1.Single winding generator can be used directly 2.Single winding generator low cost 3.Single winding generatorsimple structure

Product Features:1) In principle, the single-winding inner electronic regulator uses current inner loop, voltage outer loop negative-paralell and no loop current speed regulation control theory, the circuit advanced, practical, with simple structure and reliable operation. 2) From the structure, the excavator single-winding electronic regulator system replaced magnetic amplifier system for single-winding excitation, control cabinet structure is more simple, quantity of elements reduced, for the single-winding excitation windings ,without technical transformation ,it can be used directly, so that the cost of electrical transformation of equipment significantly reduced.
