Means for aligning coil injection tooling with a stator core

Claim 2

In tooling for placing prewound coils into selected slots of a magnetic stator core, the improvement comprising in combination: a plurality of elongated upstanding thin-walled members for receiving the prewound coils, each having a substantially uniform cross-sectional configuration for at least a distance equal to the stack height of a stator core in which the coils are to be placed; and means for aligning an internal surface of a stator core and said members to thereby allow the placement of a stator core onto said members for subsequent insertion of the coils into selected stator slots, said means for aligning being movable relative to the thin-walled members.

Claim 3

The improvement of claim 1 wherein each member is adapted to fit around a single stator tooth, further comprising means for simultaneously moving the members along respective stator teeth prior to the insertion of the coils into selected stator slots.

Claim 4

In tooling for placing prewound coils into selected slots of a magnetic stator core, the improvement comprising in combination: a plurality of elongated upstanding thin-walled members for receiving the prewound coils, each having a substantially uniform cross-sectional configuration for at least a distance equal to the stack height of a stator core in which the coils are to be placed; and means for aligning an internal surface of a stator core and said members to thereby allow the placement of a stator core onto said members for subsequent insertion of the coils into selected stator slots; said means for aligning comprising a peripherally notched tool adapted to pass through a stator bore with each notch accepting a corresponding stator tooth and to pass at least part way into the plurality of members with each notch accepting for less than the entire length of such notch a corresponding elongated member whereby the tool may be placed onto the upstanding members and a stator then placed thereover to engage the members.

Claim 5

In tooling for placing prewound coils into selected slots of a magnetic stator core, the improvement comprising in combination: a plurality of elongated upstanding thin-walled members for receiving the prewound coils, each having a substantially uniform cross-sectional configuration for at least a distance equal to the stack height of a stator core in which the coils are to be placed; and means for aligning an internal surface of a stator core and said members to thereby allow the placement of a stator core onto said members for subsequent insertion of the coils into selected stator slots; said means for aligning comprising a peripherally notched tool adapted to pass through a stator bore with each notch accepting a corresponding stator tooth and to pass at least part way into the plurality of members with each notch accepting for less than the entire length of such notch a corresponding elongated member whereby the tool may be placed onto the upstanding members and a stator then placed thereover to engage the members.

Claim 6

The improvement of claim 3 wherein each member is adapted to fit around a single stator tooth, each tool notch lying between a pair of wedged shaped protrusions for facilitating the placement of the tool onto the members and between a pair of wedge shaped protrusions for facilitating the placement of a stator over the tool.

Claim 7

The improvement of claim 4 wherein the tool comprises a pair of superposed coaxial generally flat circular plates with one of said plates being slightly larger than the other to thereby form a ledge therebetween which prevents movement of the tool onto the members beyond the ledge.
