In order to improve the performance of bearingless switched reluctance motor (BSRM), this paper proposes a new double stator motors (DSBSRM). The DSBSRM adopts an inner and outer structure, stators are separated by magnetic isolation frame solve coupling problem between torque control suspending force control. system, working mode hybrid excitation, permanent magnets used provide bias field, el...

In order to solve the problems of low integration, reliability, and high cost caused by mechanical sensors used in bearingless permanent magnet synchronous motor (BPMSM) control systems, a novel speed displacement sensorless method using least-squares support vector machine (LS-SVM) left inverse system is proposed this paper. Firstly, suspension force generation principle BPMSM introduced, math...

A bearingless brushless direct current (BLDC) motor incorporates the function of magnetic bearings into a BLDC motor, making it new type high-performance motor. In this paper, main windings are used to generate radial force cancellation by injecting required dc current, “integrated winding configuration”. The (DC) system model is established with aid (ANSYS/MAXWELL) software. simulation results...

pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...

The axial permanent magnet magnetic bearingless flywheel machine (APM-BFM) mostly operates under the state of high-power fast charging and discharging. Due to characteristics density per unit volume, centralized windings have small heat dissipation area high thermal loads, temperature rise on APM-BFM is a very important issue. Thermal analysis thus particular importance particularly for modern ...
