Bearing Protection For Inverter-Driven Motor

View page
US Patent:
20070201995, Aug 30, 2007
Filed:
Feb 24, 2006
Appl. No.:
11/361329
Inventors:
Michael Harstad - Westby WI, US
Joel Duga - Onalaska WI, US
Gregory Fiegen - La Crescent MN, US
Brian Sullivan - La Crosse WI, US
James Kwiatkowski - Stoddard WI, US
Peter Kotlarek - Onalaska WI, US
Richard Heiden - Holmen WI, US
International Classification:
F04B 17/00
US Classification:
417423120
Abstract:
A refrigerant motor/compressor employs both a serviceable shaft-grounding device and a ceramic coating to protect a rolling element bearing that could otherwise be damaged by high frequency induced common mode voltage and current originating from an inverter that includes a plurality of IGBTs (insulate gate bipolar transistors). The shaft-grounding device includes a stranded copper wire brush that rides against an axial end of the shaft and a high frequency stranded grounding wire that conducts the induced current away from the shaft. The shaft-grounding device is sized and positioned so that it can be momentarily removed for inspection without having to evacuate the refrigerant. The ceramic coating provides an electrical insulating surface on a bearing bracket and other parts that support the bearing. The coating comprises titanium dioxide and aluminum oxide to provide a surface that is sufficiently hard and tough to resist damage during assembly, thereby maintaining the coating's integrity.

Anti-Reverse Rotation Valve For Scroll Compressor

View page
US Patent:
56832362, Nov 4, 1997
Filed:
Mar 21, 1996
Appl. No.:
8/619316
Inventors:
Mark W. Harrison - Onalaska WI
Peter A. Kotlarek - Onalaska WI
Charles A. Singletary - Whitehouse TX
John Kenneth Wollitz - Tyler TX
Assignee:
Alliance Compressors - Tyler TX
International Classification:
F04C 1804
F04C 2900
F04C 2902
F16K 1502
US Classification:
418 551
Abstract:
A scroll-type refrigeration compressor has a gas-liquid mixture discharge passage extending through the driver scroll drive shaft for discharging refrigerant gas and entrained lubricant into a high pressure chamber in the compressor housing. An anti-reverse rotation valve is connected to the distal end of the drive shaft and includes a valve housing with radially extending discharge ports and a closure member movable to prevent reverse flow of high pressure gas to the scroll compression chambers to prevent reverse rotation on compressor shutdown. A pressure equalization port may be formed in the valve closure member, valve housing or the distal end of the drive shaft to allow slow bleed down of pressure from the high pressure side to the low pressure side to minimize starting torque of the drive motor. The valve may be formed from a tubular metal housing and having a plug-type closure member slidably disposed therein with the housing being press fitted in a counterbore in the end of the shaft. A gas-liquid separation baffle may be disposed around the valve housing for assisting in gas-liquid separation after the mixture is discharged from the valve housing.

Scroll Apparatus With Enhanced Lubricant Flow

View page
US Patent:
52129640, May 25, 1993
Filed:
Oct 7, 1992
Appl. No.:
7/958436
Inventors:
Robert E. Utter - Onalaska WI
Daniel R. Crum - La Crosse WI
Peter A. Kotlarek - La Crosse WI
Assignee:
American Standard Inc. - New York NY
International Classification:
F04C 1804
F04C 2902
US Classification:
62498
Abstract:
In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes to produce a relative orbital motion, a means for enhancing lubricant flow through the scroll wraps. One or more passages are provided in one or both of the scroll end plates, each passage disposed to discharge lubricant between the scroll end plates, discharging adjacent the outer end of the scroll wraps immediately before the point where the scroll wraps form the first compression chamber to provide lubricant to the entire scroll wrap length. Lubricant is provided to the passages by a combination of pickup tubes affixed to the scroll end plates and inlet openings in the scroll end plates. The inlet openings accept lubricant discharged from the bearings in the apparatus. The pickup tubes rotate with the scroll end plates and remove lubricant from a sump adjacent the scroll end plates.

Scroll Compressor Reverse Phase And High Discharge Temperature Protection

View page
US Patent:
52901548, Mar 1, 1994
Filed:
Dec 23, 1992
Appl. No.:
7/995728
Inventors:
Peter A. Kotlarek - Onalaska WI
Jerry A. Rood - Onalaska WI
Bill P. Simmons - La Crosse WI
Assignee:
American Standard Inc. - New York NY
International Classification:
F04B 4708
US Classification:
417272
Abstract:
A low side scroll compressor is protected from both the potentially damaging effects of improper electrical hookup and the development of high discharge temperatures by apparatus disposed in a passage which communicates between the suction pressure portion and a discharge pressure portion of the compressor. The apparatus operates to permit gas flow from the suction to the discharge pressure portion of the compressor through a protective passage, such as when the compressor runs backwards due to miswiring, so as to avert damage to the scroll members. The apparatus permits the flow of gas from the discharge to the suction pressure portion of the compressor through the passage when the temperature of the discharge gas produced by the compressor exceeds a predetermined temperature indicative of an abnormal compressor operating condition. The resulting gas flow in the latter case causes the compressor motor to de-energize.

Reverse Phase And High Discharge Temperature Protection In A Scroll Compressor

View page
US Patent:
54529891, Sep 26, 1995
Filed:
Apr 15, 1994
Appl. No.:
8/227927
Inventors:
Jerry A. Rood - Onalaska WI
Peter A. Kotlarek - Onalaska WI
Assignee:
American Standard Inc. - Piscataway NJ
International Classification:
F04B 4900
US Classification:
417 29
Abstract:
Protective apparatus in a scroll compressor, in the form of a valve assembly, is operative to prevent compressor damage from reverse direction rotation of the scroll compression mechanism or the development of abnormally high discharge gas temperatures. The valve assembly is disposed in a passage communicating between the suction and discharge pressure portions of the compressor shell and houses a discharge temperature sensor immediately adjacent the location from which discharge gas issues from the compression mechanism. The location of the sensor and its exposure to discharge gas permits the timely sensing of abnormally high discharge temperatures and the shutdown of the compressor upon their occurrence. The valve assembly includes a vent valve which lifts, upon the reverse direction orbital motion of the orbiting scroll member and creation of a pressure less than suction pressure in the discharge pressure portion of the compressor, so as to provide an internal flow path and volume within the compressor against which the compression mechanism can pump where it would otherwise be damaged in pumping against a closed volume.
