A high-speed squirrel-cage induction machine requires a totally different design compared to the traditional squirrel cage industrial motor because of the mechanical limitations caused by the high speed. This results in a more complicated rotor construction and expensive material selection, and sets higher standards for the manufacturing precision. The objective of this paper is to demonstrate the design aspects, material selection, and manufacturing of a squirrel cage rotor for high-speed applications. In this paper, the rotor dimensioning approach based on equations and data analysis is presented. Rotor material selection and construction topology influence on the electrical machine design are discussed. The results are illustrated with the design of a 6 kW, 120 000 rpm induction machine for a turbo-circulator. The rotor parameters' influence on the electromagnetic performance of the designed machine is demonstrated. Mechanical stresses for different topologies are studied with Finite Element Method (FEM) analysis. Several manufacturing methods for producing a high precision rotor are described and compared. The presented rotor design approach, which enables high electromagnetic performance and robust construction, is verified by the testing of a prototype.

“…Potential challenges of the SMC material are cost and availability. The mechanical challenges of Vacoflux are the tensile strength (resistance of a material to breaking under tension) and creep limit (magnitude of the maximum allowable stress), [11] which is nearly 30-32 and 30-35% lesser than silicon steels, respectively.…”

Line-start synchronous machines (LSSMs) emerged as an efficient alternative for induction machines in numerous constant speed applications. This study reviewed evolution, technological advancements, design concepts, optimisation techniques, and possible applications in a comprehensive manner. A case study on the reviewed LSSM has been carried out based on its suitability in agricultural applications in India. Further, the performance comparison and significant advantages between the existing induction machine and LSSM are finally discussed.

“…A new descent direction is obtained by searching the minimum of (3) on the free variable subspace, by using the following formulation: (8) In this step, the feasibility domain is reduced at a subspace of the feasibility domain , by considering as free variables, the variables that are not fixed on limits during the Cauchy point step: (9) The others variables are fixed on their boundary value obtained during the Cauchy point step. (10) TheThir dStep-LineSear ch: It achieves a linear search on to find a new point that satisfies a sufficient decrease condition and a curvature condition (known also as Wolfe's conditions). The line search implies successive one-dimensional interpolations (quadratic or cubic) to compute an acceptable step from point to point.…”

“…6(a)) is carried out in order to obtain a maximum flux density variation in the regenerator air gap, to ensure the performance of the magneto caloric device. To limit the saturation, the extremity of the rotor pole is realized on a cobalt-iron alloy "Vacoflux" with a high saturation flux density [10]. An initial optimal design has been obtained with using only two parameters.…”

This paper investigates the capability of a Quasi-Newton optimization algorithm, the L-BFGS-B one, to reduce the drawbacks of the direct coupling with FEM models. After a short description of the L-BFGS-B algorithm, the authors have tested it to the TEAM Workshop Problem 25. L-BFGS-B algorithm issues linked to FEM estimation of the objective function have been analyzed. Finally the authors present the results of an electromagnetic device optimal design, using a large number of parameters (47).
