Abstract
A case retained external capacitor that can be installed onto the motor sleeve of an electric motor. The case retained capacitor includes a capacitor case having a mounting clip formed along its inner wall. The mounting clip is sized to be retained within an attachment slot stamped from the motor sleeve. The capacitor case receives a capacitor having lead wires that extend out of the capacitor case and into the interior defined by the motor sleeve. During construction of a motor utilizing the case retained capacitor of the present invention, the capacitor case is installed along the motor sleeve by sliding the mounting clip into the attachment slot formed in the motor sleeve. Once the capacitor case is in place, the end plate of the motor is installed to prevent separation of the capacitor case from the motor sleeve.
