What is YE3/YE4 Three-phase Asynchronous Motor?

YE3/YE4 -series motor is totally enclosed squirrel-cage rotor ultra high efficiency, super ultra high efficiency three-phase asynchronous motor, it is widely used in the general use of all kinds of commonly use machinery and equipment, such as metal cutting machine tools, blowers, pumps, pressure molding machine and other mechanical drive, it is a Ideal products for Energy saving and emission reduction.

The power rating and assembling dimension of YE3/YE4 -series motor is in according with IEC international standard, same with the Germany DIN2673 standard, the protection grade of motor is IP55, cooling mode IC411, duty continuously (S1). Testing mode of the losses and efficiency for the motors according to IEC 60034-2-1-2016, efficiency targets according to IEC60034-30-1-2014.

The rated voltage of this 3-phase asynchronous motor is 380V, rated frequency 50Hz. The atitude of the motor should not exceed 1000 m; Ambient air temperature changes with the seasons, but no more than 40 ℃, the lowest air temperature should not lower than -15℃.

The Motor can be derived according to the user's requirements. 1. The different voltage, different frequency .Biaxial stretching. Dry (wet) special requirements such as tropical type motor. 2. The machine can according to user requirements to provide winding temperature measuring device, temperature of the stator winding temperature switch, bearing temperature measuring device, winding heating zone, etc.

The main difference between YE3 and YE4 is that the energy efficiency grade is different, that is, the efficiency is different. YE4 grade is higher than YE3, which means power saving. There are very few factories in China that can produce YE4. Only this kind of technology can really manufacture the motor of the ultra-efficient three-phase asynchronous motor YE4.
