Abstract
The present invention advantageously provides a cost effective flat rotor for a pancake type slip ring. A flat copper coil sheet is stamped into a corrugated shape having concentric V-ring grooves. The corrugated stamped copper foil sheet is bonded using a bonding agent to a dielectric layer. Multiple concentric V-grooves are formed by separating the grooves, for example, by machining the grooves at an apex thereof in order to form separate electrical circuits. A corresponding plurality of holes extend through each concentric ring and through the dielectric layer from the first side through the second side. A conductive material is placed in each of the plurality of holes to electrically connect each concentric ring to the second side.
Claims19
A rotor portion for a pancake slip ring, comprising:
- a dielectric layer having a first side and a second side;
- a plurality of concentric rings which extend 360°, with each concentric ring adjacent said first side of said dielectric layer;
- a corresponding plurality of holes extending through each of said concentric rings and through said dielectric layer from said first side through said second side;
- and
- a conductive material in each of said plurality of holes to electrically connect each of said concentric rings to said second side.
A rotor portion for a pancake slip ring, comprising:
- a dielectric layer having a first side and a second side;
- a plurality of concentric rings each adjacent said first side of said dielectric layer and bonded to said first side with a bonding agent;
- a corresponding plurality of holes extending through each of said concentric rings and through said dielectric layer from said first side through said second side;
- and
- a conductive material in each of said plurality of holes to electrically connect each of said concentric rings to said second side.
A rotor portion for a pancake slip ring, comprising:
- a dielectric layer having a first side and a second side;
- a plurality of concentric rings having a V-shaped cross-section which extend 360°, with each concentric ring adjacent said first side of said dielectric layer and bonded to said first side with a bonding agent;
- a corresponding plurality of holes extending through each of said concentric rings and through said dielectric layer from said first side through said second side;
