Siemens Beide YBF main well ventilated dedicated high-voltage flameproof motors
YBF on a whirlwind series of large machines for the main fan motor is designed for domestic power FBCDZ series of rotating main fan design supporting products, motor housing using steel plate welded structure, H500 following motor using external cooling fins Cadogan the latest international structure of the tank circulating air duct, H500 or more cooling with built-in pipe (air / air cooling) structure, the stator windings with VPI whole leaching process, either aluminum or copper rotor cage rotor are made of heat-set process, the motor has a winding test temperature element (Pt100) 6 artery (three in use, three spare), bearing temperature element (Pt100) 2 artery (before and after each one), these measures increase the reliability and life of the motor is running.

The product compared with the previous YBF series motor, has the following advantages:
1, bearings bearing composite structure with four independent intellectual property rights, the bearing structure with strong bearing capacity and impact vibration capabilities, and a good self-aligning feature, the system can eliminate interference due to deflection, caused by different heart force. The fundamental structure of the Tornado aircraft solution to the problem of short bearing life, is a large bearing on the Tornado aircraft dedicated structure.
2, bearing with thin oil lubrication, the bearing and always maintain good lubrication, cooling condition, clean state, to further improve the reliability of the bearing operation, significantly reduced motor maintenance workload.
Variable frequency motor cooling system uses forced air to ensure that the cooling air motor running at various speeds. The product is also a reliable bearing insulation treatment, and additional rotor axis current extraction device, to avoid harm to the bearing axis current.
