4, complex qualities
4.one The structural layout is affordable, secure and dependable, and the capability to stage out of phase is sturdy.
4.2 The primary insulation composition employing new insulating components has high voltage resistance and long motor daily life.
four.three The temperature increase margin is large. The motor adopts F-course insulation, and the temperature rise is assessed according to the temperature rise restrict of the B pole insulation.
four.4 The safety unit is superior and full.
4.1.1 The stator windings and bearings are equipped with temperature detection gadgets, which can detect, alarm and journey.
4.4.2 Shutdown place heater with anti-condensation effect.
four.5 Big inertia. Motors with distinct times of inertia can be made in accordance to user demands.
5, framework variety
five.one The overall construction of this series of motors is welded with steel plates for the frame, stop include, and base plate. The motor is an unbiased cavity, and the slip ring can be made with diverse defense amounts according to person needs.
5.2 Stator: The stator frame is welded by steel plate. The motor stator outlet is led out by a higher-voltage rubber cable. The outlet position can be led out from the reduce element of the base or from the major junction box on the facet of the motor.
The stator core is superimposed by low-decline silicon metal sheets, and the main sections are divided by radial air flow ducts.
The stator winding is F grade insulation, and the temperature increase is assessed according to B grade to aid increase the support life. It adopts VPI total dipping paint treatment method, which has higher electrical functionality, mechanical energy, insulation efficiency, dampness resistance and thermal security.
5.three The rotor magnetic pole main is produced of laminated metal plates, and has diverse buildings such as magnetic pole screws and T tails. The rotor bracket has air flow holes and is geared up with a enthusiast, which can nicely control the temperature increase of the rotor.
5.4 Adopt seat kind spherical sliding bearing. The bearings are insulated to prevent shaft currents.
Use new lubricating oil and thin-walled bearing alloy tiles, and set electromagnetic centerline symptoms.
five.five According to consumer wants, the slip ring can be designed as a good strain ventilation composition to boost the security of the motor. The whole size of the motor with the constructive strain ventilation framework of the slip ring is a bit increased.
6. Conditions of Use
