Self reactanceXd in direct axis ’d’ and self reactanceXq in quadrature axis ’q’ influence the load characteristics of the permanent magnet machine. Their calculation methods are known. All calculations should be verified by measurements. Measurement with AC variable voltage and frequency source applied on stator winding is correct when eddy currents do not exist. Other methods evaluate the DC c...

Isogeometric Analysis (IGA) is used to simulate a permanent magnet synchronous machine. IGA uses Non-Uniform Rational B-splines (NURBS) to parametrise the domain and to approximate the solution space, thus allowing for the exact description of the geometries even on the coarsest level of mesh refinement. Given the properties of the isogeometric basis functions, this choice guarantees a higher a...

The purpose of this paper is to present a new double-sided linear primary permanent magnet (PM) vernier (DSLPPMV) machine, which can offer high thrust force, low detent force, and improved power factor. Both PMs and windings of the proposed machine are on the short translator, while the long stator is designed as a double-sided simple iron core with salient teeth so that it is very robust to tr...

Rapid developments are occurring in design of electrical machines and its control. To get optimum performance under normal/fault condition needs implementation of fault tolerance. Next decade is of Permanent Magnet Synchronous Machines. The paper presents mathematical modeling of PMSM. A current and speed controller is designed to implement fault tolerance and its stability analysis.
