Thermal Contact Conductivity Prediction with Grey Box Model and Experimental Validation for an Axial Flux Motor
Zhaozong Li,Cheng Zhang,Fengyu Zhang,Zeyuan Xu,David Gerada,Chris Gerada,Xueping Li,Shu Zhang,Yue Zhao +8 more
TL;DR: In this article , a Grey Box frame is introduced with the testing rig to train the critical parameters that will be used in thermal model, and the thermal conductivity and heat capacity of mixture materials in the area of the segmented armature contact surface are obtained.
Proceedings ArticleDOI
Comparative Analysis of Synchronous Reluctance Machine against Conventional Induction Machine for Railway Traction
Liya Tom,M. Raza Khowja,Ramkumar Ramanathan,Gaurang Vakil,Chris Gerada,Param Anpalahan,K. Wejrzanowski,W. L. Brown +7 more
TL;DR: In this paper , the authors compared SynREL and IM for the same electrical (1.5 kV and 170 A) and mechanical specifications, and found that SynREL has a higher torque capability than IM, and around 67% of the torque at both rated and maximum speed of operation is achieved by SynREL.
Proceedings ArticleDOI
Thermo-Mechanical Modelling of Bearing Chambers of a High-Speed Starter/Generator
Antonino La Rocca,Peter H. Connor,Zeyuan Xu,Carol Eastwick,Stephen J. Pickering,Chris Gerada +5 more
TL;DR: In this article, a thermal-mechanical analysis of the bearing chambers of a high-speed electrical starter/generator is presented, which includes the estimation of the friction losses, overall thermal properties, bearing contact resistances and heat transfer coefficients.
Proceedings ArticleDOI
Comparison of V-shaped IPM Machines Winding Topologies for Heavy-duty EV Applications
TL;DR: In this paper , the authors provide a detailed review to assess both widely used and novel winding characteristics in heavy-duty electric vehicles (HDEV) to enable transportation electrification, where there is a significant performance gap between the traditional internal combustion engines and electrical machine technology.
Proceedings ArticleDOI
Axial eccentric SynRel and SPM motors analytical models validation using 3D finite element
TL;DR: In this article, the uniform and non-uniform axial eccentricity analyses of the surface mounted permanent magnet and synchronous reluctance machines were carried out using an analytical model for each considered machine.
