Abstract
This paper presents a construction of the flat stepper motor with a complex move of soft magnetic plate with one multipolar permanent magnet. Stator has 16 cylindrical electromagnets which are combined in 4 phases. This solution is advantageous because it simplifies the way of controlling motor. In this case there are only 8 wires and the external driver controls currents in only 4 phases. Unlike in the solutions where many glued permanent magnets are used, it was considered a possibility to produce one permanent magnet which will be multipolarly magnetized. A special magnetization fixture allows hard magnetic material to be magnetized in the required distribution of poles. Flat stepper motor with multipole permanent magnet can lead to further considerations on the construction of linear rotary motor.
