The Cosgra Cemer IE2-MSL 802-4 is a three-phase induction motor from the Cosgra Cemer range. 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 rated voltage is 400 V. The housing is frame size IM b3. The protection class is IP55. The efficiency is 80.5 per cent at full load, 79.7 per cent at 75 per cent load and 77.5 per cent at half load. The mounting arrangement to IEC 60034-7 is B3. The motor is built in Spain. The data is based on the Australian MEPS registration under standard AS/NZS 1359.5:2004; measured to IEC 60034-2-1 (Edition 2.0). Rated output within this group ranges from 0.18 to 1,119 kW; the IE2-MSL 802-4 sits at the bottom of that range with 0.75 kW. Its immediate neighbours are the TTW01 below it with 0.73 kW and the 3514167 above it with 0.9 kW.

Cosgra Cemer – other models: the collective page of MEPS-registered IE2 three-phase motors from Spain outside the named ranges, 0.75 to 1.1 kW, four- and six-pole, B3 mounting

This page gathers the Cosgra Cemer three-phase motors the Australian energy-efficiency register could not assign to a named range. Cosgra Cemer is a Spanish maker of three-phase motors; the designations recorded in the register, IE2-MSL 802-4 and IE2-MSL 90L-6, carry the IE2 code directly in the name and thereby mark the models as versions of the standard efficiency class under IEC 60034-30-1, followed by the frame size (80, 90L) and the pole count at the end (4, 6).

The register lists here 2 versions with 0.75 to 1.1 kW rated output, four- or six-pole, for a 400 V supply, with full-load efficiencies from 78.36 to 80.5% and at 75% load from 77.7 to 79.7%. Protection is IP55, the mounting form of both motors is B3 (foot type), testing followed AS/NZS 1359.5:2004 with test method A. Manufacturing takes place in Spain.

The IE2 efficiency class carried in the name corresponds under IEC 60034-30-1 to the standard efficiency for three-phase induction motors, below the IE3 class required in many markets for years; four- and six-pole motors of this small power class run at 1,500 or 1,000 rpm at 50 Hz and classically drive pumps, fans and slow-running conveying equipment where the lower speed suffices without a gearbox.

When buying used, bearing condition and a checked insulation resistance of the winding, the condition of the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size, pole count and the IE2 mark matter. Spares run through Cosgra Cemer's Spanish distribution.

The Cosgra Cemer IE2-MSL 802-4 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.
