摘要

摘 要

本研究的目的是設計與製作3KW無刷直流馬達(BLDCM)的驅動器。由於無刷直流馬達具有高效率及高轉矩的特性，且利用電子電路取代傳統直流馬達的碳刷及整流子，因此在馬達運轉時不會產生火花且擁有高速運轉、噪音小和維護簡易等優點，在環境的使用上和安全性及可靠度等考量上成為取代其他馬達的優勢，使其能被廣泛應用於工業上。本研究以IKCS22F60F2C智慧型高功率模組作為動力的驅動系統以減少整體系統空間，並增加系統的可靠度、安全性和穩定性並達到降低成本和空間的目標。
本驅動器整體架構以德州儀器公司(TI)所生產的TMS320LF2407數位訊號處理器(DSP)為控制核心，控制的方法以傳統的PI(比例-積分)控制法為主，以使馬達在運轉上更為順暢。本研究所製作的電源系統是透過交流220Vac的輸入，經過橋式整流器輸出311Vdc的直流電壓，再利用直流對直流電源變換電路以高頻變壓器和穩壓電路得到多組輸出電壓提供給驅動電路使用，不需再外接多種電壓與電流保護裝置，以此節省整體系統之空間。由於IKCS22F60F2C的內部結構將驅動電路及保護措施都納入其中，使整體電路與架構空間可以縮小，達到系統安全性的提升與降低成本及空間的目的。

Abstract
We design and manufacture a driver in this paper for the 3KW brushless dc motor (BLDCM). The motor can operate in high speed and torque, and use the electronic circuit instead of the carbon brush and commutator of conventional dc motor. Thus, The BLDCM has the advantages, such as high speed, low noise, and easy maintenance, but not the drawback of producing sparks. About the considerations of use, it can replace the other conventional dc motors because it is possessed of the characteristics of safety and reliability in worse environment. Therefore, it can be widely used in industry. In this paper, the IKCS22F60F2C intelligent power module is used as a power drive system to increase the reliability, security and stability of the system, and achieve the purpose of reducing the cost and space. Also, TMS320LF2407 digital signal processor (DSP) made by Texas Instruments is adopted as the algorithm device of control.
The traditional PI (proportional - integral) control rule is used to tune the torque and make the motor run smoothly. The 2200Vac is connected to the input of this power system. Through the bridge rectifier, the bus voltage obtained is 311Vdc. Also, the high-frequency transformer is used to transform the different output voltages providing for the driver circuit. It is not need to add extra device, such voltage and current devices. Thus, it saves the space of the whole system. Because of the IKCS22F60F2C’s internal structure has the drive circuit and protection mechanism, the space and cost in the whole system can be reduced, and the enhancement of the safety is also achieved.
