Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...

This paper presents an analysis by which the dynamic performances of a permanent magnet synchronous motor (PMSM) motor is controlled through a hysteresis current loop and an outer speed loop with different controllers. The dynamics of the wind turbine pumping drive system with (PI) and a fuzzy sliding mode (FSM) speed controllers are presented. In order to optimize the overall system efficiency...

in this paper, the optimal design of a three phase surface mounted permanent magnet synchronous motor has been done by particle swarm optimization and bees algorithm. this machine has been designed for high speed applications, and an epoxy and glass fiber bandage is used for permanent magnet protection against centrifugal forces. the optimization has been done by new design equations to improve...

Due to the lack of mature design program for the tubular permanent magnet linear wave generator (TPMLWG) and poor sinusoidal characteristics of the air gap flux density for the traditional surface-mounted TPMLWG, a design method and a new secondary structure of TPMLWG are proposed. An equivalent mathematical model of TPMLWG is established to adopt the transformation relationship between the lin...

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 ...

Abstract The article introduces the results of studying magnetic field distribution in alternator inductor with an axial arrangement open cores (OMC) and external closure fluxes. study compares efficiency using fluxes from permanent magnets (PM) on example two model variants inductors OMC developed by authors. analysis density was carried out 3D modelling EMWorks software. It has been shown tha...

The paper deals with analysis of dynamic behavior of a feedback flux weakening control of PMSM traction drive for light vehicles. The PMSM flux weakening is very important for traction drives. Two torque control structures were analyzed pure feedback control and feedback control with prediction of the field producing current component. The principles, control structures, simulation and experime...
