Abstract

A fixture for forming components of a rotating electrical machine that includes a main body defining a cavity, having a closed end, configured to receive a stack-up of metal plates forming a rotor or a stator; an end cap assembly, removably coupled to an open end of the cavity, having at least one spring that applies force in an axial direction toward the closed end of the main body; and an inductive heating system having an inductive loop that receives electrical current from a source and heats the metal plates.

Claims (22)

1 . A fixture for forming components of a rotating electrical machine, comprising:

a main body defining a cavity, having a closed end, configured to receive a stack-up of metal plates forming a rotor or a stator;

an end cap assembly, removably coupled to an open end of the cavity, having at least one spring that applies force in an axial direction toward the closed end of the main body; and

an inductive heating system having an inductive loop that receives electrical current from a source and heats the metal plates.

2 . The fixture recited in claim 1 , wherein the stack-up of metal plates are carried by a mandrel that engages with the closed end.

3 . The fixture recited in claim 1 , wherein the stack-up of metal plates includes metal plates having an adhesive coating on each side of the plates.

4 . The fixture recited in claim 1 , wherein the stack-up of metal plates include apertures between an inner diameter of the plates and an outer diameter of the plates.

5 . The fixture recited in claim 1 , wherein the stack-up of metal plates includes an adhesive coating comprising epoxy.

6 . The fixture recited in claim 1 , further comprising one or more adjustable stud(s) that control an amount of force exerted by the spring(s).

7 . The fixture recited in claim 1 , further comprising grooves formed in an outer surface of the fixture that are configured to engage a base that holds the fixture vertically.

8 . The fixture recited in claim 1 , further comprising a pivot linking the end cap assembly with the main body.

9 . A fixture for forming components of a rotating electrical machine, comprising:

a main body defining a cavity configured to receive a stack-up of metal plates forming a rotor or a stator;

a closed end coupled to an end of the cavity;

an end cap assembly, removably coupled to an opposite end of the cavity, having a plurality of springs carried by adjustable studs that apply force in an axial direction toward the closed end of the main body; and

an inductive heating system having an inductive loop that receives electrical current from a source and heats the metal plates.

10 . The fixture recited in claim 9 , wherein the stack-up of metal plates are carried by a mandrel that engages with the closed end.

11 . The fixture recited in claim 9 , wherein the stack-up of metal plates includes metal plates having an adhesive coating on each side of the plates.

12 . The fixture recited in claim 9 , wherein the stack-up of metal plates include apertures between an inner diameter of the plates and an outer diameter of the plates.

13 . The fixture recited in claim 9 , wherein the stack-up of metal plates includes an adhesive coating comprising epoxy.

14 . The fixture recited in claim 9 , further comprising grooves formed in an outer surface of the fixture that are configured to engage a base that holds the fixture vertically.

15 . The fixture recited in claim 9 , further comprising a pivot linking the end cap assembly with the main body.
