Compressors get hot from the heat of compressed vapor. Therefore, in some applications, a fan is used to cool the compressor, especially low temperature refrigeration with reciprocating compressors. Typically a fan motor provides 20-55 W of output power, however, ECMs can provide this output more efficiently than shaded pole motors. Depending on the refrigerant being used and the temperature settings of the system, the fan may not be needed at all and can be simply removed. 

This measure replaces the existing shaded pole motor or permanent split capacitor with a more efficient Electrically Commutated Motor (ECM) on a compressor head fan.
