Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A method of installing a collector ring onto a rotor and terminating a collector ring lead comprising the steps of: (a) providing a rotor having a receiving means for receiving a collector ring lead, a rotor winding wire, and a terminal means; (b) inserting a rotor winding wire into the receiving means; (c) inserting a terminal means for electrically connecting a collector ring lead and the wire into said receiving means such that the terminal means electrically contacts the wire; (d) providing a collector ring having a collector ring lead structurally and electrically interconnected thereto; and (e) inserting the collector ring lead into the terminal means and the receiving means so that the collector ring lead makes electrical contact with the terminal means and the wire and the collector ring is structurally connected to the rotor.
Claim 2
Independent Claim
136 words
A method of installing a collector ring onto a rotor and terminating a collector ring lead comprising the steps of: (a) providing a rotor having a receiving means for receiving a collector ring lead, a rotor winding wire, and a terminal means; (b) inserting a rotor winding wire into the receiving means; (c) inserting a terminal means for electrically connecting a collector ring lead and the wire into said receiving means such that the terminal means electrically contacts the wire; (d) providing a collector ring having a collector ring lead structurally and electrically interconnected thereto; and (e) inserting the collector ring lead into the terminal means and the receiving means so that the collector ring lead makes electrical contact with the terminal means and the wire and the collector ring is structurally connected to the rotor.
Claim 3
Dependent Claim
45 words
A method in accordance with claim 1, wherein the step of providing a rotor comprises a rotor end cap having a slotted terminal receiving means mounted thereto, said terminal receiving means capable of receiving the wire end, a poke-in terminal, and the collector ring lead.
Claim 4
Dependent Claim
39 words
A method in accordance with claim 2, wherein the step of inserting a terminal means comprises inserting the poke-in terminal into the terminal receiving means such that an electrical connection between the poke-in terminal and the wire is formed.
Claim 5
Dependent Claim
48 words
A method in accordance with claim 3, wherein the step of providing a collector ring comprises pressing the collector ring into structural contact with the rotor end cap so that the collector ring lead electrically contacts the poke-in terminal and the wire in the slotted terminal receiving means.
Claim 6
Independent Claim
121 words
A method of installing a collector ring onto a rotor and terminating a collector ring lead comprising the steps of: (a) providing a rotor end cap having a slotted terminal receiving means mounted thereto, said terminal receiving means capable of receiving a wire, a poke-in terminal, and a collector ring lead; (b) inserting a magnet wire into the terminal receiving means; (c) inserting a poke-in terminal having a slot into the terminal receiving means; (d) displacing the insulation of the magnet wire to form an electrical contact between the magnet wire, and the poke-in terminal; and (e) inserting the collector ring lead into the terminal receiving means to form a structural and electrical interconnection between the rotor and the collector ring.
Claim 7
Independent Claim
121 words
A method of installing a collector ring onto a rotor and terminating a collector ring lead comprising the steps of: (a) providing a rotor end cap having a slotted terminal receiving means mounted thereto, said terminal receiving means capable of receiving a wire, a poke-in terminal, and a collector ring lead; (b) inserting a magnet wire into the terminal receiving means; (c) inserting a poke-in terminal having a slot into the terminal receiving means; (d) displacing the insulation of the magnet wire to form an electrical contact between the magnet wire, and the poke-in terminal; and (e) inserting the collector ring lead into the terminal receiving means to form a structural and electrical interconnection between the rotor and the collector ring.
Claim 8
Dependent Claim
43 words
The method of claim 5, further comprising the step of inserting an insulating substance into the terminal receiving means so that the electrical contact between the collector ring lead, the poke-in terminal, and the magnet wire is insulated from the air and environment.
