Buyer's Digest

Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Ac Motors. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

The YBX4 series is a flameproof three-phase asynchronous AC motor with a squirrel-cage rotor and closed casing. The stated rated-voltage options are 380 V, 660 V, and 380/660 V, with a rated frequency of 50 Hz.

The motor is specified with IP55 protection, IC411 cooling, Class F insulation, continuous-duty S1 operation, and Ex db IIB T4 Gb explosion-proof grading. The listed speed options include 590 r/min, 970 r/min, 1475 r/min, and 2980 r/min, corresponding to different pole configurations.

The stated operating conditions include a maximum altitude of 1,000 meters, maximum ambient air temperature of 40 °C, power-frequency tolerance of 50 Hz or 60 Hz ±1%, and operating-voltage variation within ±5% of rated voltage.

The identifies low noise, small vibration, high blocking torque, and reliable operation as design characteristics. The series is described for electric-drive use in petroleum, chemical, and coal industries, including workplaces containing explosive gas mixtures covered by the applicable requirements.

Customized voltage, frequency, installation mode, higher-altitude, and higher-temperature solutions are stated as available.

Confirm the exact motor power, frame size, mounting arrangement, shaft details, terminal configuration, rotation requirements, ambient conditions, hazardous-area classification, and required documentation before purchase.

Buyers should also confirm the selected speed, rated voltage, frequency, delivery configuration, inspection requirements, packaging, lead time, warranty terms, spare-parts support, and whether the stated explosion-proof and CCC documentation applies to the exact motor configuration ordered.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
