The CEM D180L-6 is a three-phase induction motor built by CEM. The rated output is 15 kW. The motor is six-pole, which at 50 Hz gives a synchronous speed of 1,000 rpm. The rated voltage is 415 V. The housing is frame size 180 L in foot-mounted form. The protection class is IP55. The efficiency is 89 per cent at full load, 89.7 per cent at 75 per cent load and 88.2 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B5 and B35. The motor is built in China. The data is based on the Australian MEPS registration under standard AS/NZS 1359.5:2000 (Legacy); measured to IEEE 112-B(USA). Rated output across the CEM range ranges from 0.75 to 90 kW; the D180L-6 sits in the lower part of that range with 15 kW. Its immediate neighbours are the D160M1-2 below it with 11 kW and the D160L-2 above it with 18.5 kW. 54 CEM models are on record. The model is listed under Electric motors. 22 verified figures from 1 source are on file.

CEM – other models: the collective page of MEPS-registered three-phase motors outside the named D series, frame sizes 80 to 315, 0.75 to 90 kW, 2- to 6-pole, all IP55, manufactured in China

This page brings together the three-phase motors from CEM that the Australian energy-efficiency register (GEMS/MEPS) does not assign to a named series. Type designations such as D100L-2 or D160M1-4 follow the widespread IEC logic: the series prefix D is followed by the standard frame size from 80 to 315, a letter for the frame length (S short, M medium, L long), for some frame sizes an additional digit for winding or connection variants, and after the hyphen the pole count.

The register lists here 54 versions with 0.75 to 90 kW, two- to six-pole, at a supply voltage of 415 V. Efficiency at full load ranges from 72.5 to 94.2%, and at 75% load from 73.6 to 94.2%. All 54 motors are manufactured in China, carry the IP55 enclosure rating and are mounted to codes B3, B5 or B35. Testing followed AS/NZS 1359.5:2000 (Legacy) using test method A; none of the motors reaches a High Efficiency classification under GEMS.

The page thus shows the broad base programme with which CEM supplies standard three-phase motors for pumps, fans, conveyors and similar drive tasks in the volume segment. Against larger suppliers of standardised IEC motors, the range mainly covers the lower to mid power band up to 90 kW, with a consistent IP55 rating suitable for dustier environments too.

When buying used or replacing a unit, check the condition of the rolling bearings, a measured winding insulation resistance, visible overheating marks on the terminal box and fan cover, and a legible nameplate showing frame size, pole count and enclosure rating. Since none of the motors carries a High Efficiency classification, it is worth checking actual energy use under continuous duty before buying; bearings and terminal boxes for the IEC frame sizes are usually available independent of the manufacturer.

Frequently asked questions

How much power does the CEM D180L-6 have?

The CEM D180L-6 delivers 15 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.
