter, more compact, more efficient: enabling vehicle lightweighting and extended driving range.
Technology-Led. Iterative. Proven.
A signature achievement of Xinke's technology-driven strategy - recognized among Zhejiang Province's first "Single Champion" manufacturing enterprises, with barriers built on materials, structure, and precision.
Ultra-High-Precision Gearing
Grade 4 precision, 21,000 rpm max input speed, 5,200 N·m peak torque. Optimized profile modification suppresses high-speed NVH whine.
Integrated Lightweight Structure
Reducer + differential in one unit with a proprietary magnesium alloy housing: −60% volume, ≈2 kg lighter, −25% structural cost.
Platform-Based Design
One coaxial planetary gear set adapts to single- or two-speed layouts and "3-in-1" drive assemblies across power ranges - shorter OEM development cycles.
Next-Gen Electric Drive Stack
Two-speed AMT with patented shift control, 800V + SiC power electronics, oil-cooled hairpin motor, and in-house energy recovery control.
Your Range, Our Precision.
Five Pillars of the Electric Drive
Coaxial Planetary Integrated Reducer
Material innovation and compact structural design reduce assembly volume and weight while raising transmission efficiency. Acclaimed by leading automakers upon launch; monthly sales have surpassed 20,000 units.
Two-Speed AMT & Shift Control
Independently developed two-speed transmission with smooth shift strategies - filling the domestic mass-production gap, protected by domestic and international patents.
800V Platform + SiC & Hairpin Motor
Electric drive solution for next-generation high-voltage platforms. Line upgrades complete; volume deliveries underway.
Energy Recovery Control Strategy
In-house regenerative braking system with optimized dynamic adjustment logic for higher recovery efficiency.
Intelligent Manufacturing & Full-Chain Validation
Digital production line derived from National Major Science & Technology Project 04, with comprehensive automotive-grade durability validation.
