WPWD Flange-Mounted Universal Worm Gear Reducer — IEC Motor-Direct Drive Combined with Universal Multi-Orientation Base
The WPWD flange-mounted universal worm gear reducer combines two powerful features in a single cast iron unit: an IEC 60034-7 compliant motor flange that eliminates the coupling between motor and gearbox, and the WPW universal flanged-base platform that provides correct installation in multiple mounting orientations. This means faster motor installation (no coupling to assemble and align), plus the multi-orientation mounting flexibility that standard WP series motor-direct units cannot offer.
Accepting motors from 0.12 kW to 15 kW across 12 size groups (40–250 mm), the WPWD covers the full range of food processing, pharmaceutical, packaging, and general industry motor-direct drive requirements — all with the mounting angle freedom of the WPW universal platform. IEC flange dimensions: LA, LB, LC, LE, LZ per IEC 60034-7. About Ever-power | Request a Motor Compatibility Check

Product Structure — IEC Motor Flange + Universal Flanged Base
The WPWD housing integrates both the WPW universal flanged base (AC, BC, AD, BD, Z×L dimensions) and the IEC motor flange (LA, LB, LC, LE, LZ dimensions) in a single casting. The motor slides directly into the IEC bore at the input side; the flanged base provides multi-orientation rigid mounting at the structure side. Both features are integral to one housing — no separate baseplate, no motor-adapter plate.
| Motor Input | IEC 60034-7 flange; 0.12–15 kW; motor shaft direct, no coupling |
| Mount Base | Universal flanged base; 4 anchor bolt positions; multi-orientation |
| Orientations | Multiple positions (A–F); multi-face oil ports for each position |
| Housing | FC25 cast iron; both features integral — no separate motor plate |
| Output | Solid shaft with keyway; LS/S/W×Y per size |
| Self-Locking | At ratios ≥1/30 — passive load holding without separate brake |
✅ Key Features & Benefits
IEC Motor Direct + Universal Base — Two Features, One Housing
The WPWD uniquely combines the motor-direct convenience of an IEC flange with the universal multi-orientation mounting of the WPW flanged base. No other single product in the WP/WPW series delivers both features simultaneously. Keywords: IEC flange universal worm reducer, motor-direct multi-orientation worm gearbox.
Universal Mounting at Any Angle — No Coupling Alignment Required
The WPW universal base allows the WPWD to be mounted at any of its supported orientations. The IEC flange eliminates the coupling at the motor input. The result: a multi-orientation motor-direct drive with no coupling to align, no motor baseplate to shim, and no coupling guards to install — simplifying machine build time significantly.
Rapid Motor Replacement Across All Mounting Positions
The IEC pilot register enables motor swap in 15 minutes regardless of mounting orientation — whether the unit is horizontal, inclined, or vertical. For food processing and packaging facilities where motor failure during production must be corrected quickly, this rapid swap capability has direct commercial value across all WPWD mounting configurations.
0.12 kW to 15 kW — Widest Motor Range in Universal Series
Twelve size groups accepting motors from 0.12 kW (size 40, small indexing and positioning drives) to 15 kW (size 250, large conveyor and process drives) provide the broadest motor range available in the WPW universal series — from small food processing vessels to large packaging line conveyors.
Precision Gear Pair for Quiet Food & Pharma Service
Ground worm and bronze wheel to ISO 1328 Grade 7 deliver ≤72 dB(A) noise and smooth, uniform output — essential for food processing vessels, pharmaceutical equipment, and packaging machinery where gear-induced vibration affects product quality or production consistency.
Self-Locking in Multi-Orientation Service
At ratios ≥1/30, the WPWD self-locks in any mounting orientation — providing passive load holding that is consistent regardless of whether the unit is horizontal, inclined, or vertical. This makes the WPWD a complete, compact motor-direct drive solution without needing a separate backstop or brake in many applications.
Industry Applications
The WPWD is specified wherever motor-direct convenience must be combined with universal multi-orientation mounting flexibility:

❓ Frequently Asked Questions
What is the difference between WPWD and WPW?
The WPW has a standard solid input shaft requiring an external coupling to connect to the motor. The WPWD has an IEC motor flange allowing the motor shaft to connect directly to the input bore without a coupling — while retaining the same universal flanged-base platform as the WPW. Both products share the same flanged base dimensions and output shaft specifications; the input connection method is the sole difference.
Can I use any IEC motor with the WPWD?
The WPWD accepts any standard IEC 60034-7 frame motor whose LA, LB, LC, LE, LZ flange dimensions match the specified WPWD size group. For each size group, the matched motor power range is shown in the specification table (e.g. size 80 accepts 0.75 kW or 1.5 kW motors). Contact us with your motor nameplate details for a compatibility confirmation before ordering.
Does the WPWD support the same mounting orientations as the WPW?
Yes — the WPWD uses the same universal flanged base as the WPW and supports the same range of mounting orientations. Multi-face oil ports ensure correct gear lubrication in each position, and oil fill instructions for all rated positions are supplied with every WPWD unit. The IEC flange adds motor-direct input; it does not change the mounting orientation capability.
Is the WPWD available with food-grade lubricant for GMP applications?
Yes — on request, we factory-fill WPWD units with NSF H1 registered food-grade gear oil suitable for incidental food contact. Specify ‘food-grade lubricant’ in your purchase order. This is widely specified for WPWD units used in food processing vessel drives, beverage line conveyor drives, and pharmaceutical equipment in GMP-compliant facilities.
What is the maximum output torque of the WPWD?
At 1500 r/min input, size 250 with 15 kW motor at ratio 1/60 delivers approximately 3,025 Nm (from the WPD.WPDK.WPWD.WPWDK power and torque table). This is higher than the WPW equivalent because the WPWD uses a matched motor with the full power available rather than an externally coupled motor which may have coupling losses. Contact our engineers for a precise calculation for your motor power and ratio.
