ABSTRACT:
An apparatus (10) for cooling a ceiling mounted room fan motor (11) having a rotatable shaft (24) and a motor housing (12) includes a flywheel (13) supported upon and rotating with the shaft (24) and a fan assembly (14). Motor housing (12) has a cylindrical side (15) and substantially circular end plates (18, 19) which together completely seal all windings of fan motor (11) therewithin and preclude entry of and contamination by environmental particulate pollutants. Fan assembly (14), similar to that of a squirrel cage fan, is substantially cylindrical, surrounds motor housing (12), and is operatively connected with flywheel (13) to rotate with the shaft (24), all energy for operation of fan assembly (14) being provided by fan motor (11).
