Abstract
884,025. Cooling electric motors. OLYMPIA WERKE A.G. Jan. 5, 1960 [July 13, 1959], No. 324/60. Class 35. [lAso in Group XVI] An electric motor for a typewriter is cooled by air circulated by helical ribs e on the rotor. The ribs e are arranged with a course pitch so that each rib extends only part-way around the rotor, they may be held on the periphery by end plates, and they may be formed of synthetic material.
