Two speed 3-in-1 E-Drive System
Technical characteristics：
•Highly integrated, compact structure,
easy to match
•Lightweight design with high
torque/weight ratio
•Low harmonic winding and optimal magnetic
pole structure, gear coincident degree ≥ 4.0, better NVH performance
•Hairpin winding with high filling ratio,
high-efficiency bearings, less oil, assembly maximum efficiency reaches 91%
•Synchronizer type two gear structure, the
driving motor of the whole speed section operates in the high efficiency area,
which can achieve higher speed
•High efficiency ball screw shift
mechanism, high precision speed and torque control, smooth shift, shift time
< 500ms
