According to this invention, the micromotor is used on
smaller electrical drives that exclude the influence of the
exterior electromagnetic fields. The realisation of the
micromotor is based on the use of the ceramics electrets
Description and it begins with a very simple model similar to the „step
by step” electromagnetical motors.
The invention has a remarkable didactical aspect and it is
used in “Special Electrical Machines” subject and for the
study of the operating principle of the rolling rotor
electrostatic micromotor.
