摘　　要：矢量控制理论解决了交流电动机电磁转矩的有效控制,双闭环矢量控制策略提高了同步电动机变频调速系统的动态性能。介绍稀土永磁同步电动机(转子无阻尼绕组)设计和自控式变频调速,典型规格样机实测数据表明具有转矩和转速平稳、同步调速范围宽的优点以及工程实用性。The vector control theory solved electric magnetic torque effective control of A. C. motor, the system dynamic performance of synchronous motor speed adjustment when varying frequency is improved by double-loop Vector control stratagem. This paper introduces REPMSM （no-damping windings in the rotor） design and the speed adjustment through varying frequency by vector control of self-control, the real measured data of the sample motor verify advantages such as smooth torque and wide speed adjusting range and engineering practicability.
