YRKK Series Large size H710-1000 Documentation
This motor can be processed by the anticorrosion anti-mould-proof process to derive outdoor (W) and outdoor corrosion protection (WF) motors.
High efficiency and energy saving.
Low vibration.
Reliable performance.
Easy installation and maintenance.
The frame is made of steel plate being welded up into form of square tank shape with light weight and firm rigidity.
Stator is an outer-press-assembly structure.
The stator winding is F grade insulation at the winding’s end part being firm banded.
The whole stator and rotor has been treated with VPI technology to make stator and rotor with insulation and moisture resistance.
Silver brazing is used between rotor coils and between copper strip and coils to ensure the reliability of motor operation.
General purpose including machine tool, compressor, water pump, ventilator, conveyor, crushing mill,
