Electric Pump System And Method

View page
US Patent:
20190003477, Jan 3, 2019
Filed:
Apr 4, 2018
Appl. No.:
15/944841
Inventors:
- Palo Alto CA, US
Eric Bellemare - Mountain View CA, US
Yufei Zhu - Sunnyvale CA, US
Benjamin Dellal - San Francisco CA, US
Diego Alberto Silva Rodriguez - Cupertino CA, US
Assignee:
Tesla, Inc. - Palo Alto CA
International Classification:
F04C 15/00
F04C 2/10
F04C 14/28
F04C 14/26
F04C 15/06
Abstract:
An electric pump system and method of operating the same involves pumping a fluid through a fluid passageway defined in a mechanical pump from a pump inlet to a hollow shaft of a motor, through the hollow shaft to an internal motor cavity defined by a housing of the motor, and through another fluid passageway defined in the motor housing and mechanical pump that leads to a pump outlet. The system and method further involve pumping the fluid through another fluid passageway defined in the mechanical pump from yet another pump inlet to the pump outlet. The temperature of fluid exiting the hollow shaft can be assessed and used by an electronic control unit (ECU) of the electric pump system to control the same. The electric pump system can be part of a cooling and lubrication system for an electric vehicle transmission, gearbox, differential or transfer case, for example.

US Patent:
20190003572, Jan 3, 2019
Filed:
Apr 4, 2018
Appl. No.:
15/944889
Inventors:
- Palo Alto CA, US
Luke Ottaway - Los Altos CA, US
Scott Michael Graves - Felton CA, US
Eric Bellemare - Mountain View CA, US
Assignee:
Tesla, Inc. - Palo Alto CA
International Classification:
F16H 57/04
Abstract:
Systems and method for cooling and lubricating power transmission systems include providing oil to an oil tube and then to a rotor shaft via the oil tube. Oil may also be provided through at least one channel defined in an end of the oil tube inserted into an annular region of the rotor shaft, through at least one channel defined in an end of the gear shaft and between the end and a shoulder of the rotor shaft and through at least one channel defined in side surface of the rotor shaft in a region of rotor shaft inserted into the gear shaft. Such systems and method can also include providing oil a fluid passageway in a bearing shim plate via an inlet tube. Oil may also be provided through a radial gap adjacent a bearing shim plate outlet and chamber defined in the bearing shim plate.

US Patent:
20190006914, Jan 3, 2019
Filed:
Apr 4, 2018
Appl. No.:
15/944990
Inventors:
- Palo Alto CA, US
Eric Bellemare - Mountain View CA, US
Alexander Hain - Frankfurt Hochst, DE
Assignee:
Tesla, Inc. - Palo Alto CA
International Classification:
H02K 9/193
H02K 1/20
Abstract:
Systems and methods for cooling power transmission systems are include providing oil through an aperture defined in a housing to a stator cooling ring, through the stator cooling ring and into stator cooling channels, through the stator cooling channels and into spaces defined between the housing and jet rings, and through holes in the jet rings and onto the end-windings. The stator cooling ring, stator cooling channels and jet rings can encircle the stator and end-windings and, via the holes in the jet rings, spray pressurized jets of oil from various angles onto the end-windings, and in particular middle regions thereof. Seals may be used between the jet rings and housing, and between the jet rings and stator ends. The seals may be compressed so as to form an interference fit between the jet rings and housing or stator ends as the case may be.

US Patent:
20180091012, Mar 29, 2018
Filed:
Nov 30, 2017
Appl. No.:
15/827435
Inventors:
- Palo Alto CA, US
Tomas Vianna Martins - San Francisco CA, US
Scott Michael Graves - Felton CA, US
Ethan Swint - Sunnyvale CA, US
Eric Bellemare - Mountain View CA, US
Lev Fedoseyev - San Jose CA, US
Benjamin Dellal - San Francisco CA, US
Leif E. Olsen - Menlo Park CA, US
Alexander Hain - Frankfurt Höchst, DE
Assignee:
Tesla, Inc. - Palo Alto CA
International Classification:
H02K 1/32
H02K 1/16
H02K 5/16
H02K 3/12
H02K 9/193
H02K 1/27
Abstract:
An electric motor includes a case, a stator that includes a stator laminaiton and end-windings, a rotor coupled to the case via at least one rotor bearing. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion. The hollow cylindrical body includes an inner wall, an outer wall, a first distal end, and a second distal end. The first shaft portions couples to the first distal end and the second shaft portion couples to the second distal end. The second shaft portion includes a fluid feed tube formed therewith having a fluid receive end and a fluid feed end, the fluid feed end extending to a central inner portion of the hollow cylindrical body. A plurality of fluid exit ports adjacent the first distal end and the second distal end of the hollow cylindrical body spray fluid onto components of the stator.

Filed:
Nov 30, 2017
Appl. No.:
15/827506
Inventors:
- Palo Alto CA, US
Tomas Vianna Martins - San Francisco CA, US
Scott Michael Graves - Felton CA, US
Ethan Swint - Sunnyvale CA, US
Eric Bellemare - Mountain View CA, US
Lev Fedoseyev - San Jose CA, US

International Classification:
H02K 9/193
H02K 9/197
H02K 1/32
H02K 5/173
H02K 7/08
Abstract:
An electric motor includes a case, a stator that includes end-windings, a rotor coupled to the case via at least one rotor bearing, at least one drive motor fluid pump, and drive motor electronics. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion, a fluid feed tube having a fluid receive end and a fluid feed end, the fluid feed end extending into the hollow cylindrical body, and a plurality of fluid exit ports. The drive motor electronics power the stator with or without causing rotation of the rotor. The drive motor fluid pump pumps fluid into the hollow cylindrical body via the fluid feed tube, pumps the fluid out of the plurality of fluid ports, and onto the stator end-windings to collect heat from the rotor and the stator. The heated fluid may be used for heating a battery.
