Testing System Of The Brushless DC Motor Controller

The brushless dc motor controller circuit board test system is mainly about a kind of motor controller circuit board to design automatic detection research.In this paper, the study aims to improve the production efficiency of a motor controller circuit board. Based on the research of the brushless dc motor, brushless dc motor control method of research, the study of the working principle of the brushless dc motor controller, gradually build up the hardware composition and software design of the detection system. At present, most of the circuit board test system is still in semi-automatic, on the basis of using artificial for detecting the appearance of the circuit board, the online part of the circuit board function test, so as to determine the defects of circuit board. This design adopts the principle of automatic control, through the design of the comprehensive test bed, greatly increased the degree of automation, improve work efficiency.Based on the principle of brushless dc motor and motor control system model, after fully research put forward a kind of brushless dc motor controller circuit board integrated real-time detection system, and the motor controller test system software and hardware design, and use the LABVIEW the PC analysis software of the test system is developed. The following is an important task of the paper:Firstly, studies the existing working principle of brushless dc motor, brushless dc motor of the basic institutions mainly include: motor ontology, inverter, and position sensor. Its working principle are discussed in(1) winding connection mode,(2)drive mode,(3) conduction mode, and further to establish the mathematical model of brushless dc motor, the research for the design of the controller circuit board test system to provide certain theoretical basis.Secondly, based on MATLAB/SIMULINK simulation model of brushless dc motor system, has carried on the simulation and experiment of the control system.Results show that the model is verified the validity of the mathematical model and the rationality of the control system, data for the controller circuit board test system provides a certain reference.Then, on the working principle of brushless dc motor controller circuit board, focus on analysis it is concluded that the test items and purpose of the integrated testing system. Finally, conceived of overall design, compares the key hardware selection, choose the right function module, controller of brushless dc motor test system hardware circuit design, determine the connection between each function module, drawing the SCH principle of the system hardware circuit diagram drawing.According to the function of the detection system needs to implement in software programming, mainly includes two parts:(1) data acquisition program design,(2) the PC display program design. The data acquisition program design can be divided into:(1) the current data collection, data collection,(2) voltage(3) the temperature data acquisition program design. PC display program using the LABVIEW design, mainly including:(1) the system parameter setting module,(2) the sensor data real-time monitoring module,(3) the system time module,(4) data management module, etc.This article research the brushless dc motor controller circuit board test system for brushless dc motor controller has a certain guiding significance to the detection, is advantageous to the promotion of brushless dc motor used. In the future to further improve the function of the controller test system, to improve the stability of the test system. If in the future, the company’s motor controller, by adjusting the test bed of some hardware accessories, or modify some function program, or adjust the display panel, can adapt to other motor controller circuit board testing requirements.
