Abstract
Abstract A motor stator having a salient pole magnetic core on which are wound coils of conductive wire incorporating an annular printed circuit board having a plurality of radially projecting terminals. The printed circuit board is secured directly to the projecting ends of the coils at one end of the core and the two wire ends of each coil are secured to pairs of adjacent terminals on the board. External electrical leads are then threaded through the core between the coils with one end of the respective leads electrically joined to terminals on the board.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
The method of providing electrical connections to a plurality of individual wire coils wound on a salient pole motor stator, comprising the steps of: bringing the two ends of the wire forming each coil out together at the same end of the coil, forming an annular shaped printed circuit board having a plurality of radially outwardly projecting terminals electrically interconnected by the printed circuit, positioning the annular board coaxially on one end of the stator against the ends of the coils from which the ends of the wires are brought out, wrapping and securing the wire ends of each of the individual coils to adjacent ones of the radial terminals of the circuit board, and attaching external leads to terminals on the board.
Claim 2
Independent Claim
123 words
The method of providing electrical connections to a plurality of individual wire coils wound on a salient pole motor stator, comprising the steps of: bringing the two ends of the wire forming each coil out together at the same end of the coil, forming an annular shaped printed circuit board having a plurality of radially outwardly projecting terminals electrically interconnected by the printed circuit, positioning the annular board coaxially on one end of the stator against the ends of the coils from which the ends of the wires are brought out, wrapping and securing the wire ends of each of the individual coils to adjacent ones of the radial terminals of the circuit board, and attaching external leads to terminals on the board.
Claim 3
Dependent Claim
21 words
The method of claim 1 wherein the external leads are passed through the stator between the coils from the terminal board.
Claim 4
Dependent Claim
51 words
The method of claim 1 wherein pressure-sensitive adhesive is applied to one side of the board before the board is positioned against the ends of the coils to hold the board in place on contact with the coil ends while the coil ends are wrapped and secured to the radial terminals.
