The spoke type rotor can be used to obtain magnetic flux concentration in permanent magnet machines. This allows the air gap magnetic flux density to exceed the remanent flux density of the permanent magnets but gives problems with leakage fluxes in the magnetic circuit. The end leakage flux of one spoke type permanent magnet rotor design is studied through measurements and finite element simul...

Faults in electrical machines can vary in severity and affect different parts of the machine. This study focuses on various kinds of short-circuits on the terminal side of a generic 20 kW surface mounted permanent magnet synchronous generator and how successive faults affect the performance of the machine. The study was conducted with the commercially available finite element method software CO...

In this paper we present an approach to the conversion of the power generated by a seawave power generator integrated in an offshore wind power farm. The article is focused on low power generators that could be used in offshore installations. The generator is a Permanent Magnet (PM) linear generator that generates highly distorted emfs. We propose and compare two possible ways to connect the ge...

The aim of this research is to optimize the design an 18-poled 8000 rpm 7 kVA high-speed permanent magnet synchronous generator. goal find best factor levels for parameters, namely thickness (MH), offset, and embrace (EMB) responses efficiency (%), rated torque (N.m), air-gap flux density (Tesla), armature current (A/mm2), thermal load (A2/mm3). keep at 1 tesla while maximizing minimizing rest ...
