【Abstract】 TPMLM is a new electrical driver,which can directly transform electric energy to linear mechanical motion,with the advantage of rapid reaction,simple structure etc,which is widely used in the field of linear drive. In order to improve thrust properties and the sine property of air-gap flux density,the pole-slot number combinations,and winding models were analyzed systematically to find the influence on TPMLMs,and determine the structure parameters finally with finite element method. The conclusions can provide some theoretical guidance for analysis and design of linear motor.更多还原
