| Developed from YB series motors, this series of motors are totally
enclosed,squirrel-cage explosion-proof three-phase asynchronous
ones.The number of polars and output power are changed through the
different connection of coils to meet the load requirement of
machines,to meet the load requirement of machines,to simplify the
speed system and to save the electric energy. The multi-speed motors are satisfied by the changement of polars.They have two-speed,,three-speed and fourspeed ones.the terminal box of the two-speed motors has six connection bolts,three-speed motors nine connection blts and the four-speed motors tweleve connection blots for the different polars and speeds. This series of motors are up to the National standard GB3836.2-2000 part 2 Explosion-proof Electrical Equipment for the Explosive Area-safety Electrical Equitpment"d".They have types of ExdllAT4,ExdllBT4 for coal mines and dangerous areas with explosive gas mixture to drive machines with changeable speeds. The main hull of the motors is at the protection degree IP44 or IP55,The terminal box at IP55.The cooling systemis IC411. Rated Voltage of the motors:380V Frequency:50HZ Way of working:continuons(S1) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
