Yb High Voltage Three-Phase Asynchronous Motor,High Efficient Explosion-Proof Motor, Ie3

Product overview

 YB series high-voltage three-phase asynchronous motor (frame number 355-630) is a high efficiency explosion-proof motor, which adopts the high technology introduced from Germany. With this new technology and advanced engineering materials, our products are characterized by compact structure, low vibration, low noise, good outdoor applicability and light weight. They meet the national IE3 standards and can be used in high-risk areas containing explosive gases.
IEC and German standards can be used as substitutes for auxiliary motors of export equipment and imported motors respectively.
