YBX4 Series High-Efficiency Explosion-Proof Three-Phase Asynchronous Motor |
| ¡öProfile |
¡¡¡¡YBX4£¨H80¡«355£©Series High-Efficiency Explosion-Proof Three-Phase Asynchronous Motor is a fully enclosed fan-cooled high-efficiency three-phase asynchronous motor successfully developed by our company in combination with domestic and foreign current new technologies in such aspects as electromagnetic structures, processes and materials when participating in a joint design of the Chinese explosion-proof motor industry.The efficiency indexes of this series conform to Motor Efficiency Level 2 in GB 18613-2020: Minimum allowable values of enery efficiency and values of efficiency grades for motors,and are in conformity with IE4 in IEC60034-30.Its power rating and installing dimensions conform to IEC and are the same as those of YB2¡¢YB3 and YBX3 series of motors.
This series complies with GB/T 755-2019: Rotation electrical machines-Rating and performance. Its explsdion-proof performance conforms to provisions in GB/T 3836.1-2021: Explosive atmospheres-Part 1:Equipment-General requirements, and GB/T 3836-2-2021: Explosive atmospheres-Part 2:Equipment protection by flameproof enclosures¡°d¡±,and ExdbI Mb,ExdbIIAT4 Gb,ExdbIIBT4 Gb and ExdbIICT4 Gb are applicable for hazardous environments with explosive gases within temperature groups T1¡«T4 in coal mines (non-mining faces) and factories with IIA,IIB and IIC.
This series can also be made into Humid tropical YBX4-TH,Dry tropical YBX4-TA,Outdoor type YBX4-W and
outdoor medium corrosion resistant YBX4-WF1,Outdoor strong corrosion resistance YBX4-WF2,Outdoor humid tropical YBX4-THW,Outdoor dry tropical YBX4-TAW, Tropical YBX4-T,Outdoor tropical YBX4-TW,Indoor medium corrosion resistant YBX4-F1 and Indoor strong corrosion resistant YBX4-F2
