Magnetic Field Equivalent Current Analysis-Based Radial Force Control for Bearingless Permanent Magnet Synchronous Motors
Bearingless permanent magnet synchronous motors (BPMSMs), with all advantages of permanent magnet motors (PMSMs) and magnetic bearings, have become an important research direction in the bearingless motor field. To realize a stable suspension for the BPMSM, accurate decoupling control between the electromagnetic torque and radial suspension force is indispensable. In this paper, a concise and r...

15 صفحه اولComparison between Axial and Radial Flux Pm Coreless Machines for Flywheel Energy Storage
The need of a deeper understanding of coreless machines arises with new magnetic materials with higher remanent magnetization and the spread of high speed motors and generators. High energy density magnets allow complete ironless stator motor/generators configurations which are suitable for high speed machines and specifically in flywheel energy storage. Axial-flux and radial-flux machines are ...
متن کاملDesign and Analysis of Novel Bearingless Permanent Magnet Synchronous Motor for Flywheel Energy Storage System
To effectively simplify system structure and improve power density and efficiency, a design for a motor/generator suitable for flywheel energy storage system (FESS) is proposed. The machine is an outer-rotor and coreless-stator-type bearingless permanent magnet synchronous motor (BPMSM) with a Halbach array. Firstly, the operation principle of the outer-rotor BPMSM is described. Then, the struc...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
