US Patent:

56441819, Jul 1, 1997

Filed:

Jan 5, 1995

Appl. No.:

8/369097

Inventors:

Gale A. Kooken - Englewood OH
John W. Murphy - Kettering OH
Roger D. Fleming - Centerville OH

Assignee:

Dayton-Phoenix Group, Inc. - Dayton OH

International Classification:

H02K 100

US Classification:

310216

Abstract:

A stator lamination for an electric motor includes a plurality of notches extending about an inner periphery thereof shaped to minimize damage to insulation of the conductor during insertion of the conductor into the notches and removal of the conductor from the notches. Each notch includes two side walls which intersect the inner periphery of the laminate at a tapered angle. The side walls each include a cutout shaped to receive a retaining strip or slat therebetween, and the cutouts intersect the walls at tapered angles. The tapered angles are preferably less than about 12. degree. or greater than about 14. degree. , in order to prevent the formation of a locking taper.

Assignee:

Dayton-Phoenix Group, Inc. - Dayton OH

International Classification:

B26D 314
B26D 706

US Classification:

83 23

Abstract:

The invention is a stator lamination jig system which comprises a centrally located spindle and a support for a stator lamination having a plurality of holes therein. The support is rotatively-mounted on the spindle for driving the lamination during a notching operation. A plate is included to secure the lamination on the support and a non-rotatable ejector is located below the support which has a lowered position and a raised position. An ejection cylinder is seated upon the ejector which is shaped and positioned to extend through holes in the support. The invention also comprises a cylinder connected to the ejector for driving the ejector. When the cylinder is actuated upwards, the ejector is in a raised position which urges the ejection cylinder through the holes in the support to cause the lamination to be released from the jig.
