4, complex characteristics
4.1 The structural design and style is reasonable, risk-free and dependable, and the ability to stage out of stage is powerful.
4.2 The principal insulation composition using new insulating resources has large voltage resistance and long motor lifestyle.
four.three The temperature increase margin is massive. The motor adopts F-course insulation, and the temperature increase is assessed in accordance to the temperature rise limit of the B pole insulation.
4.four The security system is innovative and complete.
4.one.1 The stator windings and bearings are outfitted with temperature detection products, which can detect, alarm and journey.
4.4.2 Shutdown space heater with anti-condensation result.
4.five Large inertia. Motors with various times of inertia can be developed according to consumer requirements.
Five, framework variety
5.1 The overall framework of this collection of motors is welded with steel plates for the body, conclude go over, and bottom plate. The motor is an unbiased cavity, and the slip ring can be made with distinct safety amounts in accordance to person demands.
five.2 Stator: The stator body is welded by steel plate. The motor stator outlet is led out by a high-voltage rubber cable. The outlet place can be led out from the reduced component of the base or from the major junction box on the side of the motor.
The stator core is superimposed by minimal-reduction silicon metal sheets, and the core sections are divided by radial ventilation ducts.
The stator winding is F quality insulation, and the temperature rise is assessed according to B quality to support prolong the service daily life. It adopts VPI all round dipping paint treatment, which has large electrical functionality, mechanical energy, insulation performance, dampness resistance and thermal steadiness.
5.3 The rotor magnetic pole core is made of laminated steel plates, and has diverse buildings this sort of as magnetic pole screws and T tails. The rotor bracket has air flow holes and is geared up with a fan, which can nicely control the temperature rise of the rotor.
five.four Undertake seat variety spherical sliding bearing. The bearings are insulated to prevent shaft currents.
Use new lubricating oil and skinny-walled bearing alloy tiles, and set electromagnetic centerline indications.
5.five In accordance to user wants, the slip ring can be designed as a constructive stress air flow framework to increase the protection of the motor. The overall duration of the motor with the optimistic force air flow structure of the slip ring is somewhat increased.
6. Problems of Use
six.one Voltage fluctuation: ±5% (It can run below ±10% underneath the situations of 7.3 in GB755)
6.2 Frequency fluctuation: ±2%
six.3 The altitude does not exceed 1000m
six.four The greatest ambient temperature does not exceed +40ºC, and the bare minimum is 0ºC.
