Abstract

905,148. Insulation for dynamo electric machines. BOSCH G.m.b.H., ROBERT. April 7, 1961 [April 9, 1960], No. 12605/61. Class 35. An electric motor in which at least one end of the stator winding 14a, 14b is covered by a strip of insulating material 15 wound in the circumferential direction of the stator, the edge of the strip extending beyond the end of the winding in an axial direction and being folded inwardly against the pole bore and held there by an insulating tube 20 fitted into the space formed by the end of the stator winding so that it is coaxial with the pole bore. The motor, which is for a portable tool, has a shorted armature and is fed from a three-phase high-frequency supply.
