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: 3
Claim 1
Independent Claim
148 words
In a motor stator having a cylindrical core of magnetic material defining a plurality of radial poles on which are wound coils of conductive wire, apparatus for connecting external electrical leads to the coils comprising: an annular printed circuit board having a plurality of integral radial projections around the outer periphery, the projections supporting a portion of the printed circuit to form a plurality of electrical terminals, there being two terminals for each coil, adhesive means holding the circuit board against the coils adjacent one end of the core and coaxial with the core, the two wire ends of each coil being wrapped around said projections and electrically connected to the associated terminals, the wire ends anchoring the board against the coils, and a plurality of external electrical leads connected to selected ones of said terminals, the printed circuit board electrically interconnecting the external leads and the coils.
Claim 2
Dependent Claim
