Considerations for Manufacturing and Experimental Validation of a PM, Tubular Motor for a Matrix Converter Driven Aerospace Application

This paper deals with the manufacturing and the experimental verification of a tubular, linear, permanent magnet (TLPM) motor. A brief re-cap regarding the design and optimization procedures of a high force density, TLPM motor, presented in previous papers is first given. The design includes a novel, thermal management technique that is implemented in order to improve the thermal performance and thus improve the force density performance of the machine. Manufacturing and assembly of tubular motors is traditionally difficult and costly, thus details of the manufacturing and assembly procedures adopted are presented. The TLPM motor is finally assembled on a dedicated aerospace drive rig fed through a matrix converter. Experimental validation is achieved and compared to the modeling results.
