The Bonfiglioli BX80B4 is a three-phase induction motor built by 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 M in foot-mounted form. The protection class is IP54, IP55 and IP56. The efficiency is 82.8 per cent at full load, 83.5 per cent at 75 per cent load and 81.8 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B5, B14, B34 and B35. 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). Rated output across the Bonfiglioli range ranges from 0.75 to 30 kW; the BX80B4 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 – other models: the collective page of MEPS-registered three-phase motors from the Bologna gearmotor maker outside the named ranges, frame sizes 80 to 200, 0.75 to 30 kW

This page gathers the Bonfiglioli three-phase motors the Australian energy-efficiency register could not assign to a named range. Bonfiglioli was founded in 1956 and is headquartered in Calderara di Reno near Bologna; the company is best known for gearmotors and drive technology, and supplies the three-phase motors listed here both as a standalone BN range and as a drive component for its gear programmes. Designations such as BN132MA4 or BN160L2 follow the scheme of range code BN, IEC frame size and a letter-digit code for length and pole count; the BE codes (BE132MB4, BE160L4) point to combinations with the ME gear range.

The register lists here 44 versions with 0.75 to 30 kW, two- to six-pole, full-load efficiencies from 72.4 to 94.2% and at 75% load from 72.4 to 94.1%. Protection is mostly IP55, alongside combinations with IP54 and IP56; frame sizes run from 80 to 200. Italy and, in a few cases, combinations with Vietnam are recorded as manufacturing countries. Testing mostly followed the older AS/NZS 1359.5:2000 standard and the 2019 GEMS determination; only 7 of the 44 motors carry any documented High Efficiency classification at all, 5 at the 2018 level and one at the 2005 level.

Bonfiglioli is one of the large Italian drive-technology makers and competes with SEW-Eurodrive and Nord Drivesystems for applications in conveying technology, packaging machinery and mobile equipment; the motors on this collective page supplement the extensive BN range with older and rarer frame sizes.

When buying used, what matters is bearing condition and a checked insulation resistance of the winding, visible corrosion on the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with range, frame size and efficiency class; since only a small share of the models carry a High Efficiency classification, inverter suitability should be checked case by case. Spares run through the Bonfiglioli service network.

Frequently asked questions

How much power does the Bonfiglioli BX80B4 have?

The Bonfiglioli BX80B4 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.
