YB2 Series Explosion Proof Three Phase Asynchronous Motor

YB2 explosion-proof asynchronous AC motor is a kind of motor that can be used in flammable and explosive places, and does not generate electric spark during operation. It is a motor structure that does not generate arcs, sparks or dangerous high temperatures under normal operating conditions, and then takes some mechanical, electrical and thermal protection measures to further avoid arcing, sparking or under normal or approved overload conditions. The danger of high temperatures ensures the safety of explosion protection. It consists of 15 frames ranging from 63 to 355. with a wide power range from 0.12 to 315 KW, totally 82 specifications.

YB2 explosion-proof asynchronous AC motors are mainly used in coal, oil and gas, petrochemical and chemical industries. In addition, it is widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper, medicine and other departments. Explosion-proof motors are used as the main power equipment and are commonly used to drive pumps, fans, compressors and other transmission machinery.
