Pain Points vs. Solutions

Your Challenge: High energy costs drain operational budgets in continuous-duty hazardous environments.

Our Answer: IE4 efficiency reduces power consumption by 3-5% compared to IE3 motors, cutting annual electricity expenses significantly.

Your Challenge: Frequent motor failures in explosive atmospheres cause dangerous downtime.

Our Answer: Triple explosion-proof certifications (Ex d I/IIB/IIC) with optimized heat dissipation ribs extend service life through lower temperature rise.

Your Challenge: Installation incompatibility during equipment upgrades.

Our Answer: Fully interchangeable mounting dimensions with YBX3 enable direct replacement without facility modifications.

FAQ

QWhat is the meaning of YBX4 and energy efficiency grade?

A:YBX4 is the 4th generation high efficiency flame proof three phase asynchronous motor. It has IE4 super premium efficiency (Grade 2 per GB 18613-2020), increased from YBX3 (IE3) by optimised electromagnetic design and decreased operational losses.

Q: What explosion proof markings does this motor has? Where may it be used?

A: Standard certification: Ex d I Mb for permanent equipment in coal mines and Ex d IIA / IIB / IIC T4 Gb for a flammable gas environment in factories. They find use in coal mines, petrochemical plants, paint spraying booths, pharmaceutical facilities, grain processing centers, metallurgical activities, and for driving fans, pumps, compressors and conveyors.

QWhat are the main technical parameters?

AFrame sizes span H80-H355. Power ranges from 0.18-375 kW. Pole options include 2/4/6/8 configurations. Standard voltages are 380V/660V/660/1140V at 50Hz, with custom 400V/440V/60Hz for export. Protection is IP55, insulation is F-class, cooling is IC411, and duty is continuous S1.

QWhat's the core difference between YBX4 and YBX3?

AEnergy efficiency jumps from IE3 to IE4, reducing power consumption 3-5% under identical loads. Optimized heat dissipation ribs create smaller temperature rises and longer lifespans. Noise and vibration decrease through compact casing improvements. Installation dimensions remain fully interchangeable for direct replacement.

QCan this motor work outdoors or in corrosive humid sites?

AStandard IP55 construction prevents dust and splashing water, suitable for indoor hazardous areas. You can order outdoor W type, anti-corrosion WF1/WF2, or tropical TH/THW coatings for rainy, damp, or chemically corrosive outdoor environments. Rain shields complement weatherproof configurations.
