The BE 80B 4 belongs to the BE series from Bonfiglioli. The rated output is 0.75 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The housing is frame size 80. The protection class is IP54, IP55 and IP56. The efficiency is 80.5 per cent at full load, 80.5 per cent at 75 per cent load and 77.6 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B5 and B14. Stated countries of manufacture: Italy and Vietnam. The values are recorded in the Australian MEPS registration under the GEMS Determination 2019; measured to IEC 60034-2-1 (Edition 2.0). The BE series covers 21 models. Rated output within it ranges from 0.75 to 22 kW; the BE 80B 4 sits at the bottom of that range with 0.75 kW. Its immediate neighbours are the BE 90S 4 above it with 1.1 kW. 71 Bonfiglioli models across 3 series are on record.

Bonfiglioli BE – the Italian three-phase motor range from Italy and Vietnam, exclusively four-pole, frame sizes 80 to 180, 0.75 to 22 kW, foot and flange versions

Bonfiglioli, founded in 1956 near Bologna, is one of the large Italian makers of geared motors and electric motors. The BE range gathers the maker's three-phase motors in the small and medium IEC frame sizes; type designations follow the scheme of frame size, build length and pole count, such as BE 132MA 4 for frame size 132, length MA, four-pole, in part supplemented with a voltage rating such as BE 100LA 4 240/415-50. Alongside the standard foot version, the register also lists flange variants, for example for frame sizes 100 and 160M.

The register lists here 21 versions with 0.75 to 22 kW, uniformly four-pole, full-load efficiencies from 80.5 to 91.6% and at 75% load from 80.5 to 92.3%. Frame sizes run from 80 to 180, protection is IP54, IP55 and IP56. Manufacturing is in Italy and in a combination of Italy and Vietnam, testing mostly used test method A under the 2012 and 2019 GEMS determinations.

Bonfiglioli positions the BE range as a classic three-phase motor for the European and Australia-Pacific markets, often paired with its own gear units into complete drive assemblies for conveyors, agitators and general industrial applications.

When buying used, bearing condition and a checked insulation resistance of the winding, the condition of shaft and key, visible corrosion on the terminal box and fan cover, and a legible nameplate with frame size, build form (foot or flange) and voltage rating matter; on flange versions, the condition of the centring to the mating part should also be checked. Spares and service run through Bonfiglioli's distribution network.

The Bonfiglioli BE 80B 4 delivers 0.8 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.
