Fig.2 Motor efficiency in various speeds

Motor efficiency in various speeds


Because spread and display this picture, there is a case to look coarse.

Fig.2 shows measured motor efficiency in various speeds. It achieved higher efficiency than 90 percent in almost all measured point. It is much higher than a former induction motor’s efficiency. It can cover almost all operating region with over 90 percent efficiency. It will be very helpful to the fuel economy of the hybrid truck system.
