ABSTRACT The researches of this thesis are carried out around the development of high performance machine tool spindle permanent magnet synchronous motor and its drive system. Five parts are included: First of all, concerning the operating characteristics of the machine tool spindle drive system, the optimum current control strategies of spindle PMSM are determined; The design rules of spindle PMSM's key parameters are summarized, based on the study on the influences of the design parameters on the performances of the PMSM operating at different current control strategies; The practical methods to improve the flux-weakening ability of the PMSM are presented; Based on the analysis and comparison of the operating performances of PMSM with different rotor structures, a novel PMSM rotor structure, which is of excellent mechanical performance, suitable for fluxweakening operation and can improve the torque output capacity in the same time, is presented.

本文围绕高性能机床主轴永磁同步电动机及其传动系统的设计研究展开，所做工作主要包括五部分：首先，确定了主轴永磁同步电动机定子电流的最优控制策略；通过对不同控制策略下主要设计参数对主轴永磁同步电动机性能影响的计算研究，总结了参数设计规律；提出了永磁同步电动机弱磁扩速的实用措施；在分析比较不同转子磁路结构电机的性能，尤其是弱磁扩速能力的基础上，提出了一种机械性能优越，易于弱磁扩速，同时能保证电机恒转矩运行时的转矩输出能力的新型转子磁路结构。

The order contact of skeleton is similar to that of common traffic and is suitable to be kept between 1.07 and 1.15. When adopting dynamic stability index to evaluate the high temperature performance of asphalt mixture, it is likely to stretch the work of modified asphalt and there is a discrepancy between the capacity to evaluate different gradation designs and the practical facts. In the late process of creep, stiffness module index can evaluate the high temperature performance of asphalt mixture which is relatively objective. The rutting prediction model based on this is relatively reliable.

采用车辙动稳定度指标评价沥青混合料高温性能时，可能夸大了改性沥青的作用，其对不同级配优劣的鉴别能力与实践事实间也存在一定的差异，而蠕变劲度模量指标能够较为客观地评价沥青混合料的高温稳定性能，且在此基础上建立的车辙预估模型经实践检验具有较高的可靠性。
