Abstract
The utility model belong to the production technology field of electric automobiles and relates to a water pump motor, in particular to a water pump motor for an electric automobile. The water pump motor is characterized in that an integrated structure of a brushless direct current motor and a water pump; a water pump outlet is arranged at the top of an outer shell of the water pump motor; a water pump inlet is arranged at a side of the water pump motor; a stator iron core is arranged at the inner periphery of the outer shell of the water pump motor; a Hall circuit board is arranged inside the bottom of the outer shell of the water pump motor to form a stator part; a rotor is arranged in a cavity of the water pump motor, and the center of the rotor is connected with the center of the bottom of the outer shell of the water pump motor by a rotating shaft; permanent magnets are arranged on the two inner sides of the rotor; and a water pump impeller is arranged on the rotor to form a rotor part. The water pump motor has the beneficial effects that the production process of the motor is simplified; the structures of an electric brush and a bearing of the traditional motor are canceled, so that the volume and the weight of the motor are effectively reduced; and with the adoption of the integrated structure of the motor and the pump body, the water circulation driven by the motor in the rotating process can conduct water cooling to the motor, so that the service life of the motor is greatly prolonged.
Description
[technical field]
The utility model relates to the electric vehicle production technical field, pump motor especially, a kind of specifically pump motor that is used for electric vehicle.
[background technique]
Electric vehicle provides car load power by battery at present, and the cooling water circulation also needs motor that power is provided, and also has influence on the life-span of electric vehicle the working life of pump motor.Usually all be the structure that adopts a driven by motor pump operation.
There is following technological deficiency in this structure:
The circulation of driven by motor water pump, motor itself is cooling not, also will note sealing problem, and water can influence the electrical machine insulation performance, and volume is bigger, occupies certain space in vehicle is arranged, and has certain weight.
In addition, the production technology of this motor is more complicated also, can't fundamentally satisfy the needs that electric vehicle is produced.
[summary of the invention]
The purpose of this utility model will solve the deficiencies in the prior art exactly, and the pump motor that a kind of volume is little, quality is little, the life-span is high is provided.
Design a kind of pump motor that is used for electric vehicle for achieving the above object, comprise electric machine casing, water pump vane, rotor, permanent magnet, rotating shaft, stator iron core, Hall circuit plate, pump motor inlet, pump motor outlet, the integral structure that it is characterized in that dc brushless motor and water pump, described pump motor cover top portion is provided with exit of pump, pump motor one side is provided with pump entrance, be provided with stator iron core around the pump motor enclosure, be provided with the Hall circuit plate in the bottom of pump motor shell, constitute stationary part; Be provided with rotor in the pump motor cavity, rotor center is connected by rotating shaft with pump motor outer casing bottom center, and both sides are provided with permanent magnet in the rotor, and rotor is provided with water pump vane, constitutes rotor portion; Rotor portion and stationary part constitute pump motor integral body.
The material of described dc brushless motor and water pump is an epoxy resin.
Described rotor top is provided with water pump vane.
The utility model is compared with prior art, simplifies on the production technology to motor: be injected into integrative-structure, cancelled the structure of the brush and the bearing of drive motor, effectively reduced the body and the weight of motor; The water cycle that motor and pump housing integral structure drive when motor is rotated can be carried out water-cooled to motor, improves electrical machinery life greatly.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, electric machine casing 2, water pump vane 3, rotor 4, permanent magnet 5, rotating shaft 6, stator iron core 7, Hall circuit plate 8 pump motors inlet 9, pump motor outlet.
[embodiment]
In conjunction with the accompanying drawings the utility model is described further, the manufacturing technology of this device is very clearly concerning this professional people.
The utility model is that motor and water pump are designed to integrative-structure, motor is a dc brushless motor, water pump vane and rotor all are epoxy resin integrated through injection molding structure, permanent magnet also wraps in the epoxy resin, stationary part also is injected into integrative-structure with the Hall circuit plate, cancel the structure of the brush and the bearing of drive motor, increased the life-span of motor greatly, effectively reduced the body and the weight of motor.When rotor rotation, with rotor be that the water pump vane of one has also driven water cycle, also cool off in the time of water cycle for motor, guarantee stability and efficient that motor works long hours.All elements all are injection-moulded in the epoxy resin, also do not need motor done other insulation processing, simplify on the production technology of motor.The utility model is installed in the electric motor car most suitable, and volume is little, quality is little, the life-span is high.
