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

Motor-generator group consists of a free piston Stirling<br />
engine fitted with the linear extension of an electric<br />
generator. The work produced by the Stirling engine is<br />
Description transmitted to the linear electric generator which has an<br />
inductor consists of a rod made of brass that is placed in<br />
opposition, several ring-shaped permanent magnets. The<br />
movement of the magnets inside the coil generates<br />
electricity.<br />
