A new type of permanent magnet linear motor with reverse transverse magnetic field is proposed,which has a more compact structure.And the main electromagnetic performance of the motor has been im-proved.Firstly,the basic structure and operating principle of the motor are described,and secondly,its di-mensions are deduced.Then,maxwell finite element software is used to analyze its electromagnetic perform-ance and compare it with the traditional transversal magnetic linear motor of the same size,finding that the amplitude of its no-load back potential is increased from 2.8V to 8.5V,the no-load flux amplitude is in-creased from 0.01 Wb to 0.028Wb,while the Thrust increased from 64N to 90N.The electromagnetic thrust is derived by analytical method.Finally,a prototype is developed,and the back potential and thrust current curves of the prototype are measured.The theoretical analysis is consistent with the experimental re-sults,which verifies the rationality of the proposed new type of permanent magnet linear motor with reverse transverse magnetic field.
