US Patent:

47246022, Feb 16, 1988

Filed:

Apr 15, 1986

Appl. No.:

6/838467

Inventors:

Adrian M. Weissman - West Orange NJ

Assignee:

Universal Manufacturing Corporation - Paterson NJ

International Classification:

H01F 706

US Classification:

29605

Abstract:

The common winding of an autotransformer is formed in two sections connected electrically in parallel and one section overlying the other. One section is wound clockwise and the other is wound counterclockwise. This reduces the voltage difference between adjacent layers of the two sections, permits the use of a smaller wire, and results in cooler and more efficient operation.

Filed:

Sep 24, 1979

Appl. No.:

6/078333

Inventors:

Adrian Weissman - Jersey City NJ

Assignee:

The Singer Company - Stamford CT

International Classification:

H02P 306

US Classification:

318245

Abstract:

A universal series motor having its brushes shifted at an angle against the direction of rotation is provided with a braking arrangement which removes power from the field windings and applies power directly to the armature winding.

Filed:

Mar 31, 1988

Appl. No.:

7/175951

Inventors:

Adrian M. Weissman - South Orange NJ

Assignee:

MagnaTek Universal Manufacturing - Paterson NJ

International Classification:

H01F 1510
H01F 4110

US Classification:

336189

Abstract:

Disclosed is a coil including winding support means for supporting a base layer of wire including a first predetermined number of turns wound in a precision pattern about the support means. A wire tap layer is wound about the support means at an average pitch ratio substantially equal to a second predetermined number of turns for the tap layer divided into the first predetermined number of turns. A tap of wire is then taken from an end of said wire tap layer. Finally, a subsequent wire layer is wound over and in an opposite direction to the tap layer, wound at an average pitch ratio substantially equal to the first predetermined number of turns in the tap layer divided by the difference between the first predetermined number of turns and the second predetermined number of turns. The present invention is also directed to a method of winding a coil.
