碩士 === 國立臺北科技大學 === 電機工程系所 === 98 === Using magnetic bearings supporting motor drive system has zero friction, low noise, high speed, high power and etc. This is current important research for electrical machinery. There are many applications in the Industry, such as spindles of machine tool, turbo molecular pump, grinding and polishing machines, compressors and air conditioners. Self-bearing motor combines of motor and magnetic bearing characteristics of the new motor which uses windings producing motor torque radial force, so the volume of self-bearing motor is small than magnetic bearing motor. The traditional self-bearing motor has suspension windings and torque winding, known as the combined winding self-bearing motor, and running must control these two winding currents. The structure of self-bearing motor stator is constituted by the concentrated winding. Every winding has suspension current and torque current, and the complex winding self-bearing motor is same things produces torque with torque-winding current and radial force with suspension-winding current. In this thesis, a single winding self-bearing motor continue from the previous self-bearing study. Radial force of self-bearing use finite element analysis(FEA) software to Analyze, simulate , verify this force which is correct. Self-bearing is surface magnet motor, 3-phase, 4 poles, 6 slots, rated power 100W and radial force 20 N.
