This paper deals with the design of a Dual Halbach-array Tubular Linear Motor for long stroke and large force. The proposed magnetic poles arrangement is able to increase the magnetic flux density in the machine to generate large axial force. Furthermore, compared to a standard tubular linear motor, the yoke of the stator is no longer necessary. In this way, the stator is a set of teeth magnetically separated, which significantly simplifies the manufacturing of the machine. Semi-analytical model and detailed 3D finite element analysis are carried out to evaluate the performance of the proposed structure for tubular linear motor.

Abstract
This paper deals with the design of a Dual Halbach-array Tubular Linear Motor for long stroke and large force. The proposed magnetic poles arrangement is able to increase the magnetic flux density in the machine to generate large axial force. Furthermore, compared to a standard tubular linear motor, the yoke of the stator is no longer necessary. In this way, the stator is a set of teeth magnetically separated, which significantly simplifies the manufacturing of the machine. Semi-analytical model and detailed 3D finite element analysis are carried out to evaluate the performance of the proposed structure for tubular linear motor.File in questo prodotto:
