Description
technical field:
The utility model relates to technical field of motors, more specifically to brshless DC motor used on a kind of air purifier.
background technology:
The motor of existing air purifier used for impeller all adopts AC induction motor, and its motor rotates by decelerator impeller.Its weak point is: 1, motor volume is large, and energy index is low, and speed adjusting performance is poor, has adopted decelerator simultaneously.2, its motor component volume is large, and transportation and installation are all very inconvenient.3, because needs adopt decelerator, so its production cost is higher.4, its magnet steel quantity is general adopts 8, and during low cruise, motor moves inadequate balance, has jitter phenomenon.
utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provide air purifier brshless DC motor, it has dwindled the volume of air purifier motor part greatly, reduced the production cost of air purifier motor, 12 magnet steel are housed, more steady during air purifier motor low cruise.
Technology solution of the present utility model is as follows:
Air purifier brshless DC motor, comprise dead axle and stator, stator sleeve is contained on dead axle, stator coil is installed on stator, rotor is comprised of main casing, upper shell, lower house, rotor lasso, magnet steel, upper bearing (metal) and the lower bearing of column casing shape, and upper shell and lower house are fastened on respectively on the upper and lower end face of main casing and are fixed together by king-bolt;
Moulding annular groove on the inwall of main casing, forms hat brim on the outer wall of main casing, and rotor lasso sleeve is in annular groove, and the lower end of rotor lasso is pressed on lower house, and the upper end of rotor lasso is pressed on the top margin of annular groove, and magnet steel is fixed on the inwall of rotor lasso;
Upper shell is fixed on the outer ring of upper bearing (metal), and the inner ring of upper bearing (metal) is fixed on dead axle, and lower house is fixed on the outer ring of lower bearing, and the inner ring of lower bearing is fixed on dead axle; Draught fan impeller is fixed on hat brim by stove bolt.
Described dead axle is fixed on dead axle seat.
Described 12 magnet steel circular array centered by the center of circle of rotor lasso is distributed on the inwall of rotor lasso.
Described dead axle and dead axle seat are spirally connected and are fixed together, and form motor location fixed disk on dead axle seat.
The beneficial effects of the utility model are:
1,, owing to not adopting decelerator, so it has dwindled the volume of air purifier motor part greatly, reduced the production cost of air purifier motor.
2, rotor portion is equipped with 12 magnet steel, more steady during air purifier motor low cruise.
3, its electromagnetic noise is low, and power density is high, and energy index is good, and electric efficiency is high, and moment of inertia is large.
4,, due to its small volume, transport and install more convenient.
5, its motor does not have carbon brush, adopts induction less brush-less design, and rotor is without having the connection on conductor with the external world.In running, the rotating speed of brushless electric machine is to lean on the frequency of alternating current to determine, so the higher brushless electric machine of frequency can turn sooner.
