1. Overview
Y, YKS, YKK collection medium and large substantial voltage cage 3-period asynchronous motors have twelve cEPTr heights from H355 to H1250. The business adopts superior EPT at house and abroad, by means of a experienced and reliable design and style and manufacturing system, and brings together EPT’s a lot of several years of medium and large high voltage The new collection of products deveXiHu (West Lake) Dis.Hu (West Lake) Dis.ed by the encounter of AC motor manufacturing have the rewards of substantial performance, lower sound, minimal vibration, high reliability and convenient set up and routine maintenance.
The EPT quality and installation proportions of this series of motors comply with my country’s stXiHu (West Lake) Dis.Hu (West Lake) Dis.rds and the Worldwide Electrotechnical Commission’s IEC stXiHu (West Lake) Dis.Hu (West Lake) Dis.rds, and can be utilized as a full set of export products and a substitute for EPTed merchandise.
This collection of motors can be used to travel various EPT EPTry this sort of as enthusiasts, pumps, compressors and other mechanical equipment, and are widely used in electric EPT, EPTry, mining, metallurgy, petrochemical and other EPT and mining EPTrprises.

4, technological attributes and structure variety
4.1 This collection of motors adopts a box framework, the frame is welded from metal plates into a box condition, ligEPT excess weight, and very good rigidity. A protecting leading include or cooler is installed on the prime of the motor to faXiHu (West Lake) Dis.Hu (West Lake) Dis.tate the warmth dissipation, installation and routine maintenance of the motor.
4.two The stator adopts an external push-in shape framework, and the stator and rotor are punched from minimal-reduction non-oriEPTd cold-rolled silicon metal sheets. The stator winding is made of F-course insulation material, which has powerful insulation stand up to voltage and anti-corona capability. The winding finishes are reliably set and tied, and are dealt with with EPT stress impregnation solvent-cost-free paint (VPI) procedure, so the motor insulation functionality Exceptional and reputable, substantial mechanical power, sturdy humidity resistance and EPT services lifestyle.
4.3 The rotor cage bar can be produced of cast aluminum or copper according to efficiency parameters or consumer specifications. Among them, the solid aluminum cage bar and the conclude ring are integrally cast by centrifugal to make sure the mechanical energy and avoid the cage bar from breaking throughout the motor operation the copper bar rotor is manufactured of substantial-high quality copper material, and the cage bar is welded with the end ring by intermediate frequency welding. The welding top quality is good. Higher toughness, and via the fastening process in the groove, tremendously reduce the phenomenon of damaged copper bars.
4.four The bearing adopts two forms of rolling bearing and sliding bearing. It is determined by the EPT and pace of the motor. Its security degree is IP44, IP54 or IP55. The rolling bearing is geared up with a non-end oil injection and drainage unit, which is straightforward for consumers to use and maintain.
4.5 The primary junction box is put on the rigEPT aspect of the motor (considered from the extension end of the main shaft), or it can be positioned on the remaining aspect in accordance to consumer specifications. Individual ground terminals are presented inside and outdoors the junction box.
4.6 According to user demands, temperature measurement devices can be added to EPTant components this kind of as stator windings and bearings to faXiHu (West Lake) Dis.Hu (West Lake) Dis.tate on-website observation and distant monitoring to make sure protected and reputable procedure of the motor.
