To solve the problem of reduction of suspension force of permanent magnet system with variable magnetic flux path control, according to the structure of the system, suspension principle of the permanent magnet system with variable magnetic flux path control and the generation principle of the load torque, the influence of the mechanical structure of the system on the suspension force is analyzed by changing part of parameters of the system structure. The results show that the existence of magnetic isolation plate is the main reason for the decrease of suspension force, the permanent magnet ring can be thickened to 11.91 mm, the annular gap can be reduced to 1 mm, thickness of the “F” shaped magnetizer can be increased to 9 mm to increase the suspension force.

A study for the enhancement of effective magnetic flux of Permanent Magnet-Transversal Flux Machines using flux guiding is presented. By taking into account an intrinsic demagnetization curve which considers the leakage flux, the stator winding can be more compact; furthermore, a lighter stator and a more efficient permanent magnet machine can be obtained by using magnetic flux path guiding.

This paper proposes a noncontact magnetic suspension of an iron ball using a flux path control mechanism. In this system, the suspension force is generated by a disk-type permanent magnet, and controlled by varying the angle of the permanent magnet that is driven by a rotary actuator. In this paper, first, the suspension principle is explained, and the prototype is introduced. Second, the characteristics of this system are examined by some basic experimental results. Third, a model is created, and the numerical simulation is carried out. Finally, the suspension experiments are succeeded using the prototype, and the results are shown and discussed.
