Considerations on the Optimal Computer-Aided Design of Induction Motors from the Turbomachines Drive Systems in Power Plants

Abstract

In this paper, the authors present the optimal computer-aided design of a high-speed three-phase induction motor with a torque-speed curve suitable for the turbomachines drive systems in power plants. The design of this motor was approached classically, previously by the conventional calculation method.In order for this method to be verified, first the modern design of the induction motor, using RMxprt and then techniques for optimizing its design, is analyzed.The paper describes how a parametric analysis can be setup to design and model the performance of rotating electric machines. This parametric analysis specifies all of the design variations based on the variable geometry of the stator and rotor slots that optimetrics drives Maxwell to solve. Also Maxwell 2D Design software is used as finite element analysis tool in order to design and model the performance of this induction motor having 225 kW, 2 poles, 2976 rpm.
