44986360, Feb 12, 1985

Filed:

Feb 25, 1982

Appl. No.:

6/352349

Inventors:

Chester C. Boesewetter - Radford VA
Lawrence W. Langley - Christiansburg VA
John H. Mabie - Radford VA

Assignee:

Kollmorgen Technologies Corporation - Dallas TX

International Classification:

B65H 5410

US Classification:

242 11R

Abstract:

A computer controlled apparatus and method for winding electro-magnetic members such as stators comprising a stator holder, motor means for rotating the stator holder, a wire dispensing cylinder, motor means for moving the dispensing means longitudinal of the member to be wound, motor means for feeding wire to the wire dispensing cylinder and means for controlling the wire feed speed of the wire feeding motor means relative to the speeds of the motors for rotating the stator holder and longitudinally moving the wire dispensing cylinder, respectively.

Appl. No.:

6/491615

Inventors:

John H. Mabie - Radford VA
Stephen P. Smith - Radford VA

Assignee:

Kollmorgen Technologies Corporation - Dallas TX

International Classification:

F16H 2520

US Classification:

74 8915

Abstract:

A compact actuator is disclosed in which the motor, gear reduction and motion control functions are performed by an integral array of components. Instead of having separate interconnected units to perform these functions, the integral array compacts these functions into a single unit, allowing a reduction in the overall length and total weight of an actuator capable of a given output stroke and force.

International Classification:

B32B 3100

US Classification:

156154

Abstract:

A method of preparing corrosion resistant neodymium-boron-iron magnets is provided. The cleaned magnet is coated with zinc phosphate which neutralizes surface effects of contaminants and rinsed with chromic acid. A relatively large surface area having numerous mechanical interlocking sites receptive to adhesives and coatings is obtained. In one embodiment a durable, corrosion-resistant coating such as amide imide or specially formulated zinc-or chromium-rich epoxy primer is applied to the zinc phosphate coated magnet. This can be bonded to a substrate using a suitable adhesive. A flexible epoxy adhesive is used for bonding motor field assemblies.
