“…To model the thermal behavior of SRMs, lumped parameter thermal networks (LPTNs) [57] or computational fluid dynamics (CFDs) and FEAs [58] are used. Space-resolved lumped parameter thermal networks have been proposed to predict the hot-spot temperature as well as the temperature at any userspecified spot within the machine [59]- [62].…”

Abstract-Electrical drives are one of the major consumers of electrical energy and their penetration in the market is still growing. Hence, for many drive applications efficient, reliable and cost effective solutions have to be found. Switched reluctance drives (SRD) offer a potential solution when focus is mainly on cost and robustness. However, to benefit from the unique advantages of this machine type a deep understanding of its strongly non-linear behavior is required. After discussing some major differences to classic rotating field machines, this paper presents a broad overview of the state of the art of SRD taking into consideration all aspects relevant to machine modeling, design and control development process. Finally, applications on the market utilizing SRDs and the focus of current research is presented. After reading this paper the reader will be able to assess if this modern drive technology could be advantagous in a given application.

The effort attempts to investigate the influence of various non-oriented electrical steel sheets on the core loss of a switched reluctance motor (SRM). The core loss of the motor inherits a strong correlation with flux density and permeability of the material. The study involves the use of laminated 2.7 % high silicon steel suitable for the motor in view of its higher flux density and lower core loss. The accurate prediction of core loss leaves way to suggest measures for improving the performance of the SRM. The dynamic simulation measurements of a 1.5 kW, three-phase 12/8 SRM involve the finite element method (FEM) and use the data obtained experimentally from Epstein frame. The closeness of the simulated and hardware results obtained with laminations of M400-50A, DI MAX-M19 and DI MAX-M15 both for the stator and rotor, espouse a greater significance to the findings in terms of the core loss density and forge new dimensions for its use in the drive industry.

“…The Electric currents and friction in an electric machine generate heat. Hence temperature of different parts of the machine rise which could cause deterioration of insulation in windings [1], thermal stress, efficiency reduction and this may lead to motor failure. Also under high loads, temperature rise influences the machine electrical and magnetic parameters [2].…”

Abstract-This paper presents the two dimensional (2-D) steady state and transient thermal analysis in Switched Reluctance machine (SRM) to observe actual heat distribution in the parts of the machine using finite element method. Electromagnetic losses which form the heat source is calculated taking into consideration both skin effect and proximity effect. A 2-D steady state analysis is carried out to observe the temperature distribution and maximum temperature for wide range of speed and load conditions. From the analysis it is found that the maximum temperature is reached in the speed range of 1500 rpm. The load corresponding to maximum temperature is taken as initial condition for the transient thermal analysis. From the transient analysis, heat distribution at various load steps and the time to reach the steady state are observed. Simulation results for a 6/4 SRM are presented under steady state and transient conditions. As a result, thermal analysis plays a great significance for the long term stability of the machine.
