Abstract: A bidirectional crosslinking transverse flux tubular linear permanent magnet synchronous motor was presented,which had larger space utilization ratio than traditional transverse flux machine.The primary core unit can make full use of secondary permanent magnets,and effectively increase no-load back-EMF,with the features of easy manufacture.The structure and driving principleof this motor were introduced.The three-dimensional magnetic circuit model was established and the analytical expression of no-load back-EMF and the thrust were derived.In additional,the magnetic field and thrust were analysised by 3-D finite element method.A prototype was designed and manufactured.The back-EMF and static thrust experiments were carried out.The theoretical analyses fit the experiment results well.That verified the validity of the theoretical analysis.
