Coreless Linear Induction Motor (LIM) for Space-borne Electro-magnetic Mass Driver Applications

Completed Technology Project

Project Introduction

Large scale linear induction motors use ferromagnetic cores, but at high speed these cores choke the system’s ability to transform electrical energy into mechanical energy. Use of composite materials can be used to replace structural support previously provided by ferromagnetic materials. However, coreless motors lack the structural support usually provided by the iron core in a traditional LIM. Designing a rigid coreless LIM will require material studies and detailed thermal/structural analysis.
