US Patent:

20130111679, May 9, 2013

Filed:

Nov 4, 2011

Appl. No.:

13/289429

Inventors:

Joseph Engle - Hartville OH, US
David Molnar - Hudson OH, US

Assignee:

IMPERIAL ELECTRIC COMPANY - Akron OH

International Classification:

A47L 11/02
F16J 1/16

US Classification:

15 98, 403150

Abstract:

The present invention is a floor machine pivot joint. The pivot joint utilizes pivot pegs attached to the base of the floor machine which extend from the base into cavities formed in the sides of the yoke which, in preferred embodiments, have either partially spherical or cylindrical shape. The pivot pegs allow the yoke to pivot in substantially one plane with reduced unwanted movement of the yoke and base relative to each other.

Appl. No.:

9/255921

Inventors:

David T. Molnar - Cuyahoga Falls OH
Robert K. Hollenbeck - Fort Wayne IN

Assignee:

General Electric Company - Schenectady NY

International Classification:

H02K 1500

US Classification:

29596

Abstract:

A dynamoelectric machine has a stator end cap mounted on a stator core, which attaches a control circuit board directly onto the stator. The end cap has integrally formed fingers which permit snap on connection of the circuit board. Guide pins make certain the circuit board is oriented properly upon connection to the end cap. The end cap also has wire fixtures which hold winding leads of a winding and permit insulation displacement terminals on the circuit board to plug into the winding leads and achieve electrical contact at the same time the circuit board is mounted on the end cap. Hall devices mounted onto the circuit board are guided into pockets formed on teeth of the stator end cap for precise location. The end cap is constructed to shield the winding from contact with the motor shell. In addition, backward curved fans are employed to reduce mechanical noise in the direction of high speed rotation.
