论变频器控制永磁同步电机的理论和实践

Discussion on Theory and Practice of Permanent Magnet Synchronous Motor Controlled by Frequency Converter

本文从永磁同步电机的原理、结构和数学模型出发、同时阐述施耐德变频器控制永磁同步电机的模型和控制机理,并就施耐德新一代重磅推出的御卓系列ATV340变频器为实例,以此来论述变频器分别以开环和闭环电机控制方式来驱动永磁同步电机的原理和实践调试方法。并对施耐德变频器控制同步电机的实际效果进行客观评估,实践调试方法注意事项的分享以及新老产品的性能比较。

In this paper, the principle, structure and mathematical model of permanent magnet synchronous motor are introduced. At the same time, the model and control mechanism of Schneider frequency converter control permanent magnet synchronous motor are expounded, and the new generation of Schneider Altivar Machine ATV340 is given as an example. This paper discusses the principle and practice of the permanent magnet synchronous motor driven by open-loop and closed- loop motor control respectively, and makes an objective evaluation of the actual effect of Schneider inverter control synchronous motor, the sharing of practice notes and the comparison of performance between old and new products.
