Procurement fit

Procurement specifications for the WEX3 series cover Ex db/eb IIB, IIC and I M2 Ex db I Mb motors in IEC frame sizes 80 through 350, with power output from 0.18 to 375 kW, certified to ATEX and IECEx requirements. The WEPM series covers variable-frequency speed-regulating permanent magnet motors from 0.18 to 315 kW, rated IE4 as documented, with IE5 also referenced for VFD-duty industrial drives. Both series address direct procurement of low-voltage industrial motors for hazardous-area and variable-speed applications.

Technical capabilities

The WEX3 series delivers low-voltage explosion-proof induction performance in IEC 80-350 frames with output from 0.18 to 375 kW, suitable for gas groups IIB, IIC, and mining group I M2. Protection types include flameproof Ex db and increased safety Ex eb. The WEPM series provides variable-frequency speed-regulating permanent magnet synchronous operation from 0.18 to 315 kW at IE4 efficiency, with IE5 also indicated for VFD duty. Both product lines are documented as low-voltage industrial machines.

Markets and applications

The documented specifications indicate the WEX3 series is intended for hazardous-area installations requiring ATEX or IECEx certified equipment, including surface industries handling gas groups IIB and IIC and underground mining (group I M2). The WEPM series is documented for VFD-duty industrial drives requiring variable speed regulation. Specific end-market verticals, named customer installations, regional sales distribution, and application case studies are not publicly documented in the available material.

Evidence limitations

This entry is limited to the WEX3 explosion-proof series and the WEPM VFD-duty series. Company founding year, manufacturing facility count, employee headcount, revenue, and global ranking are not publicly documented. Specific certifications beyond ATEX and IECEx are not publicly documented. Application case histories, installed base size, and named end-user references are not publicly documented. Service network coverage, lead times, warranty terms, and pricing structure are not publicly documented. The 2023 Exro partnership announcement is context only and is not treated as a specification.

Editorial summary

Wolong Electric Group is a China-based manufacturer documented in this directory under two product categories: explosion proof motor and vfd duty motor. The explosion proof line is represented by the Wolong WEX3 series low-voltage explosion-proof induction motors. The variable frequency drive line is represented by the Wolong WEPM series VFD permanent magnet synchronous motors. Documentation covers the WEX3 and WEPM designations as the current series references for each category. No additional series, frame sizes, or product families are recorded in the available material for this entry.

Frequently asked questions

What Explosion-Proof Motor product is documented for Wolong Electric Group?

The retained product material names Wolong WEX3 series low-voltage explosion-proof induction motors. The dossier keeps this as a product-level statement rather than using it as a claim about the company's entire catalogue. [S3]

Research notes

The retained first-party packet supports a richer product-level reading surface, but it does not yet contain 600 words of distinct cited content. This noindex dossier remains in reviewing status until additional source-backed facts are retained.
