A Study on Hybrid Power System with Double Rotor Motor
Shi Guangkui,Zhao Hang & Feng QiChina Automotive Technology & Research Center,Tianjin 300162
A novel hybrid power system with a double rotor motor as drive coupler is developed.The prototype test shows that the system can meet all functional requirements of hybrid electric vehicles with low manufacturing cost.The main features of the system are as follows:(1)There is no direct mechanical connection between engine and wheel,so the engine can be adjusted to work at high efficiency zone.(2)The power of the engine can be transmitted to driving axle directly by the electromagnetic force,and only part of power is converted from mechanical energy into electric energy,so the power losses in energy conversion can be reduced.(3)The system can also operate as electronic continuously variable transmission.
