Torque and Suspension Force in a Bearingless Switched Reluctance Motor
IEEJ Transactions on Industry Applications, 2004 AbstractBearingless switched reluctance motors, which can control rotor radial positions with magnetic force, have been proposed. The bearingless switched reluctance motors are characterized by integration of switched reluctance motors and magnetic bearings.

Two‐step commutation control of switched reluctance motor based on PWM
The Journal of Engineering, Volume 2019, Issue 22, Page 8414-8418, November 2019., 2019 Aiming at the noise suppression of switched reluctance machine (SRM), the two‐step commutation control method is improved. Combining this with pulse width modulation (PWM), the optimisation problem of the switching angle is studied and analysed and given a method to determine the turn‐on angle, the zero‐voltage turn‐off angle and the turn‐off angle of ...

Lateral Superharmonic Resonance of the Rotor in 12/8 Poles Switched Reluctance Motor
Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018 Switched reluctance motor (SRM) generates a very large electromagnetic radial force when the stator windings commutate because of its doubly salient structure and magnetic saturation. Lateral vibration appears when electromagnetic radial force is applied onto the rotational rotor, which causes continual changes of airgap and further radical ...

Bearingless switched reluctance motor [PDF]
, 2004 A switched reluctance motor has a stator with a first set of poles directed toward levitating a rotor horizontally within the stator. A disc shaped portion of a hybrid rotor is affected by the change in flux relative to the current provided at these ...

IET Electric Power Applications, Volume 18, Issue 12, Page 1703-1718, December 2024.The authors attempt to explore the co‐excitation control method of both radial magnetic bearing (RMB) and switched reluctance motor (SRM) by using a set of asymmetric power converters together in order to reduce the controller cost of conventional magnetic levitation motor systems.

Radial force dynamic current compensation method of single winding bearingless flywheel motor
IET Power Electronics, Volume 8, Issue 7, Page 1224-1229, July 2015., 2015 The position of rotor and stator in switched reluctance motor is exchanged to obtain the single winding bearingless flywheel motor (SWBFM), which is more useful for flywheel energy storage with outer rotor. Compared with the switched reluctance motor, bearingless flywheel motor has obvious advantages in cost savings and consumption reducing. The radial
