Y2 Series Low Voltage High Power Three Phase Asynchronous Motors (H: 355-560mm)

 

General Introductions 

Y2 series (H355-560) squirrel-cage low-voltage, high power three-phase asynchronous motors are made by our company absorbed from the merits of both domestic and foreign similar motors and using new materials and new processes. This series has the characteristics of artistically designed appearance, high performance indexes, high reliability, small size, low weight, slight vibration, low noise, high energy efficiency etc.

The performance, mounting dimensions, and output ratings of this series are in accordance with IEC72, GB755, JB/T10444, and other related professional and technical standards.

The protection class of this series1 enclosure is IP54 or IP55. The motors1 insulation grade is F, adopted vacuum pressure impregnation (VPI), which can effectively reduce the temperature rise and slow down insulation aging.

The standard cooling method for this series is IC411, and the mounting type is IMB3 and IMB35 in general.

The series needs 50HZ (or 60HZ as required) three-phase power supply that should provide the voltage of 380V or 660V. Its voltage class also can be customized according to users1 needs.


Structure Declaration 

Parallel vertical radiation ribs are adopted in the frame design, and the ventilating structure contains two separate cooling wind paths. Air external to the motor would be driven by an external fan to blow over the radiation ribs. Meanwhile, there are four ventilating ducts within the frame and the inner wind.

The path is formed by an internal fan and axial vents on rotor sheets. In this way, the heat dissipation efficiency is improved effectively. The external fan of 2-pole motors is a one-way tube-axial fan, whose direction of rotation is fixed, while motors with 4-8 poles are provided with a two-way radial centrifugal fan, whose direction of rotation can be arbitrarily selected.
Squirrel-cage copper-bar structure or cast aluminum structure is adopted in rotor design, and the vibration is very low after high-precision dynamic balance and motor running balance tests.  
The primary terminal box is mounted at the top of the frame and can be required on the left or right. It also could be mounted at a 45-degree angle according to users' needs.
