Description
Technical field
The utility model relates to pump motor technical field more particularly to a kind of pump motors of electric car.
Background technique
Water pump is a kind of mechanical equipment for conveying liquid or be pressurized liquid, it will be outside the mechanical energy of prime mover or other
Energy sends liquid to, increases liquid energy, is mainly used to convey liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion
With liquid metal etc., liquid, admixture of gas and the liquid containing suspended solids also can transport.The technical parameter of pump performance
There are flow, suction, lift, shaft power, water power, efficiency etc.；Volume water pump, vane pump can be divided into according to different working principles
Etc. types.Positive displacement pump is to transmit energy using the variation of its swept volume of a single chamber；Vane pump is the phase using rotary vane and water
Energy is transmitted in interaction, there is a types such as centrifugal pump, axial-flow pump and mixed-flow pump.
Pump motor is the core drive equipment of water pump, and the mass parameter of pump motor determines the performance of water pump, electronic
The pump motor of automobile is a kind of widely applied pump motor, the shortcomings of the prior art：The too big increase of volume and weight
Automobile energy consumption；Radiating efficiency is low, reduces the service life of pump motor.
Utility model content
In view of the above-mentioned deficiencies in the prior art, the utility model provides a kind of small in size, light-weight, service life length
Water pump of electric vehicle motor.
To achieve the goals above, the utility model uses following technical solution：A kind of pump motor of electric car,
Including shell, exit of pump, pump entrance, stator and rotor, the interior of shell is provided with cavity, the exit of pump setting
In cover top portion, the side of shell is arranged in the pump entrance, and surrounding inside the housing is fixedly installed in the stator, described fixed
Attached bag includes stator core and hall circuitboard, and the rotor is arranged in chamber central.
Further, the cavity is provided with first chamber and second chamber.
Further, the hall circuitboard is set to first chamber bottom.
Further, the rotor includes shaft, permanent magnet and impeller, and the impeller is fixedly installed on the top of shaft,
The permanent magnet is set to shaft two sides.
Further, the shell, stator core, pump entrance and exit of pump are integrally formed.
The beneficial effects of the utility model：Using shell, stator core, pump entrance and the integrally formed life of exit of pump
Production. art reduces manufacturing cost；Pump motor and water pump integrated design, the water circulation energy driven when rotating pump motor
Water-cooling is carried out to pump motor, greatly improves motor life；It is designed using DC Brushless Motor, Hall electricity is arranged in stator
Road plate reduces the volume and weight of pump motor, reduces energy consumption.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Appended drawing reference in figure：1, shell；2, exit of pump；3, pump entrance；4, stator；5, rotor；6, shaft；7, leaf
Wheel；8, hall circuitboard；9, first chamber；10, second chamber；11, permanent magnet.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Embodiment 1
A kind of pump motor of electric car, including shell 1, exit of pump 2, pump entrance 3, stator 4 and rotor 5, institute
It states interior of shell and is provided with cavity, shell 1 is arranged in 1 top of shell, the pump entrance 3 in the setting of exit of pump 2
Side, the stator 4 are fixed at 1 inside circumference of shell, and the stator 4 includes stator core and hall circuitboard 8, described
Rotor 5 is arranged in chamber central.
Preferably, the cavity is provided with first chamber 9 and second chamber 10；The hall circuitboard 8 is set to first
9 bottom of chamber；The rotor 5 includes shaft 6, permanent magnet 11 and impeller 7, and the impeller 7 is fixedly installed on the top of shaft 6,
The permanent magnet 11 is set to 6 two sides of shaft；The shell 1, stator core, pump entrance 2 and exit of pump 3 are integrally formed.
In use, startup power supply, forms Hall current by hall circuitboard 8, and then stator 4 generates the magnetic field of rotation,
Rotor 5 starts turning, and the impeller 7 being fixedly connected at the top of rotor 5 follows rotation, and water flows into second chamber from pump entrance 3, then
It is flowed out from exit of pump 2, can control the velocity of rotation of rotor by hall circuitboard 8.
The utility model is easy to use as can be seen from the above embodiments, small in volume, can reduce energy consumption, improves
Heat dissipation, prolongs the service life.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
It is all simply to modify or convert using made by the utility model description, it is relevant to be applied directly or indirectly in other
Technical field is also included in the patent protection scope of the utility model.
