Abstract
This paper considers the design and analysis of a tubular linear permanent magnet machine for high force density applications, such as in the aerospace industry. Different machine topologies and slot-pole combinations are considered. Optimization with respect to machine geometry is addressed analytically and validated through finite element simulations. A technique to reduce heat build-up in the winding coils is introduced, allowing for higher current density and subsequently resulting in a higher output force for a given winding temperature rise.Keywords
