Abstract
A pump-motor combination includes a motor () and a pump (). The pump has a first rotor () and a first housing). The motor is an electric motor () having a second rotor (), a stator () and a second housing (). The first (pump) rotor () is at least partially coupled, and the second (motor) rotor () is completely coupled, to a common rotating shaft () in order to enable transmission of rotation of the second (motor) rotor () to the first (pump) rotor (). The pump-motor combination can be installed with the gearbox (G) or transmission of a motor vehicle, to assure supply of lubricant () when a primary lubricant pump () has not been operating, for example, upon start-up. Use of the common shaft () minimizes frictional losses during operation and reduces the cost of manufacture, since fewer bearings are needed.
