A 4 kW YE4 replacement needs two separate matches

The published Hengshui YE4 tables separate electrical performance from mechanical dimensions. Use the exact performance row to match speed and current; then use the drawing for the offered mounting form and shaft. These two checks cannot be replaced by an efficiency-class label or a shared frame number.

Same 4 kW output, different machine duty

These are two individual catalogue rows under the manufacturer's stated 380 V, 50 Hz conditions. They are comparison examples, not interchangeable options for one unchanged driven machine.

The 225M frame label also hides a shaft difference

In the separate dimension table, the D shaft dimension changes with pole count. This is a warning against ordering by frame alone, not a claim that every 225M variant has the same flange or shaft extension.

Two-pole 55 mm Existing coupling bore and the exact offered drawing
Four-, six- and eight-pole 60 mm Coupling bore, shaft extension and clearance on the offered drawing

What must be settled before approving the offer

Keep the electrical and mechanical decisions together in one model-specific offer. The maker lists B3, B5 and B35 forms; an installation cannot be signed off from the power rating alone.

For a replacement

Send the old nameplate, driven-machine speed and load, site supply, starting method, operating hours, mounting form and a dimensioned shaft/flange drawing. Ask the supplier to identify the exact YE4 row being quoted.

For a different supply

The table values above belong to 380 V and 50 Hz. For another voltage or 60 Hz, ask for a separate performance sheet for the offered winding; do not transfer the listed current and efficiency to that configuration.

For the efficiency claim

Request the offered model's test basis and applicable efficiency declaration. The catalogue's general IE4 positioning is not evidence that an unspecified winding or altered site supply meets a particular measured value.

CATALOGUE OVERVIEW

About this motor series

Hengshui Electric Motors publishes YE4 three-phase induction motors with model-table outputs from 0.55 to 315 kW. The table separates two-, four-, six- and eight-pole configurations, with model-specific current, speed, efficiency, power factor and starting-performance values. The catalogue states IC411 cooling, IP55 protection and class F insulation. Select the exact frame and pole count before comparing performance: the series range does not describe a single motor or guarantee every output in each configuration.
