JF208 series brushless excited synchronous main generator is developed by removing slip ring and brush system and increasing AC exciter and rotating rectifier assembly based on TQFR-3000B, TQFR-3000C and TQFR-3000E synchronous traction motor. Without the electricity conducting process caused by sliding contact in the whole mechanical and electric energy conversion process by removing slip ring and brush,it succeeds in avoiding reduced or even inefficient insulation for the motor caused by carbon powder so as to reduce maintenance and enhance the reliability of main generator. JF208A1 is exported to such country as Iran and Saudi Arabia.
Technical Feature
1. Motor structure: being three-phase brushless excited salient pole synchronous generator with horizontal single bearing structure, E32626QTY single-row cylindrical roller bearing is installed at shaft extension end with shat extension 1:10 taper to help transmission and the other end is connected to diesel engine by flexible coupling.
2. Ventilation: it adopts protection radial self- ventilation with cooling air entering from end cover air inlet,blown by scoop-type fan installed at the two ends of rotor, blown by scoop-type fan installed at two ends of the rotor and discharged from air outlets above and below the frame.
3. Excitation: brushless excitation
