Remco offer two models of 4 pole external rotor motor for use with the tangential fans shown on the previous page. These general use motors may of course be used in other applications.

XM-4-30A, with 30 watts output, is normally used on 100mm diameter fans up to 500mm in length.
The more powerful counterpart, XM-4-50A, with 50 watts output can drive fans up to 1000mm in length in both Heating and Air Conditioning Applications.

These two motors provide useful replacements for motors found in fan decks both in heating and in air conditioning units and are fitted with ball bearings. Shafts are 8mm diameter with 40mm extension to allow easy fitting to the commonly found rubber drive hub incorporated in the driven end of the fan impeller.
