Abstract:

© 2018 IEEE. Both torque winding magnetic field and suspension winding magnetic field induce currents in the rotor in conventional bearingless induction motor (BIM). Owing to the induced currents of suspension winding magnetic field, the airgap magnetic field is affected that can result in the error of radial suspension forces. To overcome such drawbacks, a novel BIM with fixed-pole rotor is proposed, which is called bearingless fixed-pole rotor induction (BFPRI) motor. First, the structure of BFPRI motor is designed and introduced. Then, rotor currents and radial suspension forces are calculated and compared with conventional BIM. Finally, the prototype motor equipped with fixed-pole rotor is constructed. In this novel motor, only the torque winding magnetic field will induce currents in the rotor, which makes the precision of radial suspension forces higher and reduces the complexity of BIM control system. Analytical results are validated through finite element analysis (FEA) and experimentation.
