Design for Permanent Magnet Synchronous Machine
of Series Hybrid Electric Vehicle
Abstract Nowadays, in order to solve two major problems of environment pollution and energy reduction. The whole countries have invested a huge amount of manpower , material and financial resources and seek effective solutions actively around the world. In the automotive industry, hybrid electric vehicle has emerged that technology is relatively mature currently. Compared with the conventional engine vehicles, the engines often work in the best conditions, and effectively reduce the emissions and improve efficiency. Meanwhile, at the case of the use of electric mode , in certain areas , it can help achieve zero emissions. Therefore, hybrid electric vehicle has both excellences, and it is widely used in the application
In addition, permanent magnet synchronous machine with the advantage of the simple structure, high efficiency and high power factor has become the most advantageous motor type of the hybrid electric vehicle drive motor currently, and has a broad application prospects.
This paper around introducing the series hybrid electric vehicle and calculating permanent magnet synchronous machine and analyzing structure affect for the performance, carries out the following contents:
Firstly, Introducing hybrid electric vehicle development background and significance, and the status of hybrid electric vehicle development at home and abroad in recently, and the composition principle and working principle of the SHEV、PHEV、PSHEV. Meanwhile , the work focuses on the structure and characteristics of series hybrid system.
Secondly, A brief introduction for the structure of permanent magnet synchronous machine、and permanent magnet、and giving out main dimensions formula for permanent magnet synchronous machine, At the same time, based on the Ansoft Maxwell 15，and designing the permanent magnet synchronous machine of the rated power 55kW , and calculating its specific parameters , and listing simple operation steps .
Finally, Based on the software, the calculation date for the rated power 55kW of permanent magnet synchronous machine is optimized, for example, the air gap size, line size and conductor per slot, the width and thickness of permanent magnet in the magnetized direction , and explaining the simulation results.
