Abstract
The utility model discloses an external rotor type vehicle water pump-electric generator, comprising a ring shaped permanent magnet rotor, a ring shaped stator and a water pump. The permanent magnet rotor is installed to rotate at the external circle of the stator iron core, and the permanent magnet rotor is installed on the internal circle of the belt pulley of the water pump. The ring shaped stator installed on the housing of the water pump comprises an iron core and a winding. The ring shaped stator and the ring shaped permanent magnet rotor are arranged face to face, so as to form an external rotor type water pump-electric generator with the stator rotating at the internal circle and the rotor rotating at the external circle of the stator. The electric generator and the mechanism device of the water pump operate coaxially and are directly driven, so that the multiplexing functions of the water pump and the electric generator are implemented in a consubstantial way. The external rotor electric generator and the water pump are formed into an integration, so that the combination between the external rotor electric generator and the water pump is more simple, reasonable and compact, and the cost is lower. As the stator is directly fixed on the housing of the water pump, heat quantity generated by the stator is taken away by the circulating water of the water pump without a wind-cooled heat radiation device. Therefore, a water-cooled type high effective water pump-electric generator is formed, having the advantages of low operating temperature, reasonable, simple and compact structure and no noise.
Description
Technical field the utility model belongs to a kind of automobile water-based pump-generator multiplexer.
Background technology is present, and water pump, generator that automotive field uses are stand-alone configuration, are bringing into play function separately each other.Raising along with development and national economy, progress of science and technology and living standards of the people, performance to automobile has proposed to upgrade higher requirement, still traditional stand-alone configuration water pump and air-cooled generator that Hyundai Motor still uses make the integral arrangement structure of engine rationally compact inadequately; Along with the continuous increase of car electrics loads, make that the generator and the 12V electric power system of automobile can not adaption demands now.The applicant once in the Chinese patent " water pump-generator " of on September 6th, 2002 application (ZL02252630.7), comprise a ring-type shape stator, a ring-type shape rotor and a water pump, described ring-type shape stator is installed on the described water pump cover, described ring-type shape rotor is installed on the water pump runner, described ring-type shape stator and described ring-type shape rotor cover opposite are provided with, generator and the coaxial running of mechanical water pump device directly drive, and consubstantiality is realized water pump and generating multiplex function.During concrete enforcement, having constituted a kind of plane air gap and flow direction is axial three-phase side ring formula permanent magnetism water pump-generator and a kind of water-cooled brushless excitation water pump-generator.Above-mentioned water pump-generator is in actual production, and bigger to existing auto pump change, structure is compact not enough, and the scope of application is subjected to certain limitation.
The summary of the invention the purpose of this utility model is to provide a kind of external rotor car water pump-generator, makes the more reasonable compactness of water pump-electric generator structure, and technology is more simplified, and is easier to the repacking realization on existing auto pump basis.
For achieving the above object, the technical scheme that the utility model is taked is: this external rotor car water pump-generator, comprise a ring-type shape p-m rotor, a ring-type shape stator and a water pump, it is characterized in that described ring-type shape p-m rotor is installed in the water pump pulley on the circle by its fixed mount, described ring-type shape stator core and winding are installed on the described water pump cover, described ring-type shape stator and described ring-type shape p-m rotor constitute a kind of external-rotor-type structure, generator and the coaxial running of mechanical water pump device directly drive, and consubstantiality is realized water pump and generating multiplex function.
Above-mentioned external-rotor-type water pump-generator water collecting pump and generator are integrated, make generator and the more reasonable compactness of combining of mechanical water pump, structure is more simplified, cost is cheaper, directly be fixedly mounted on the water pump cover because of stator again, the heat that stator produces passes water pump cover, take away by water pump recirculated water, greatly reduce the working temperature of generator like this, generator need not the wind-cooling heat dissipating device.A kind of working temperature is low, the water-cooled noiselessness Efficient water pump-generator of simple and reasonable compactness thereby constitute.
Appended drawings is external-rotor-type water pump-generator Structure schematic diagram
Among the figure: 1-p-m rotor fixed mount; The 2-p-m rotor; The 3-set bolt; The 4-iron core; The 5-winding; 6-fan set bolt; The 7-belt pulley; The 8-water pump cover.
The embodiment accompanying drawing is depicted as the specific embodiment and the voltage regulator control circuit figure of the utility model external-rotor-type water pump-generator.Among this external-rotor-type water pump-generator embodiment, ring-type shape p-m rotor 2 is installed on the interior circle of water pump pulley 7 by its fixed mount 1; Ring-type shape stator is made up of iron core 4 and winding 5 thereof, is installed on the cylindrical of water pump cover 8; Described ring-type shape stator and described ring-type shape rotor 2 are provided with face-to-face, constitute a kind of stator at interior circle, and rotor is at the external-rotor-type water pump-generator of stator cylindrical rotation; Generator and the coaxial running of mechanical water pump device directly drive, and consubstantiality is realized water pump and generating multiplex function.
When 7 rotations of motor driven water pump pulley, ring-type shape p-m rotor 2 makes the stator induction produce three-phase alternating current output with belt pulley 7 rotations, is rectified into the constant voltage direct current through voltage regulator control circuit and uses for charge in batteries with electric loading.
