Contactless Single-Phase Synchronous Generator

摘要

The invention involves a contactless single-phase synchronous generator with a quadripole loaded stator which has two cores for concentrated coils of the armature winding, two permanent magnets, two magnetic shunts, and adjustable excitation winding which includes magnets and magnetic shunts and with a windingless rotor which switches over the magnetic flux in the stator with change of its direction in the cores of the armature winding; and which is distinguished by the fact that for the purpose of simplifying the design and the technology of the production as well as improvement in the mechanical stability of the stator and the characteristics of the machine, the sheets of the stator are produced by one stamping for the forming of the magnetic conductor without joint clearances. For the purpose of widening the limits of adjustment of the output voltage on each steel sheet of the stator, there are two magnetic shunts for each bar of the permanent magnet which form a covered recess into which there is placed the respective magnet.
