Abstract


A system which contains two or more multilayer solenoid coils is a kernel of step motors. There is a "strong" permanent magnet inside the solenoid coils. The magnet is being moved by the action of electromagnetic field force, which is caused by the coils. Numerical calculations combined with analytical expressions for electromagnetic field strength that exists in the core of step motors, magnetic flux and force on moving magnet, which transforms translational motion into rotational motion, are given in this paper. By comparing with an experimental result, it will be shown that the proposed technique is accurate and effective in calculating both electromagnetic field distribution and strike force of permanent magnet.
