Field-oriented control drive circuit design

Abstract

Field-oriented control drive circuits, as a new type of control method recently, are different from the traditional control principle of electronic speed controllers and have gradually started to be used in large numbers in recent years. The correct design of the circuit and the implementation of the algorithm to realize precise control of the brushless motor is a question worth investigating. The research purpose of this paper is to design a field-oriented drive circuit to drive a brushless motor with the smallest possible size and the largest possible load to improve performance and usability. Based on the current design of the field-oriented control drive circuits, the author has selected the right microprogrammed control Unit and algorithm to improve the practicality and performance of the field-oriented control drive circuits. Finally, a few advantages of this field-oriented control drive circuits are summarized. The conclusion of this research is that the brushless motor can be controlled precisely by a simple operation. However, the cost is that the algorithm design is more complicated.
