CEM Other models

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.
