ABB M3BP – process performance motors in cast-iron frames: frame sizes 80 to 355, 0.75 to 185 kW, how to read the type code
M3BP is ABB's standard three-phase motor with a cast-iron frame for the process industries – pumps, fans, compressors and conveyors in chemicals, paper, water and mining. The type code follows ABB's system: M for motor, 3 for the generation, B for the cast-iron frame, P for 'process performance'. Then come the IEC frame size (shaft height in mm), the frame length letter (S, M, L with sub-variants A to F) and the number of poles – 'M3BP 132 SMB 4' is therefore a four-pole motor with a 132 mm shaft height in medium length. Trailing letters such as B, G or L mark the winding and voltage variant.

In the register the series comprises 364 versions from frame size 80 to 355 with rated outputs from 0.75 to 185 kW, two- to eight-pole. Full-load efficiencies run from 74.1 % on the smallest to 97.2 % on the large motors; the data come from energy-efficiency registrations that list efficiency at 50, 75 and 100 % load for each type. Protection is at least IP55 throughout, mostly optionally up to IP66, and mounting arrangements range from B3 (foot) through B5 and B35 (flange) to the vertical forms V1 to V6. Finland, Poland, India and China are recorded as manufacturing locations.
The cast-iron frame distinguishes the M3BP from its aluminium sibling M3AA: it is heavier, stiffer, more resistant to chemicals and allows higher bearing loads – the motors recorded in the register weigh 16 to 1,065 kg.
When buying or replacing, what matters is frame size and mounting (shaft height and flange dimensions are standardised in IEC 60072 and thus interchangeable between makers), the efficiency class to IEC 60034-30 (IE2 or IE3 depending on year and market) and suitability for inverter duty.

How much power does the ABB M3BP 250SMC2 have?
The ABB M3BP 250SMC2 delivers 90 kW.
What to check before buying
- Match the data plate against the order: frame size, mounting and rating have to agree.
- Check the ingress rating against the installation site — outdoors or in dust the demands differ.
- Hold the mounting form and dimensions against the existing seat before ordering.
- The pole count sets the speed — when replacing an older unit, compare this first.
- For used units, ask about winding condition and bearing play.
- Ask about parts availability for this series — the running costs hang on it.
