Overview:

Y, YR (IP23, IP44 Pipeline Ventilation), YKS, YRKS (IP44, IP54), large three-phase asynchronous motors with center height H710-1000, are new products developed based on advanced foreign motor technology in accordance with GB/T13957-92 standards. Computer-aided design (CAD) is used in the design, along with new materials and processes, featuring low noise, minimal vibration, high efficiency, energy saving, light weight, reliable performance, and easy installation and maintenance. Widely used in power plants, waterworks, petrochemical, metallurgy, mining, and other industries.

The Y and YR series are basic series with protection ratings of IP23 or IP44 (pipe ventilation). The base is made of steel in a popular box-type structure both domestically and internationally, offering lightweight and good rigidity. Various motors with different protection ratings or cooling methods can be derived. The YKS and YRKS series are air-water cooled three-phase asynchronous motors derived from the Y and YR series.

The rated voltage of the electric motor is 6000V, 10000V.

The squirrel-cage rotor winding of the Y, YKS series utilizes advanced welding technology and is made of copper busbars. The shaft is typically a single extension, but can also be manufactured as a double extension upon request.

The YR and YRKS series motors feature a cylindrical shaft extension, connected with tangential keys. They can also be manufactured with flat keys upon customer request.

Bearings utilize end cover spherical sliding bearings, offering strong load capacity and easy maintenance.

The main outlet box is designed according to the German DIN standard with a protection grade of IP54. It is typically mounted on the right side of the motor (when viewed from the main shaft extension) but can also be installed on the left side as per customer requirements. For motor power ratings above 2000KW, an auxiliary outlet box is provided on the opposite side of the motor to lead out the neutral point of the stator three-phase wire set.

Ventilation is by natural ventilation cooling, and can also be made into pipe ventilation, air-air cooling, and air-water cooling.

The motor stator winding assembly is equipped with six Pt100 embedded temperature sensing elements, each shaft bearing is fitted with a Pt100 temperature sensing element for monitoring purposes.
