Frequently Asked Questions
What are the primary applications for YBX4 series motors?
YBX4 series three-phase explosion-proof squirrel cage motors are primarily designed for hazardous environments such as coal mines, oil and gas, petrochemical, and chemical industries. They are also widely used in metallurgy, textile, city gas, transportation, medicine, and food processing.
What is the rated power and voltage range of the YBX4 series?
The rated power range spans from 0.12kW to 315kW, corresponding to Stand Nos 63 to 355. Available rated voltages include 380V, 660V, 380/660V, 400V, 690V, and 400/690V. The basic voltage of 3kW and below is Y connection, and above 3kW is △ connection. Special voltages are customizable.
What is the protection level and insulation class of these motors?
The motors are constructed with a protection rating of IP55 to prevent ingress of dust and water, and they feature a high-reliability insulation grade of 155 (Grade F) and an operation mode of S1 (continuous duty).
Which execution standards do the YBX4 motors comply with?
They conform to various major industry standards, including GB 755 (rotating motor performance), GB/T 1032 (testing methods), GB 3836.1 and GB 3836.2 (explosive environments specifications), and GB 18613-2020 for motor efficiency limits.
What explosion-proof markings do YBX4 motors carry?
These motors carry the official marks ExdllBT4Gb and ExdllCT4Gb, certifying their safe operation and flameproof capabilities within specific gas explosive atmospheres.
Are there optional configurations for extreme outdoor environments?
Yes. While the standard design is for indoor household use, optional configurations include outdoor (W), medium anticorrosion (WF1), strong corrosion (WF2), humid belt (TH), dry zone (TA), as well as combined outdoor humid/dry zones (THW/TAW).
