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 ...

Improved Bearingless Switched-Reluctance Motor [PDF]
, 2003 The Morrison rotor, named after its inventor, is a hybrid rotor for use in a bearingless switched-reluctance electric motor. The motor is characterized as bearingless in the sense that it does not rely on conventional mechanical bearings: instead, it ...

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

Electromagnetic Modeling and Investigation for Bearingless Switched Reluctance Motor Considering Magnetic Saturation [PDF]
, 2022 For 12/4 bearingless switched reluctance motors (BSRMs), the levitation forces are generated in the maximum-inductance flat region of each phase. The magnetic saturation can be reached with the increase in ampere turns.

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 A Bearingless Switched Reluctance Motor (BSRM) has a complicated character of nonlinear coupling; therefore, it is a hard work to operate BSRM stably. In this paper, a new type of BSRMs with novel rotor structure is proposed by analyzing relationships between motor structure and theoretical formulae of levitation force and torque.
