utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and ceiling fan DC brushless motor is provided, it has dwindled the volume of ceiling-fan motor part greatly, has reduced the production cost of ceiling-fan motor, 12 magnet steel are housed, more steady during ceiling-fan motor low cruise.
Technology solution of the present utility model is as follows:
Ceiling fan DC brushless motor, comprise dead axle and stator, stator sleeve is contained on dead axle, stator coil is arranged on stator, rotor is comprised of upper shell, lower house, rotor lasso, magnet steel, rotor post, upper bearing (metal) and lower bearing, and upper shell and lower house snap together, and the upper end of rotor post is supported on the inwall of upper shell, the lower end of rotor post is supported on the inwall of lower house, together with upper shell, lower house are bolted on rotor post;
Magnet steel is fixed on rotor lasso, forms short slot on rotor post, and short slot is with under shed, and rotor lasso is placed in short slot, and rotor lasso is clamped between the top margin and lower house of short slot;
Hinged by upper bearing (metal) between upper shell and dead axle, hinged by lower bearing between lower house and dead axle.
Described 12 magnet steel circular array centered by the center of circle of rotor lasso is distributed on the inwall of rotor lasso.
On described dead axle, form draw-in groove, upper back-up ring is fastened in draw-in groove, and the inner ring of upper bearing (metal) is pressed on back-up ring, together with the outer ring of upper bearing (metal) is welded and fixed with upper shell; On dead axle, form lower bayonet slot, lower back-up ring is fastened in lower bayonet slot, and the inner ring of lower bearing is pressed on lower back-up ring, together with the outer ring of lower bearing is welded and fixed with lower house.
The beneficial effects of the utility model are:
1,, owing to not adopting decelerator, so it has dwindled the volume of ceiling-fan motor part greatly, reduced the production cost of ceiling-fan motor.
2, rotor portion is equipped with 12 magnet steel, more steady during ceiling-fan 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.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place in Fig. 1;
Fig. 3 is the annexation schematic diagram of rotor lasso and magnet steel.
In figure: 1, dead axle; 1a, upper draw-in groove; 1b, lower bayonet slot; 2, stator; 3, rotor; 31, upper shell; 32, lower house; 33, rotor lasso; 34, magnet steel; 35, rotor post; 351, short slot; 36, upper bearing (metal); 37, lower bearing; 4, upper back-up ring; 5, lower back-up ring; 6, stator coil.
embodiment:
Embodiment: see shown in Fig. 1 to 3, ceiling fan DC brushless motor, comprise dead axle 1 and stator 2, stator 2 is sleeved on dead axle 1, stator coil 6 is arranged on stator 2, rotor 3 is comprised of upper shell 31, lower house 32, rotor lasso 33, magnet steel 34, rotor post 35, upper bearing (metal) 36 and lower bearing 37, upper shell 31 and lower house 32 snap together, the upper end of rotor post 35 is supported on the inwall of upper shell 31, the lower end of rotor post 35 is supported on the inwall of lower house 32, together with upper shell 31, lower house 32 are bolted on rotor post 35;
Magnet steel 34 is fixed on rotor lasso 33, forms short slot 351 on rotor post 35, and short slot 351 is with under shed, and rotor lasso 33 is placed in short slot 351, and rotor lasso 33 is clamped between the top margin and lower house 31 of short slot 351;
Hinged by upper bearing (metal) 36 between upper shell 31 and dead axle 1, hinged by lower bearing 37 between lower house 32 and dead axle 1.
Described 12 magnet steel 34 circular array centered by the center of circle of rotor lasso 33 is distributed on the inwall of rotor lasso 33.
