This paper presents the development of control and power electronics parts for a BLDC motor drive. The signals from the most commonly used sensors for this application are used. The first one is the incremental encoder for speed and relative position detection, the other one is the three-signal Hall sensor which provides information about the absolute rotor position needed for electronic commutation...
Although magnetic bearing motors suffer no friction loss and hence require no lubrication, they are not widely used because of their high cost and large size. To solve these problems, a self-bearing motor having a simple structure with distributed windings is proposed. The rotor consists of a permanent magnet and an iron yoke that rotates in the body. The stator consists of a six-phase distributed...
