    abstract

    We have achieved success in the development of perfect gyroscopes. They are powered by different systems, one of which is electrical power supply still used today. Earlier there existed d.c. electrical miniature motors the rotor of which was the same as that used in the gyroscope. The disadvantage of d.c. motors lies in its commutator and the difficulties in eliminating sparking, maintainning the brushes etc. These inefficiencies are solved by the use of asynchronous power supply which has beside great advantages one basic disadvantage i.e. totor slip, concerning the stator’s rotating field, which is proportional to the load current. This “error” must be eliminated. The next step in the gyroscope construction is the synchronous power supply, providing revolution independent of the mechanical and electrical load changes. However, the conventional construction of the synchronous machine for such working conditions is not convenient because of the necessary d.c. exciting power supply.
