BLDC?s speed performance has the characteristics of DC motors, and it is also has small volume, light weight, high efficiency and no excitation loss advantages. BLDC also has the advantages of AC motor, such as simple structure, reliable operation, convenient maintenance, etc…Therefore, BLDC had been using in the wide range fields of national economy, such as medical equipment, instrumentation, chemical, textile, household appliances and office automation. The control requirements of high reliability, such as fast response speed, high precision, small size. Based on MCU chip control system is generally difficult to realize this requirement. And, the cost of control system based on DSP chip is generally too high. However with all kinds of Brushless DC motor control method is being more and more mature, especially the largescale field programmable gate array FPGA, CPLD appeared, provides the possibility to realize these requirements. This topic is proposed on the basis of this background. This paper presents a brushless DC motor controller based on CPLD . Focus on the analysis of the hardware controller and its working principle. And I have pleted the design of PCB controller. According to the control task the controller had, a controller algorithm was proposed. And finally, using Simulink simulation verified that the proposed control algorithm.
