切換式磁阻馬達係利用磁阻轉矩來運轉，轉子不需要永久磁鐵，無退磁問題，也無轉子發熱問題，且具有低成本、高效率、高穩定性、高散熱性之優點，但是由於雙凸極結構，造成磁路非線性，以致轉矩控制不易，故在發展初期被認為控制難度極高的馬達；近年來，電力電子設備與微處理器快速發展，工程師與研究人員已逐步克服各種軟硬體上之困難，使得切換式磁阻馬達的潛力能有所發揮，進而可與感應馬達、直流馬達以及交流馬達等作為調速系統動力源之馬達相抗衡，在高能量密度、高溫度且惡劣環境下，更能顯示其優勢，故已逐漸引起工業界及學術界的研究興趣。

本文應用具浮點運算功能之32位元數位信號處理器並搭配週邊電路完成切換式磁阻馬達驅動系統之實作；最後於個人電腦上以圖控式語言設計一即時監控人機介面，對切換式磁阻馬達驅動系統進行電壓、電流、轉速之監控。

The reluctance torque of switched reluctance motor could drive the rotor directly. Rotor doesn’t need to be made from permanent magnet and the demagnetization and heat emission problems can be avoided. There are also a lot of advantages, such as the low cost, high efficiency, high stability and high hot emission, make it very attractive to the engineers and researchers. The dual-flange-pole rotor structure will induce non-linear magnetic filed in the air gap between armature and rotor, so the reluctance torque is not easy to handle. The switched reluctance motor is considered hard to control at the early stages of development. In recently years, with the rapid improvement of power electronic devices and microprocessor chips, the engineers and researchers pay more attentions to overcome the difficulties encountered in both the software and hardware step by step. It can now exert the motor’s capability to contend with the inductor motor and the alternating current motor. Furthermore, it is more advantageous than others in the high energy density, high temperature and adverse circumstances. It has obviously caught caused the industry’s attention and the academia''s research interests.
The work of this is to design and develop a drive system for the switched reluctance motor drive system by using the 32-bit floating point Digital Signal Processor, and operate it in coordination with the peripheral circuits. Finally, the study will integrate the graph control programming to design a monitoring and control system with Man-Machinery Interface (MMI) for monitoring voltage, current and speed of the switched reluctance motor drive system.
