“…Such devices are currently used in many industries: machine tools, transport, robotics, control and protection systems, etc. Тhe introduction of this type of drive, which uses reciprocating motion, will save about 30 % of electricity [9]. For example, in the oilproducing industry, CLVD can be used for rodless oil production from wells with submersible units, which can serve as an alternative to the rocking machines that are widely used today.…”

Reduction of the pull effect of a cylindrical linear synchronous motor

A theoretical and experimental study of the effect of gravity, which occurs in a cylindrical linear synchronous motor between the secondary element and the inductor, was carried out. As a result, the forces of mechanical friction of the secondary element on the inductor are formed, which entails touching the secondary element on the surface of the inductor. An unfavourable result is a weakening of the power force that is working for a cylindrical linear synchronous motor. Two different inductor designs for a cylindrical linear synchronous motor have been studied. When solving this problem, we used an approach based on a combination of the field theory method and the theory of electric circuits. The forces of gravity, friction, and force between the secondary element and the inductor for these structures are determined. Experimentally, it was found that the pull force significantly weakens the working force of the engine. Based on the results obtained, conclusions were drawn about the need to change the design of the inductor. The design change of this element consists in the use of a non-magnetic intermediate centralizer, which is inserted between two sliding bearings located at the ends of each module of a cylindrical linear synchronous motor. Also, changes were made to the design of the magnetic circuit, in which instead of one slot for a three-phase winding system, three symmetrical slots were made, each for its own phase of the three-phase winding. As a result, the magnetic system of the engine in question became axisymmetric. The measures taken to change the design of the engine in question allowed us to dramatically reduce the effect of gravity. As a result, the specific force has increased significantly.
