WEG Motor Cross Reference
WEG Motor Cross Reference - WorldWide Electric & NAE Equivalents
WEG's W22 platform is one of the most common cast iron motors in Texas plants, and their crusher duty units dominate aggregate sites. When the lead time doesn't cooperate, the NEMA nameplate crosses W-series motors straight onto stocked cast iron equivalents.
The Five-Point Cross
| Check | From the Old Nameplate | Must Match? |
|---|---|---|
| HP & RPM | Rated power and full-load speed | Yes - same HP (or one up), same pole count |
| Frame | NEMA frame number (e.g. 184T, 326T) | Yes - frame match = bolt-in fit |
| Voltage / Phase | e.g. 230/460V, 3φ, 60 Hz | Yes |
| Enclosure | ODP, TEFC, TEXP, washdown | Yes, or upgrade |
| Service Factor & Design | SF 1.15, NEMA Design B typical | Equal or better |
Because both brands build to NEMA MG-1, a frame match guarantees the mounting dimensions - details in our frame size chart and nameplate guide.
Where WEG Lines Typically Cross
| WEG Line | Duty | Our Equivalent Series |
|---|---|---|
| W22 general purpose / premium | Cast iron TEFC | PE Cast Iron TEFC |
| W22 severe duty / mining | Abusive environments | Severe Duty Cast Iron · Severe Duty PE |
| Crusher duty | Aggregate, quarries | Crusher Duty (to 600 HP) |
| Explosion proof (W22Xd…) | Classified areas | Explosion Proof |
| JM/JP pump | Close-coupled | Close-Coupled Pump |
| Washdown | Food & beverage | Washdown Stainless |
WEG Cross Notes
Two things to check on WEG nameplates: frames - WEG sells both NEMA and IEC builds; a W22 with frame 324/6T crosses directly, while an IEC 200L does not bolt to a NEMA base (adapters or IEC sourcing required). And voltage - imported spares sometimes carry 50 Hz or 380V ratings; a 60 Hz plant needs the 60 Hz winding, full stop.
WEG crusher motors often carry high-torque designs with roller bearings on the drive end for belt duty - our crusher duty lines mirror that construction; confirm bearing arrangement when the motor drives a heavy sheave.
Frequently Asked Questions
Do WEG W22 motors interchange with WorldWide Electric or NAE?
On NEMA-frame W22 units, yes - matching frame, HP, RPM, voltage, and enclosure yields a bolt-in equivalent under NEMA MG-1. IEC-frame WEG motors need IEC replacements or adaptation.
How can I tell if my WEG is NEMA or IEC?
Read the frame field: numbers like 213/5T, 326T are NEMA; 90S, 132M, 200L are IEC. Dimensions differ in both feet and shaft - the two systems do not mix without adapters.
What crosses a WEG crusher duty motor?
Dedicated crusher duty designs with high starting torque and heavy drive-end bearings, stocked to 600 HP. Match HP, RPM, frame, and voltage, and confirm the drive-end bearing type if the motor carries a large sheave load.
My WEG nameplate shows 380V 50Hz. What do I order for US service?
A 60 Hz motor wound for your actual bus - typically 230/460V three-phase. The 50 Hz rating means the machine was imported with its equipment; running it at 60 Hz shifts speed and torque, so replace with the correct 60 Hz rating.
Are your cast iron motors comparable to W22 efficiency?
Our premium efficient cast iron lines meet the same NEMA Premium table the W22 premium tiers target. Compare nameplate nominal efficiency on the specific rating - and weigh availability: an in-stock motor at equal efficiency beats a quoted lead time.
