YKS YKK series high voltage squirrel-cage three-phase asynchronous motor new series from H355 to H1120 a total of 11 center heights, voltage grade 6KV, 10KV two kinds.
The design and development of the series of motors adopts advanced calculation and analysis technology, coupled with the use of superior raw materials and sophisticated processing technology and equipment in manufacturing, making the series of motors have the advantages of high performance index, low noise, low vibration and high reliability.
The series motor fully conforms to the national standard GB755 "Rotating motor quota and performance" GB/T10069 "rotating motor operating sound measurement method and noise limit.
GB/T10068 "Measurement, evaluation and limits of mechanical vibration of motors with shaft center height of 56mm and above" and related IEC standards. Basic reference to JB/T7594JB/T10314.1 JB/T10314.2, JB/T10445 and GB/T13957 industry standards, but the power level is extended, part of the installation size change shape.
The basic design of the series motor is a horizontal installation mode with foot (IMB3), the operation rating is continuous (S1), the rated frequency is 50Hz, and the insulation is F class. Under normal circumstances, the motor has four basic protection levels :IP23IP44, IP54 and IP55.
Series of motor cooling methods are usually :1C01IC81WIC611IC616 and IC666 a total of 5.
If the customer needs other forms of requirements (such as: installation mode, protection level, cooling mode and voltage level, etc.), you can order after signing a special technical agreement.
Motor efficiency is higher than ever.

The frame of the series motor adopts the steel plate welding structure, which makes the motor have the characteristics of good stiffness and light weight, and the optimal design of the motor structure also makes the series motor have the advantages of easy installation and maintenance.
The stator and rotor punching are made of low loss silicon steel sheet, which reduces iron consumption and improves efficiency.
The insulation class of the series motor is F class. The stator coil is a double-layer forming coil. After the stator core is pressed, the wire is inserted on the outside of the frame. The outer circle of the coil end is fixed with a metal end band of tying insulation, and the end is plugged tightly between the coil and the filler space, which increases the overall stiffness of the coil to prevent the coil from deforming when the motor is started or run. After the end of the coil is wired, the whole set
The sub-inlay part was treated with vacuum pressure impregnated solvent-free paint (VPI), and the painted stator inlay was finally loaded into the frame and fixed with it.
The rotor structure of the standard design is copper bar structure, and the rotor cage bar is copper or copper alloy according to the starting conditions. The advanced welding technology ensures the good connection between the cage bar and the end ring, so that the overall mechanical properties of the guide bar and the end ring are excellent and the electrical conductivity is good. The rotor cage bar and the rotor groove are expanded and tightened to eliminate the loose rotor cage bar in the groove caused by electromagnetic force and centrifugal force
The motor vibration problem not only prevents the rotor from breaking, but also prolongs the life of the motor.
 The rotor of the motor with the center height below H500 can also be cast aluminum structure. The rotor guide bar of this rotor structure is closely combined with the groove wall, which is more conducive to the rotor heat dissipation, prolongs the motor''''s allowable blocking time, and increases the moment of inertia of the allowable dragging load.
