Abstract

Magnetic transmission is a special kind of transmission. It is mainly used in the special occasions of noncontact power and movement transmission utilizing the characteristics of the non-contact of magnetic force interaction. It can be divided into three types according to different forms of movement: rectilineal motion transmission, rotational motion transmission and complex motion transmission. This paper reviews various recent patents in all types of magnetic transmission and various applications. The patents reviewed concern a period extending from the year 2000 up to date. The applications concern mainly integrated all types of motion transmission covering the area connected with the production of pump, stirrer and other industrial mechanism using modernization that has reached by material replacing, geometry, and embedding additional units into main design. The list of patents reviewed is by no means complete or extensive it shows however the extent of the subjects covered in patents in this area during the last five years. The paper concludes with a description of the future developments expected in the subjects covered.
