ABSTRACT:
A modular motor end dome for an industrial electric fan motor has a motor capacitor, and is provided on the rear end with a protective axial cavity in which may be seated the threaded mounting stem and attachment nut of an internally mounted pull chain electric motor control switch. Alternatively, an external 2-speed electric motor control switch can be employed with the modular motor end dome and with a drop cord connecting the external 2-speed electric motor control switch to the motor capacitor mounted in the modular motor end dome, and with the drop cord entering the modular motor end dome through the protective axial cavity.
