PCT No. PCT/DE91/00378 Sec. 371 Date Feb. 5, 1992 Sec. 102(e) Date Feb. 5, 1992 PCT Filed May 8, 1991 PCT Pub. No. WO91/19346 PCT Pub. Date Dec. 12, 1991.An electrical machine has a surface-cooled stator having two stator plate stacks provided with slots and two stator windings arranged one after the other in an axial direction and inserted in the slots of the stator plate stack, a drive shaft, two pole systems cooperating with the stator windings, a metal housing arranged so that winding ends of the stator windings project outwardly beyond the metal housing and the two plate stacks are enclosed by the metal housing and fitted in the latter so as to conduct heat. The two stator plate stacks are offset relative to one another by half a slot spacing and, together with the winding ends of the stator windings are embedded in heat conducting plastic to form a prefabricated construction unit.
