Considerations for Manufacturing and Experimental Validation of a PM, Tubular Motor for a Matrix Converter Driven Aerospace Application
TL;DR: In this paper, the manufacturing and verification of a tubular, linear, permanent magnet (TLPM) motor is described. And the TLPM motor is finally assembled on a dedicated aerospace drive rig fed through a matrix converter.
Proceedings ArticleDOI
A system level comparison of drive topologies for high speed electrical machines
TL;DR: A comprehensive comparative study among five different converter topologies all designed to drive a 8.5kW-120krpm surface permanent magnet synchronous machine aims at comparing the considered systems in terms of converter complexity, control complexity and overall efficiency.
Journal ArticleDOI
Magnetic Field and Torque Output of Packaged Hydraulic Torque Motor
TL;DR: In this article, the magnetic field distribution in the air gaps and the magnetic saturation in the iron blocks are analyzed by using a numerical approach, and the torque generation with respect to the current input and assembly errors is analyzed in detail.
Proceedings ArticleDOI
Comparison of analytical and FE modeling of Vernier Hybrid Machine
TL;DR: In this paper, a VHM is analyzed using a computationally efficient analytical methodology whose results are compared to those obtained using Finite Element (FE) method, and the results show that the VHMs are suitable for high torque density, low speed, minimum weight and compact design.
Proceedings ArticleDOI
