FIELD: electromechanical engineering; transducers of automatic-control devices and systems. SUBSTANCE: induction generator that has field winding and generator winding is provided, in addition, with two relatively perpendicular compensating windings forming short-circuited loop enabling stabilization of magnetic flux when rotor speed varies. This ensures lineal dependence between output signal and rotor speed. Proposed tachogenerator is most useful for automatic-control systems of industrial installations where low cost and high precision are required from separate components of automatic-control system. EFFECT: reduced speed amplitude error without appreciably impairing mass and size characteristics and use of additional hardware. |
