4, technical characteristics
4.1 The structural design is realistic, risk-free and dependable, and the potential to phase out of stage is robust.
four.2 The major insulation composition utilizing new insulating resources has substantial voltage resistance and extended motor daily life.
four.3 The temperature increase margin is large. The motor adopts F-course insulation, and the temperature increase is assessed according to the temperature rise restrict of the B pole insulation.
four.four The defense unit is superior and total.
4.one.one The stator windings and bearings are geared up with temperature detection gadgets, which can detect, alarm and vacation.
four.four.two Shutdown place heater with anti-condensation effect.
4.five Large inertia. Motors with distinct moments of inertia can be produced in accordance to person wants.
5, framework sort
5.one The total composition of this collection of motors is welded with metal plates for the frame, stop cover, and bottom plate. The motor is an impartial cavity, and the slip ring can be developed with diverse defense ranges according to consumer specifications.
five.2 Stator: The stator body is welded by steel plate. The motor stator outlet is led out by a substantial-voltage rubber cable. The outlet place can be led out from the lower element of the base or from the primary junction box on the facet of the motor.
The stator core is superimposed by reduced-reduction silicon metal sheets, and the main 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 quality to assist lengthen the provider lifestyle. It adopts VPI overall dipping paint treatment, which has high electrical overall performance, mechanical toughness, insulation overall performance, dampness resistance and thermal security.
5.three The rotor magnetic pole core is created of laminated metal plates, and has diverse structures these kinds of as magnetic pole screws and T tails. The rotor bracket has ventilation holes and is equipped with a fan, which can effectively management the temperature increase of the rotor.
5.4 Adopt seat type spherical sliding bearing. The bearings are insulated to stop shaft currents.
Use new lubricating oil and skinny-walled bearing alloy tiles, and established electromagnetic centerline symptoms.
five.5 In accordance to consumer wants, the slip ring can be developed as a good stress ventilation composition to enhance the basic safety of the motor. The total duration of the motor with the optimistic pressure ventilation structure of the slip ring is a bit improved.
six. Problems of Use
