4, technological attributes
four.one The structural design and style is reasonable, protected and trustworthy, and the potential to phase out of action is powerful.
4.2 The primary insulation construction utilizing new insulating materials has high voltage resistance and prolonged motor life.
four.3 The temperature increase margin is large. The motor adopts F-course insulation, and the temperature increase is assessed according to the temperature rise limit of the B pole insulation.
four.4 The protection unit is sophisticated and comprehensive.
4.one.1 The stator windings and bearings are equipped with temperature detection products, which can detect, alarm and vacation.
four.four.two Shutdown area heater with anti-condensation effect.
four.5 Massive inertia. Motors with various times of inertia can be developed according to person demands.
5, structure type
five.1 The overall framework of this series of motors is welded with steel plates for the frame, stop protect, and bottom plate. The motor is an unbiased cavity, and the slip ring can be made with different security ranges according to consumer demands.
five.2 Stator: The stator body is welded by metal plate. The motor stator outlet is led out by a higher-voltage rubber cable. The outlet placement can be led out from the decrease part of the foundation or from the main junction box on the facet of the motor.
The stator main is superimposed by lower-reduction silicon metal sheets, and the core sections are divided by radial air flow ducts.
The stator winding is F quality insulation, and the temperature rise is assessed in accordance to B quality to support increase the services daily life. It adopts VPI all round dipping paint remedy, which has higher electrical efficiency, mechanical strength, insulation overall performance, dampness resistance and thermal balance.
5.three The rotor magnetic pole core is created of laminated metal plates, and has various buildings this sort of as magnetic pole screws and T tails. The rotor bracket has air flow holes and is equipped with a admirer, which can properly control the temperature increase of the rotor.
5.four Adopt seat kind spherical sliding bearing. The bearings are insulated to stop shaft currents.
Use new lubricating oil and slim-walled bearing alloy tiles, and set electromagnetic centerline indications.
5.5 In accordance to user requirements, the slip ring can be made as a optimistic pressure ventilation framework to increase the safety of the motor. The whole size of the motor with the constructive strain ventilation framework of the slip ring is a bit improved.
6. Circumstances of Use
six.1 Voltage fluctuation: ±5% (It can run underneath ±10% underneath the problems of 7.3 in GB755)
