4, specialized qualities
4.1 The structural style is realistic, protected and reputable, and the ability to step out of step is sturdy.
four.two The major insulation construction making use of new insulating supplies has higher voltage resistance and extended motor lifestyle.
4.3 The temperature increase margin is large. The motor adopts F-class insulation, and the temperature increase is assessed according to the temperature rise restrict of the B pole insulation.
four.4 The safety device is superior and comprehensive.
four.1.one The stator windings and bearings are outfitted with temperature detection products, which can detect, alarm and excursion.
four.4.2 Shutdown room heater with anti-condensation result.
four.5 Large inertia. Motors with different moments of inertia can be made in accordance to consumer requirements.
Five, framework sort
five.1 The general composition of this series of motors is welded with metal plates for the body, stop cover, and base plate. The motor is an independent cavity, and the slip ring can be designed with different safety stages according to user needs.
5.2 Stator: The stator frame is welded by steel plate. The motor stator outlet is led out by a high-voltage rubber cable. The outlet position can be led out from the reduce component of the foundation or from the principal junction box on the aspect of the motor.
The stator core is superimposed by minimal-loss silicon steel sheets, and the core sections are separated by radial ventilation ducts.
The stator winding is F grade insulation, and the temperature increase is assessed according to B quality to support lengthen the service life. It adopts VPI all round dipping paint remedy, which has substantial electrical efficiency, mechanical power, insulation performance, moisture resistance and thermal security.
five.three The rotor magnetic pole main is manufactured of laminated steel plates, and has various constructions this kind of as magnetic pole screws and T tails. The rotor bracket has air flow holes and is outfitted with a enthusiast, which can nicely control the temperature rise of the rotor.
5.4 Undertake seat type spherical sliding bearing. The bearings are insulated to prevent shaft currents.
Use new lubricating oil and slender-walled bearing alloy tiles, and established electromagnetic centerline indicators.
5.5 According to user needs, the slip ring can be developed as a good stress ventilation structure to boost the basic safety of the motor. The total size of the motor with the good pressure ventilation structure of the slip ring is somewhat improved.
