Non-Contact Rotation Test of Lorentz-Force-Type Self-Bearing Motor with Rotational Speed Feedback
2012
Transactions of the Japan Society of Mechanical Engineers Series C
Magnetic bearing motors have the advantages of no friction loss, no lubrication, and so on. However, these motors are not used widely because of their high cost and large size. To overcome these limitations, a self-bearing motor having a simple structure with distributed windings has been proposed. The rotor consists of a permanent magnet and an iron yoke that rotates within the body. The stator consists of a six-phase distributed winding and is installed between the permanent magnet and the
