Abstract: A hybrid oil pump for a vehicle with an engine. The hybrid oil pump includes an oil pump unit which pumps a pressurized oil to a vehicle component, a mechanical drive which drives the oil pump unit in a mechanical driving mode, an electrical drive which drives the oil pump unit in an electrical driving mode, and a freewheel clutch which automatically couples the mechanical drive with a pump shaft when a rotational speed of the mechanical drive is higher than a rotational speed of the synchronous reluctance motor. The mechanical drive is mechanically connected to and driven by the engine. The electrical drive includes a synchronous reluctance motor which is directly mechanically connected to the oil pump unit.

Abstract: An automotive electric liquid pump includes a pump wheel, an EC-motor which directly drives the pump wheel, and a cover disk. The EC-motor comprises a wet motor rotor. The wet motor rotor comprises a ring-like motor rotor cavity, and a motor rotor body comprising a cylindrical rotor body section. The cylindrical rotor body section is permanently magnetized and surrounds a motor rotor cavity which is ring-like. The cover disk is arranged at a longitudinal rotor end opposite to the pump wheel. The cover disk closes the motor rotor cavity.

Abstract: An automotive auxiliary device includes an electric drive motor which is brushless and electronically commutated. The electric drive motor includes a rotatable motor rotor which defines a longitudinal rotor axis, a motor stator, and at least one stator-sided hall-sensor. The motor rotor includes a rotor shaft, a magnet carrier, and at least one permanent magnet which generates at least two rotor poles. The permanent magnet is fixed to the magnet carrier to provide a free inner space between the rotor shaft and the permanent magnet. The permanent magnet includes an axial protruding portion which axially protrudes from at least one side of the magnet carrier. The motor stator comprises at least two stator coils which are arranged radially around the rotatable motor rotor. The hall-sensor is arranged in the free inner space and is provided as a type of radial rotor detection sensor.

Abstract: An automotive electric liquid pump includes a separation can having a radial inside which includes a static bearing ring, a pump rotor, and a motor rotor which rotates in the separation can. The motor rotor includes a radial outside having a cylindrical rotor bearing ring. The static bearing ring of the separation can corresponds to the cylindrical rotor bearing ring of the motor rotor. A first radial slide bearing is defined by the cylindrical rotor bearing ring and the static bearing ring.
