4, specialized traits
four.1 The structural design is sensible, protected and reliable, and the capability to action out of stage is robust.
four.two The major insulation construction making use of new insulating resources has substantial voltage resistance and long motor life.
four.three The temperature rise margin is large. The motor adopts F-class insulation, and the temperature rise is assessed according to the temperature rise restrict of the B pole insulation.
four.four The protection system is superior and full.
four.one.one The stator windings and bearings are equipped with temperature detection devices, which can detect, alarm and vacation.
4.4.two Shutdown place heater with anti-condensation impact.
four.5 Large inertia. Motors with different times of inertia can be created according to user demands.
Five, composition kind
5.one The general structure of this series of motors is welded with metal plates for the body, conclude protect, and base plate. The motor is an unbiased cavity, and the slip ring can be made with various safety amounts according to person specifications.
five.two Stator: The stator frame is welded by metal plate. The motor stator outlet is led out by a higher-voltage rubber cable. The outlet place can be led out from the decrease part of the foundation or from the primary junction box on the side of the motor.
The stator main is superimposed by minimal-reduction silicon metal sheets, and the core sections are separated by radial air flow ducts.
The stator winding is F grade insulation, and the temperature rise is assessed in accordance to B grade to help prolong the provider life. It adopts VPI all round dipping paint treatment method, which has higher electrical functionality, mechanical energy, insulation efficiency, moisture resistance and thermal stability.
5.three The rotor magnetic pole main is made of laminated steel plates, and has distinct structures this kind of as magnetic pole screws and T tails. The rotor bracket has air flow holes and is outfitted with a fan, which can properly management the temperature increase of the rotor.
five.4 Adopt seat type spherical sliding bearing. The bearings are insulated to avert shaft currents.
Use new lubricating oil and skinny-walled bearing alloy tiles, and established electromagnetic centerline indications.
five.5 According to consumer demands, the slip ring can be made as a good stress ventilation framework to increase the basic safety of the motor. The whole length of the motor with the optimistic pressure ventilation structure of the slip ring is somewhat improved.
6. Situations of Use
six.one Voltage fluctuation: ±5% (It can run underneath ±10% under the situations of 7.3 in GB755)
six.two Frequency fluctuation: ±2%
6.three The altitude does not exceed 1000m
six.four The highest ambient temperature does not exceed +40ºC, and the least is 0ºC.
