Gamak Other models

The register lists here four versions with 2.2 to 11 kW rated output, four- to six-pole. The supply voltage for the majority of the motors is 400 V. Full-load efficiency ranges from 81.9 to 89.8%, and at 75% load from 81.7 to 89.3%. Frame sizes fall between 112 and 160, the protection class is IP55 throughout, and the mounting code is B3 throughout. Testing followed AS/NZS 1359.5:2004 with test method A.

With a power band from 2.2 to 11 kW and pole counts from four to six, the range covers the medium speed classes of classic three-phase standard motors, used on pumps, fans, conveyors and compressors; IP55 protection also suits dusty or damp industrial halls.

On a used purchase, bearing condition, a tested winding insulation resistance, the seals at the terminal box and shaft lead-through, and a legible nameplate with frame size, pole count and protection class all count. Anyone wanting variable-speed operation should check inverter compatibility. Spare parts run through the Gamak distribution network or general electric-motor suppliers.
