Four, technological attributes
four.1 The structural design is reasonable, protected and reliable, and the capability to stage out of stage is sturdy.
4.2 The main insulation framework utilizing new insulating materials has higher voltage resistance and prolonged motor daily life.
four.three The temperature increase margin is huge. The motor adopts F-course insulation, and the temperature increase is assessed according to the temperature rise restrict of the B pole insulation.
four.4 The safety system is superior and comprehensive.
four.1.1 The stator windings and bearings are outfitted with temperature detection devices, which can detect, alarm and excursion.
4.four.two Shutdown place heater with anti-condensation impact.
four.five Big inertia. Motors with different times of inertia can be produced according to person needs.
5, composition kind
five.1 The general composition of this sequence of motors is welded with steel plates for the frame, end cover, and bottom plate. The motor is an unbiased cavity, and the slip ring can be developed with different security amounts according to consumer demands.
5.2 Stator: The stator body is welded by metal plate. The motor stator outlet is led out by a large-voltage rubber cable. The outlet placement can be led out from the lower portion of the base or from the primary junction box on the facet of the motor.
The stator main is superimposed by reduced-decline silicon steel sheets, and the core sections are divided by radial air flow ducts.
The stator winding is F quality insulation, and the temperature increase is assessed in accordance to B grade to assist increase the provider life. It adopts VPI total dipping paint therapy, which has higher electrical overall performance, mechanical toughness, insulation efficiency, humidity resistance and thermal balance.
5.three The rotor magnetic pole core is made of laminated metal plates, and has diverse buildings this sort of as magnetic pole screws and T tails. The rotor bracket has ventilation holes and is geared up with a fan, which can properly control the temperature increase of the rotor.
five.four Undertake seat type spherical sliding bearing. The bearings are insulated to avert shaft currents.
Use new lubricating oil and thin-walled bearing alloy tiles, and set electromagnetic centerline indicators.
five.5 According to user demands, the slip ring can be created as a good stress ventilation framework to boost the protection of the motor. The total length of the motor with the constructive force ventilation framework of the slip ring is marginally elevated.
six. Situations of Use
