Design of permanent magnet synchronous motor for parallel hybrid electric vehicle
Abstract With the energy crisis and environmental problems of the world are becoming more and more serious, the automobile energy saving and environmental protection performance has gained more and more attention, all the countries in the world and the major automobile manufacturers have invested heavily in hybrid electric vehicle. The advantages of hybrid fusion of traditional cars and electric vehicles, has the advantages of high energy utilization, energy diversity, environmental protection and other advantages, become solve the feasible measures of energy saving and environmental protection. Auxiliary power unit is the key part of hybrid electric vehicle energy saving and emission reduction, and the permanent magnet synchronous generator is the core component. Therefore, this paper will start from the requirements of hybrid vehicle generator, the parallel hybrid electric vehicle is started with the design of permanent magnet synchronous generator.
In the first part, the background, purpose and significance analysis of permanent magnet synchronous generator, current status of research on permanent magnet synchronous generator at home and abroad, the current situation and advantages of rare earth permanent magnet synchronous motor, clear the content, to further clarify the rare earth permanent magnet synchronous motor design necessity.
Then introduced the hybrid vehicle classification and various hybrid vehicle characteristics, basic structure, working mode, working mode and working principle. And then through the representative of all kinds of automobile and introduces the structure and working process, a preliminary understanding of the hybrid electric vehicle, the advantages and disadvantages of comparison of three kinds of structure are selection.
Secondly, analyzes several structure of rotor and its advantages and disadvantages, the classification and characteristics of the permanent magnetic materials, as well as the advantages and disadvantages of various materials. Through the calculation formula and empirical formula, estimate the size of the motor preliminary design and determine permanent magnet material.
Thirdly, this paper mainly designs 10kW permanent magnet synchronous generator what is used to start the generator，introduces the operation steps of the steady-state and transient ansoft maxwell software. It also observed the groove, the motor stator winding arrangement, built-in radial rotor, motor, magnetic clouds map of two-dimensional model.
Finally, analysis of motor permanent magnet size, air gap size, copper wire of diameter and conductor per slot respectively, the output power of generator and motor efficiency and other properties, we get the optimum results. Then the simulation the motor load torque, in the case of transient and transient EMF, flux curve and in the state of motion under the magnetic field lines, magnetic flux, magnetic cloud chart.

Key words hybrid electric vehicle, parallel, permanent magnet synchronous generator, Ansoft, motor design
