YBEJ Series Explosion-proof Electromagnetic Brake Three-phase Asynchronous Motors (H63~355)

1. General Description

       YBEJ series of flame-proof electromagnetic brake three-phase asynchronous motors (H63~355) are totally enclosed, fan-cooled, squirrel-cage motors as well as attached with D.C. braker. This series of motors have the characteristics of quick brake, accurate positioning, simple structure, convenient operation and easy maintenance, they are widely used in various machineries which require quick stop, accurate position and slide prevention on reciprocation. 

       This series of motors are suitable to be used as driver in the factory with explosive gas mixture. 

       This series of motors conform to the standard GB3836.1 <<Explosive atmosphere- part 1: Equipment-General requirements>>, GB3836.2 <<Explosive atmosphere- part 2: Equipment protected by flameproof enclosures “d”>>. They are made into explosion-proof types of ExdIIAT4 Gb and ExdIIBT4 Gb

       This series of motors have been approved the certificates of IECEx and EU ATEx.
