YBBP series variable trequency adjustable-speed converter-fed flameproof three phase asynchronous motors

YBBP series variable frequency adjustable- speed converter fed flameproof three phase asynchronous motor is

designed on the basis of YB2 series flameproof motors. In order to achieve the purpose of energy saving and automatic

control in the system with frequency conversion device, YBBP series motor could adjust speed stepless. It has features as

squirrel cage type, reliable operation, and easy maintenance and so on. An independent cooling fan ensures the motor has

good cooling effect in different speed.

YBBP series motor are suitable for transmissions of different kinds, mainly used in coal, oil and natural gas,

petrochemical and chemical industries, usually used to drive pumps, fans, compressors and other transmission machinery.

YBBP series motor could marked as ExdI、Exd II AT4 or ExdIIBT4. Exd I is applied In the non-excavation working

condition and coal mine with methane or coal dust, ExdIAT4 and Exd IBT4 are applied in the condition of explosion-

proof gas compound with Factory II type, Grade A& B. temperature T1. T2, T3 and T4.
