从电磁转矩发生的机制看三大电动机在运动控制系统中之角逐

THE COMPETITION BETWEEN THREE KINDS OF LARGE MOTORS IN THE MOTION CONTROL SYSTEM FROM THE POINT OF VIEW OF GENERATION MECHANISM OF ELECTROMAGNETIC TORQUE

本文首先探讨了电磁转矩发生的机制,然后从电磁转矩d、q系统中的表达式,识别了三大电动机电磁转矩激励因素的耦合程度,从而对比了这些电动机电磁转矩解耦控制的可能性。再在简单介绍了矢量变换控制的思想和实质的基础上,讨论了“在运动控制系统中,采用何种电动机为好的问题。”

In this paper, at first, the generation machanism of electromagnetic torque is investigated , then, from the expression for electromagnetic torque in the d·q axes model, the coupling degree of excitation factor for electromagnetic torgue of three type of Large motors is judged, thereby the possibilities for uncoupled control of electromagnetic torque of these motors are compared with one another, on the basis of making a brief tatrcdution to the idea and method for Transvector control, the problem ' what kind of motors, applied in the motion control system, is fairly good' ?is discussed.
