Publication number: 20240017602Abstract: An e-axle assembly includes a housing extending from a first housing end to a second housing end to define an internal compartment. At least one electric motor is disposed in the internal compartment and includes a stator and a rotor rotatable relative to the stator about an axis. The rotor defines a hollow extending internally within the rotor, and at least one of a gearing mechanism, a shifting actuator, and/or a differential is disposed within the hollow (and thus packaged within the rotor). In a preferred arrangement, all and any of the gearing mechanisms, shifting actuators, and differential are disposed within the hollow of the rotor. This internal packaging of the drive components within the rotor reduces an overall space and weight of the e-axle assembly relative to the prior art designs to more easily and readily achieve the smaller space and weight allotments afforded by electric and/or hybrid vehicles.Type: ApplicationFiled: July 12, 2023Publication date: January 18, 2024Inventors: Donald REMBOSKI, William Kroppe, Gary Rogers, Mark Versteyhe, John Stoiber

Patent number: 11863053Abstract: A lubricant supported electric motor includes a stator presenting an outer raceway and a rotor extending along an axis and rotatably disposed within the stator. The rotor presents an inner raceway disposed in spaced relationship with said outer raceway to define at least one hydrostatic support chamber disposed therebetween. A lubricant is disposed in the hydrostatic support chamber for supporting the rotor within the stator. A monitoring port is disposed in fluid communication with the at least one hydrostatic support chamber, and a sensor is coupled with the monitoring port for monitoring an operating characteristic of the lubricant disposed in said at least one hydrostatic support chamber. This monitored operating characteristic is then used to determine a real-time operating condition of the lubricant supported electric motor.Type: GrantFiled: October 7, 2020Date of Patent: January 2, 2024Assignee: NEAPCO INTELLECTUAL PROPERTY HOLDINGS, LLCInventors: Donald Remboski, Jacqueline Dedo, Mark Versteyhe
