Description
Technical field
The utility model relates to technical field of motors, and in particular, the utility model relates to a kind of DC permanent magnet micromachine directly can using alternating current.
Background technology
DC permanent magnet micromachine can only access DC power supply and could work, and real-life power supply is all alternating current, and general common alternating current machine because of volume large, characteristic is soft, and efficiency is low and performance controllability is poor; Can use in a large number and want the simple DC permanent magnet micromachine of the little control of cube in routine work and life.
Existing solution accesses DC permanent magnet micromachine again by after AC rectification, so just must increase special rectification circuit outside motor, therefore certainly will will increase the assembly space of motor, also can affect the consistency of the outward appearance of motor and attractive in appearance.
Summary of the invention
The purpose of this utility model is the deficiency effectively overcoming above-mentioned technology, and provide a kind of DC permanent magnet micromachine directly can using alternating current, this motor directly can carry out work by incoming transport electricity, and the volume of motor and outward appearance can not change.
The technical solution of the utility model is achieved in that it comprises iron-clad, has a support in iron-clad, and the middle part of described support has circular containing cavity, and is provided with oiliness bearing in this containing cavity; A bar shaped storage tank is provided with between described support and iron-clad inwall, this bar shaped storage tank internal fixtion is provided with a rectifier, two ac input ends of described rectifier are connected to the power input of motor, and the DC output end of this rectifier is connected on the carbon of motor, and carbon is arranged in brush.
Preferably, inductance is provided with between the DC output end of described rectifier and the brush of motor.
Preferably, two DC output ends of described rectifier are provided with ground capacity.
Preferably, described support is also provided with carbon resettlement groove, the both sides be arranged at oiliness bearing of carbon resettlement groove symmetry, are provided with carbon cover in carbon resettlement groove, and are provided with carbon in carbon cover.
The beneficial effects of the utility model are: the utility model in life size motor on the special rectifier of design and installation, two ac input ends of rectifier connect two power inputs of motor, and two DC output ends after rectifier rectification connect the brush of motor; Such DC permanent magnet micromachine just can directly work by incoming transport electricity, and the volume of motor and outward appearance all can not change.
[accompanying drawing explanation]
Fig. 1 is internal structure schematic diagram of the present utility model.
[embodiment]
Below in conjunction with drawings and Examples, the utility model will be further described.
With reference to shown in Fig. 1, a kind of DC permanent magnet micromachine directly can using alternating current that the utility model discloses, concrete, it comprises bonnet 10, have in bonnet 10 and have a support 20, the middle part of described support 20 has circular containing cavity, and is provided with oiliness bearing 30 in this containing cavity; A bar shaped storage tank 40 is provided with between described support 20 and bonnet 10 inwall, this bar shaped storage tank 40 internal fixtion is provided with a rectifier 50, two ac input ends of described rectifier 50 are connected to the power input of motor, the DC output end of this rectifier 50 is connected on the carbon of motor, and carbon is arranged in brush.
Further, two DC output ends of described rectifier 50 are provided with ground capacity 502.
Further, described support 20 is also provided with carbon resettlement groove, carbon resettlement groove symmetry be arranged in the both sides of oiliness bearing 30, be provided with in carbon resettlement groove carbon cover 60, and carbon cover 60 in be provided with carbon 601.
The utility model in life size motor on the special rectifier 50 of design and installation, two ac input ends of rectifier 50 connect two power inputs of motor, and two DC output ends after rectifier rectification connect the brush of motor; Such DC permanent magnet micromachine just can directly work by incoming transport electricity, and the volume of motor and outward appearance all can not change.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, can occur various distortion and amendment, all those of ordinary skill in the art, according to describing retouching, the amendment made above or equivalent replacing, all belong to the scope that the utility model is protected.
