Linear electric motors designed on the basis of permanent magnets have disadvantage. It is caused by nonlinear distribution of a magnetic flux density around the cylindrical permanent magnet. Therefore, the motors should be designed with the high level reserve power. It lids to increase of mass - dimensional parameters of a motor. In addition, it complicates a control system of an electric drive on base of the linear motor. These disadvantages are eliminated by using, offered by authors, of three-zoned permanent magnetic structures. Using the three zone magnetic structures on basis Nd-Fe-B permanent magnets allows reducing weight - dimensional parameters of the linear motor. In this paper is considered design technique of creation the tree zone magnet structure. As an example, it was designed linear electrical motor (actuator) for diesel speed electronic controller. Prototype electronic speed controller was build and tested.
