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.

The coreless motor as described in claim 2, wherein the center of the closed end of the external housing is penetrated by the rotating shaft centered on the central axis, and wherein an edge of the through hole in the external housing has second concave notches around the through hole separated by multiple projecting convex tabs. 4. The coreless motor as described in claim 2, wherein a portion of the molded resin body is located outside the through hole in the end of the external holding, wherein the portion projects beyond the end of the external housing, and wherein the portion forms a long cylinder parallel to the central axis. 5. The coreless motor as described in claim 2, further comprising: an oil reserve that is formed in an inner surface of the molded resin body. 6. The coreless motor as described in claim 2, further comprising: an eccentric weight in the shape of a partial cylinder which is attached to the end of the rotating shift to constitute a vibrating motor of the silent call type. 7. The coreless motor as described in claim 2, further comprising: an eccentric weight in the shape of a partial cylinder, and an extension to the eccentric weight having the same outside diameter as the eccentric weight and an inside profile that avoids striking a projection of the molded resin body and bearing, a first length of the extension being a shorter measurement than a second length parallel to a central axis of the cylindrical projection of the molded resin body that projects beyond the end of the external housing. 8. The coreless motor as described in claim 1, wherein the center of the closed end of the external housing is penetrated by the rotating shaft centered on the central axis, and wherein an edge of the through hole in the external housing has second concave notches around the through hole separated by multiple projecting convex tabs. 9. The coreless motor as described in claim 8, wherein the second concave notches of the through hole are at one end of the external housing, and the projecting convex tabs are located between the second concave notches and parallel to the central axis, and wherein the second concave notches and the projecting convex tabs are unitarily formed using an extrusion press. 10. The coreless motor as described in claim 9, further comprising: an eccentric weight in the shape of a partial cylinder which is attached to the end of the rotating shaft to constitute a vibrating motor of the silent call type. 11. The coreless motor as described in claim 9, further comprising: an eccentric weight in the drape of a partial cylinder, and an extension to the eccentric weight having the same outside diameter as the eccentric weight and an inside profile that avoids striking a projection of the molded resin body and bearing, a first length of the extension being a shorter measurement than a second length parallel to a central axis of the cylindrical projection of the molded resin body that projects beyond the end of the external housing. 12. The coreless motor as described in claim 8, wherein a portion of the molded resin body is located outside the through hole in the end of the external housing, wherein the portion projects beyond the end of the external housing, and wherein the portion forms a long cylinder parallel to the central axis. 13. The coreless motor as described in claim 12, wherein the second concave notches of the through hole are at one end of the external housing, and the projecting convex tabs are located between the second concave notches and parallel to the central axis, and wherein the second concave notches
