Definitions
- the invention is concerned with an electrically driven Pump with a disc rotor Electric motor.
- the object of the present invention is a to create an electrically powered pump with minimal axial length is easy to assemble.
- the task is carried out electrically driven pump of the type described solved at which is a magnetic ring of the disc rotor on the pump wheel is arranged.
- the solution according to the invention has the advantage that the integrated design of the pump impeller with the Motor rotor creates a single rotating part that in one Process can be balanced and thereby become a Contribution to cost reduction. Thanks to the integrated design is also a significant reduction in the axial length of the Unit possible, especially since no additional flange parts are required, which also further costs cause. As a further advantage of the invention electrically driven pump is the possible Weight saving to mention, especially when using is advantageous in the automotive field.
- the magnetic ring in one of fluid flow area is arranged.
- the number of parts and the assembly costs can be reduced.
- the unnecessary seal also avoids the frictional losses caused by the sealing elements for example in the case of a mechanical seal, as in a dry runner is often intended to be significant can.
- the magnetic ring of the designed as a disc rotor electric motor its possible rotationally symmetrical disc shape none Splash losses caused by conventional wet runners with the rotors of the electric motor flowing around Loss of efficiency.
- stator of the electric motor is outside of that of fluid flow area of the pump is arranged, for example outside of the pump housing or in one separate area from which the fluid flows sealed chamber, preferably also a control and / or power electronics for the electric motor in one such chamber can be arranged.
- a control and / or power electronics for the electric motor in one such chamber can be arranged.
- the electrically driven pump as Radial pump is formed with a radial wheel on the Rear of the magnetic ring is arranged.
- the insignificant Axial length of the magnetic ring leads to such Embodiment to a minimum axial length of the Radial wheel of the pump, the stator and optionally the electronics axially save space in the area anyway necessary bearing elements of the pump wheel in the already addressed chamber radially outside the storage space can find.
- the pump is preferably further provided that the Magnet ring and the adjacent housing wall as hydrodynamic plain bearing for absorbing axial forces are trained.
- this particularly simple Embodiment serves the inevitably existing magnetic gap as a plain bearing, a particularly space-saving hydrodynamic thrust bearing is created without additional parts get along during assembly.
- the shaft of the pump wheel in the housing hydrodynamic plain bearings to absorb the radial forces be stored.
- the thrust bearing it is also conceivable Magnetic bearing to absorb the axial forces in the electric motor to integrate.
- the electrically driven pump according to the invention can basically used in a wide variety of applications come and accordingly as a water pump, air conditioning compressor, Petrol pump or hydraulic oil pump can be designed, where themselves due to their short axial length and their low number of parts especially for use in Suitable for motor vehicles. Especially with water pumps So far it has been common to mechanically use the V-belt or drive a toothed belt.
- the pump according to the invention has a comparable axial length of one conventional water pump with a pulley while known electrically powered water pumps in Motor vehicle area conventional with flanged Electric motor are designed and corresponding to the input have mentioned disadvantages.
- the picture shows an electrically driven water pump 10 for use in the automotive field.
- the water pump 10 has a pump housing 12, one rotatable in the housing 12 mounted pump wheel 14, which is designed as a radial wheel, and an electric disc rotor Drive motor 16.
- the radial outlet 18 of the pump is located between the axial suction side 20 and the drive motor 16.
- it is designed as a disc rotor Electric motor 16 has a magnetic ring 22 which is immediate formed on the substantially as a radial surface Rear 24 of the pump wheel 14 is arranged. by virtue of this arrangement serves as the impeller 14 Motor rotor and forms a compact unit in one Operation can be balanced.
- the disc-like Formation of the magnetic ring 22 avoids splash losses, such as they would be created by a separate motor rotor.
- the pump works as a wet rotor and it is no shaft seal between twisted relative to each other Components necessary, the friction losses and costs would cause.
- the sealing of the entire unit will achieved only by sealing the housing 12 what is permanently possible without any problems.
- the stator 26 of the disc rotor 16 is seated in one of them flowed area sealed chamber 28 on the Back of the impeller 14 is annular.
- a Intermediate wall 30 of the pump housing 12 with a radial Extension separates the fluid area from the chamber 28.
- the chamber 28 also takes a drive and Power electronics 32 for the electric motor 16.
- the Chamber 28 extends in a ring around a storage area 34 of the housing, being between a shaft 36 of the impeller 14 and one forming the bearing area 34 of the housing 12 annular axial wall rolling or preferably plain bearings 38 are provided to absorb the radial forces.
- the magnetic ring 24 and the adjacent partition 30 in such a way formed that a hydrodynamic in the magnetic gap Plain bearing arises that the axial forces of the impeller 14th supported extensively on the intermediate wall 30 of the housing 12.
- a magnetic bearing for absorbing the axial forces is conceivable the electric motor 16 is integrated.
- an electrical driven water pump can the pump concept shown with an electric motor designed as a disc rotor too used in other pumps, for example in an air conditioning compressor, a petrol pump or an oil pump, for example for the hydraulic oil of a servo pump or at an electro-hydraulic brake.
- an electric motor designed as a disc rotor too used in other pumps, for example in an air conditioning compressor, a petrol pump or an oil pump, for example for the hydraulic oil of a servo pump or at an electro-hydraulic brake.
- the presented concept of an integrated unit Motor rotor and impeller can also be used Use turbines, the magnetic ring accordingly a suitable location of a turbine wheel and interacts with the fixed stator of a generator. In such an application, the same advantages as with an electrically driven Pump.
