This paper deals with peculiar design of high frequency 15 kW synchronous permanent magnet motor having raised technical and economic parameters. Reduction of losses is achieved by slotless stator core structure. Performance motor characteristics are increased by special rotor design: the rotor has two parts which are moving under inner stator diameter and over outer stator diameter, so the both sides...
This paper deals with the design of the high speed turbogenerator of 6000 kW rating at 12000 rpm for local power engineering having raised technical and economic parameters. Some questions of the optimal construction with mechanical and electromagnetic characteristics are estimated. For principal decision of mechanical problems for turbogenerator it's necessary to use new materials of higher strength...
This paper deals with the FEA study of permanent magnet synchronous and two-ply rotor induction motor 3150 kW, 500 rpm and analysis of line-starting behavior, calculation of its parameters and performances are represented. The synchronous PM motor can reach the speed of rotation close to synchronous one if the asynchronous electromagnetic torque will be greater than the braking electromagnetic torque...
