Detailed Product Description

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 requiremeent of machines, to simplyfy the speed system and to save the electric energy.

The multispeed motors are satisfied by the changment of polars. Then have two-speed,three-speed and fore-speed ones. The terminal box of the two-speed motors has six connection bolts, three speed motors.

This series of motors are up to the National Standards GB3836.2-2000<Electrical apparatus for explosive gas atmospheres part 2:Flame-proof enclosure "d">.

The main hull of the motors is at the protection grade IP44 or IP54.

Rated voltage of the motors:380V

Frequency:50Hz

Way of working:contionuous(SI)
