Description
Technical field
The present invention relates to technical field of motors, particularly the synchronous decelerator of a kind of claw-pole permanent magnet.
Background technology
At present, claw-pole type permanent-magnetic synchronous is a kind of a kind of driving element be widely used in household electrical appliance, as: the driving of air conditioner wind deflector, cold and warm air heating radiator oscillating head mechanism, watch-dog The Cloud Terrace, electrically operated valve etc.The claw-pole type permanent-magnetic synchronous of usual employing single-phase ac power supply drives.
Along with the raising that progress and the people of technology realize energy-saving and environmental protection, the main motor in various household electrical appliance---single-phase ac asynchronous motor, is replaced by the brshless DC motor of efficient, energy-conservation, material-saving, environmental protection gradually, and this has become inevitable trend.This also brings a problem simultaneously, needs the device swung, originally all adopted the claw-pole type permanent-magnetic synchronous of single-phase ac power supply to drive in these electrical equipment.Nowadays use alternating current claw-pole formula permanent magnet synchronous motor again, inevitable to set up in electrical equipment two cover power-supply systems (1, ac power supply system powers to alternating current claw-pole formula permanent magnet synchronous motor; 2, DC power-supply system is powered to brshless DC motor.) cause complex structure, cost high like this.In order to simplified structure, reduce costs and use a set of DC power-supply system to be most preferred scheme.So just require a kind of New-type electric machine and occur namely not only there is the characteristic of alternating current claw-pole formula permanent magnet synchronous motor but also can run under direct current supply.
Instantly power is provided when the synchronous decelerator of claw-pole permanent magnet is useful in Medical Devices oxygenerator compressed air, the synchronous decelerator of traditional claw-pole permanent magnet is 6 to pole due to what adopt, magnet steel is ordinary ferrite magnet steel, cannot meet the requirements such as oxygenerator is large to motor torque, space is little, rotating speed operates steadily.
Utility model content
The purpose of this utility model is: for above-mentioned Problems existing, provide a kind of solution the to meet synchronous decelerator of a kind of claw-pole permanent magnet that oxygenerator is large to motor torque, space is little, rotating speed operates steadily etc. requires.
The technical solution adopted in the utility model is such: comprise motor part 1 and reduction box part 5, and described motor part 1 comprises stator 2 and rotor 3; Wherein said stator 2 and rotor 3 are respectively equipped with pole 10, and described pole 10 number is 12 right; The central authorities of described rotor 3 are installed with rotating shaft 12, rotating shaft 2) right-hand member be provided with driven wheel 11; Described driven wheel 11 is connected with the driven gear in reduction box part 5; The right side of described reduction box part 5 is provided with output revolving shaft 6, and the left end of described output revolving shaft 6 is connected with driven gear.
Further, the outer surface of preferably described rotor 3 is provided with magnet steel 4, and described magnet steel 4 is the High-performance magnetic steel that radial magnetic density is large.
Further, preferably described motor part 1 is connected with electric capacity phase splitter 7 by cable 8.
Further, the side of preferably described magnet steel 4 is provided with several installing holes 9.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: first the utility model adopts 12 to pole, after number of pole-pairs is double, rotating speed low and start time impulse current little, the corresponding reduction of torque pulsation, the reduction box part of adapted design simultaneously, well solve the problem that rotating speed operates steadily, magnet steel aspect is by changing the processing technology of magnet steel, under the condition not increasing cost, increase the radial magnetic of magnet steel close, the requirement that in meeting, moment is large, so the volume of motor also need not increase, the volume of oxygenerator also obtains reduction relatively.And adopt electric capacity phase-splitting to run, make that motor noise is little, the life-span is long, it is controlled to turn to.
