YBBPX3 variable frequency speed regulating EX three-phase asynchronous motor

This series of motors has the advantages of small size, light weight, compact design, safe and reliable operation, long life, easy installation, in line with environmental requirements and international standards.

This series of motors comply with the provisions of national standard GB3836.1 “Electrical Equipment for Explosive gas environment Part 1: General requirements” and GB3836.2 “Electrical equipment for Explosive gas environment Part 2: explosive proof type “d”. At the same time, the design of its explosive proof structure and parameters refers to IEC60079-1 “Structure and test of explosive proof housing of Electrical equipment” and EN50018 “Electrical equipment for explosive environment “d”. The motor is made of explosive proof type. The explosion-proof mark is Exd I, ExdⅡAT4, ExdⅡBT4, ExdⅡCT4, which are respectively suitable for the fixed equipment in coal mine and the factory with ⅡA class, ⅡB class, ⅡC class, and the temperature group is the explosive gas mixture of T1 ~ T4 group.

The frequency range of this series of motors is 5~50/60Hz; Speed regulation is achieved by frequency modulation.

When the cooling mode of this series of motors is 1C416, the explosion-proof axial flow fan with independent power supply is forced to cool. When the cooling mode is IC411, self-fan cooling with external fan rotating with the motor.
