| dc.title | Development of doubly-fed electric motor and its application | en_US |
| dcterms.abstract | Electric motors are by far the most efficient and the most environmental protective solution for vehicles power system. The advantages of electric motors are obvious. Firstly, they have relatively higher efficiency than conventional diesel motor which don’t release any poisonous gas to atmosphere. Besides, the internal structure of motor is simple which requires less maintenance cost. There are by far numerous design of motor such as synchronous motor, servo motor, stepper motor, switching reluctance motor and doubly-fed motor, etc. Among these, doubly-fed electric motor has good flexibility of parameter adjustment like power factor, operation speed, so on and so forth. Besides, doubly-fed motor doesn’t have slip ring which highly reduce the maintenance costs than the motors with slip rings. In this paper, automobile dynamics will be discussed to find out the design discipline for Brushless Doubly-fed Electric Motor (BDFM) such as air resistance, rolling resistance and slope resistance. With these requirements, ANSOFT Maxwell is used to simulate motor operation. As the parameters of BDFM like radius, pitch and tank area vary, the performance of motor will change. With results analysis, the design strategies of parameters for electric vehicles will be discussed. | en_US |
