A notching apparatus for notching both an outer lamination and an inner lamination from a single lamination blank at s single station using a single press device includes a multi-piece die assembly provides multiple outer slot punches, multiple inner slot punches, and a separator punch. The outer slot punch portion, inner slot punch portion, and separator punch portion of the multi-piece die assembly are all selectively positionable in respective punching positions and non-punching positions to facilitate a controlled notching operation.

A dynamoelectric machine has a rotor or stator which comprises a core with axial groups of flat, rectangular magnet mounting surfaces, each successive magnet mounting surface of a group being circumferentially offset by a common angle of axial rotation from the previous magnet mounting surface. A magnet is mounted on each magnet mounting surface; and each magnet has a flat surface for mounting and an opposing arcuate surface to help form a cylindrical surface. Each of the magnets has the shape, when viewed radially, of a parallelogram forming a skew angle with the axis corresponding with the rotational offset of the magnet mounting surfaces to define skewed slots between skewed magnetic poles extending the substantial axial length of the core. The core may comprise polygonal lamina with the flat polygon sides grouped to form the magnet mounting surfaces; or it may comprise circular lamina with a non-magnetic sleeve having the magnet mounting surfaces. The latter provides a larger but more even air gap.

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.

An improved laminated rotor assembly is disclosed which features a novel key/keyway design that prevents lamination reversal while permitting indexing of successive laminae for the distribution of dimensional variations thereof. There are multiple, symmetrically oriented keyways, each keyway having an identical asymmetrical profile. The symmetrical distribution of identical profile keyways permits indexing of successive laminae, and the asymmetrical keyway profiles prevent lamination reversal. In the preferred embodiment, two or three keyways are employed, each key and keyway being formed in the shape of a step having at least two different radial dimensions.

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.
