Analysis of high speed induction motor for spindle made by copper die casting process

Abstract

This paper deals with the analysis techniques of a high speed and high efficiency 10 kW, 30,000 rpm rated induction motor. The induction motor has been analyzed by time-varying magnetic finite element method and the test results show that there is a possibility that the motor could be used in a high speed spindle system application. All performances of the prototype are successfully verified. All analysis techniques are introduced to develop a high speed and high efficiency induction motor of copper die casting. The analysis techniques are composed of an electrical technique (magnetic analysis), and a mechanical technique (casting analysis, structural analysis, critical speed analysis and unbalance response analysis). Simulation results are compared with the experiment, and are within a 3% deviation.
