Abstract

A common type of servo motor 10 employed in computer peripheral devices, such as serial printers and disk drives, includes a stator 12 and a rotor 14. In order to improve the heat dissipation of the motor, a bank of stamped snap rings 16 are snapped about the stator housing in the manner shown in the drawings. Each ring 16 has extruded spacer elements 18 so as to achieve a desired spacing between the rings. Each ring further has fins 20 to aid in convective heat dissipation. The rings 16 are removable in order to remagnetize the motor. When mounted, the rings 16 are in intimate metal~to-metal contact with the stator housing due to the spring action of the rings.
