在磁懸浮系統中,若希望轉子穩定懸浮於磁場中央,則必須主動控制轉子五個自由度,而傳統磁懸浮馬達系統,由於馬達只負責提供轉矩,故必須額外增加兩組徑向磁力軸承以及一組軸向磁力軸承才能使轉子穩定懸浮於磁場中央。自軸承馬達就是將徑向磁力軸承與馬達做結合,使馬達能同時產生轉矩及徑向力。本文提出的自軸承馬達系統共包含一顆自軸承馬達、一組軸向磁力軸承以及一組被動式徑向磁力軸承,故為三軸主動控制系統,雖然穩定性較五軸主動控制系統差,但擁有體積較小、控制容易、成本降低等優點。本文先由有限元素軟體對系統進行分析,包含被動式磁力軸承設計、系統元件擺設位置分析以及系統啟動方法設計等,接著建立了系統原型機,最後以實驗來驗證自軸承馬達系統的性能。

In the magnetic levitation system, to realize non-co ntact magnetic suspension, the rotor must be magnetically stabilized in five degrees of freedom. Since the motor is responsible for generating torque in conventional magnetic levitation system, it needs the additional two radial magnetic bearing and one thrust magnetic bearing to realize non-contact magnetic suspension. Self-bearing motor is a result of the integration of a radial magnetic bearing and a motor, which generate motor torque and radial force simultaneously. This essay proposed a three-axis-controlled bearingless motor system which consists of a bearingless motor, a thrust magnetic bearing and a passive magnetic bearing, although less stability than five-DOF bearingless motor system, it still have the advantage of compactness, easily control and low cost. After the three-DOF bearingless motor system is analyzed by finite element analysis software, the passive magnetic bearing is designed, the system component location is analyzed and the force of system is also analyzed, and finally established the prototype system and verified the performance by experiment.
