【摘要】：对两种高效电机——永磁感应电动机和自起动永磁同步电动机进行对比研究。在分析永磁感应电动机结构和工作原理的基础上,结合电动机的数学模型和相关参数,从理论上分析了永磁感应电动机高功率因数及负载能力强的原因。利用有限元方法对永磁感应电动机和自起动永磁同步电动机分别进行了仿真分析,通过比较两种电动机在不同负载下的运行状况来研究电动机的起动能力、功率因数和效率。仿真结果表明,两种电动机均在较宽的负载范围内具有较高的运行效率和功率因数;两者的自起动能力、稳态运行性能各有优劣。阐明两种高效电动机的优缺点,为研究应用提供参考。
[Abstract]:Two kinds of high efficiency motor-permanent magnet induction motor and self-starting permanent magnet synchronous motor are studied. On the basis of analyzing the structure and working principle of permanent magnet induction motor (PMSM), combined with the mathematical model and related parameters of PMSM, the reasons of high power factor and high load capacity of PMSM are analyzed theoretically. The finite element method is used to simulate the permanent magnet induction motor (PMSM) and the self-starting permanent magnet synchronous motor (PMSM) respectively. The starting ability, power factor and efficiency of the two motors are studied by comparing the operating conditions of the two motors under different loads. The simulation results show that the two kinds of motors have higher operating efficiency and power factor in a wide range of loads, and their self-starting ability and steady-state operation performance have their own merits and demerits. The advantages and disadvantages of the two kinds of high efficiency motors are expounded, which provides a reference for the research and application.
