Control System Design for 16/6/8 Double‐Stator Bearingless Switched Reluctance Motor
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The 16/6/8 double‐stator bearingless switched reluctance motor (DSBSRM) is used as the object of study in this paper. To solve the problem of torque and levitation force ripples in this motor, a control system direct force control (DFC) and direct instantaneous torque control (DITC) based on the torque sharing function (TSF) are proposed.

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.

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 ...

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

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.

Control and Analysis of a Hybrid-Rotor Bearingless Switched Reluctance Motor with One-Phase Full-Period Suspension [PDF]
In the traditional control scheme of a 12/8-pole bearingless switched reluctance motor (BSRM), radial force and torque are usually controlled as a compromise due to the conflict between their effective output areas.
