Title The controller design of the model Brushless DC motor
Abstract
In recent years,the brushless DC motor has been used more and more widely in the field of motor,because the brushless DC motor has the advantages of high efficiency,small noise,large starting torque and other advantages.The motor controller just works as the core of the control，and its operation efficiency and stability has been paid more and more attention.In this paper,my goal is to design the corresponding controller which is based on a company's new brushless DC motor .
Firstly,this paper designs the position sensor installation with the use of corresponding program and the hardware control circuit which is mainly composed of the single-chip microcomputer.This design is according to the normal characteristic of conventional brushless DC motor controller and the new characteristic of new brushless DC motor model.And then this paper introduces the peripheral circuit, power circuit, protection circuit as the main elements of logic.
Second , as for the software part,this paper discusses the overall design and gives the flow chart of the program firstly,then design and gives the control code.
Finally, this paper will have the idle test based on the electric motor and its control system，and analyze whether the controller and program design is reasonable or not according to the experimental results.
