Abstract

In a coreless coil type cylindrical air gap dc motor, a ring flange is provided. Connections to the coil are formed in the ring flange by conductor paths in the form of stamped metal strips lying in a plane. The conductor paths in turn have connecting tongues which are directed radially with respect to the ring flange.
