切換式磁阻馬達是一種結構簡單、堅固、製造成本低廉的電動機。使用直流電源使其驅動電路簡化且可靠,又因為可以控制轉速及轉矩,故速度控制範圍廣,適用於高扭力定功率之場合,所以其應用日漸廣泛。
本文提出一種應用霍爾電流感測器(Current Transducer)及近接感測器(Proximity Sensor)偵測激磁相電流及轉子凸極位置之速度控制器,如此可改善因位置偵測不佳所導致之過換相或欠換相等問題,並且以徳州儀器(TI) TMS 320F240 數位信號處理器(DSP)進行實驗,結果證實本文提出之切換式磁阻電動機應用混合感應器可以有效地降低噪音、進而提升高、低速運轉之順暢度確實可行。
The Switched Reluctance Motor (SRM) inherits a simple and reliable structure with an economical manufacturing cost. The DC power output supplies the unipolar converter to control the pulses sent to SRM. Thus, the velocity and torque are controllable for various velocity commands, and the SRM is gaining more and more applications on high torque requirement field with constant power.
This paper proposes a DSP based hybrid sensor for switched reluctance motor with easy implementation. The current transducer is used to monitor the energized current and proximity sensors for rotor salient. The signals are then fed back to DSP. This design will improve the performance of SRM to operate more smoothly.
