Abstract. This study is focused on understanding the effects of key process parameters onset recrystallisation coarse, elongated, and dendritic grains as-cast microstructure during ingot-to-billet conversion, consisting successive cogging, upsetting, reheating operations, in type 316 austenitic stainless steel. The microstructural characteristics initial ingot (e.g., size, orientation morpholog...

The aim of the paper is FEM analysis of single coil BLDC motor operated as drive of small piston pump. The paper contains analysis of design, distribution of magnetic field, forces and torque under static and dynamic conditions. Voltages, currents, signals waveforms are also given as the results of analysis. The cogging torque and total torque are discussed in the paper.

A variable reluctance machine (VRM) has been proven to be an outstanding candidate for electric vehicle (EV) applications. This paper introduces a new double-stator, 12/14/12-pole three-phase hybrid-excited modular variable reluctance machine (MVRM) for EV applications. In order to demonstrate the superiorities of the proposed structure, the static torque characteristics and dynamic performance...

This paper describes the development of a permanent magnet generator for small scale wind turbines. The generator has been designed for ease of manufacture so that it can be made by small mechanical engineering companies with limited electrical engineering knowledge. The generator has also been designed to have no cogging torque so that it can be used with all horizontal and vertical axis turbi...

This paper deals with electromagnetic design and 2-D (twodimensional) magnetic field analysis of novel low force ripple linear switched reluctance (LSR) motor. The configuration that has been presented here has a higher number of rotor poles than stator poles, and the purpose of this configuration is to improve the force ripple, which is the weak point of LSRMs. In order to illustrate the confo...

The Fermilab Booster operates at a Radio Frequency (RF) harmonic number of 84 with beam in all buckets. One or two bunches of beam are systematically lost in the 8 GeV extraction process as beam is swept across a magnetic septum during the extraction kicker rise time. The prompt radiation and component activation resulting from this localized high energy beam loss become serious concerns as Boo...

The developed subdomain model accounting for tooth-tips can accurately predict the open-circuit, armature reaction and on-load field distributions in surface-mounted permanent magnet machines. Based on this field model, their electromagnetic performance of the machine, such as the cogging torque, back-EMF and electromagnetic torque, and winding inductances are calculated. The model can also be ...
