Abstract
The utility model discloses a stator for brushless motors, wherein, wire chases for accommodating coils are formed on the stator; each wire chase is arc-shaped; and a protrusion is formed between the two adjacent wire chases. The stator for the brushless motors has the characteristic that the output efficiency of an electric motor can be led to be high, and can be widely used as the stator for various brushless motors.
Description
Technical field
The utility model relates to a kind of cleaner, particularly relates to a kind of cleaner of the place that is used to polish.
Background technology
Brushless electric machine is because of it has brushless, low disturbs, advantages such as running is smooth and easy, low noise, the life-span is long, maintenance cost is low are widely used.The rotor of brushless electric machine is a permanent magnetic steel, link to each other with output shaft together with shell, stator is a winding coil, around winding coil, form one around full magnetic field of changeing, how much axle center of motor, the epitrochanterian permanent magnetic steel of this field drives rotates, motor has just been turned over, and therefore, motor properties is relevant with factors such as magnet steel quantity, magnet steel magnetic flux density, motor input voltage sizes.The wire casing that the stator of existing brushless electric machine holds coil is straight type, and diastema is many, and coil stationary built on the sand, it is bigger to produce noise in the operation process, and, because of diastema many, it is low to form electromagnetic field efficient, causes magnetic flux density low, thereby causes the motor delivery efficiency low.In addition, the cross section on the surface that the stator of brushless electric machine and rotor are close be shaped as arc, very nearly the same from the distance of rotor everywhere, be unfavorable for producing big moment of torsion, thereby also cause the delivery efficiency of motor low.
The utility model content
It can be the high brushless motor stator of motor delivery efficiency that technical problem to be solved in the utility model is to provide a kind of.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of stator that is used for brushless electric machine, on stator, be provided with the wire casing that holds coil, and described wire casing is an arc, is provided with projection between two adjacent wire casings.
As improvement of the technical scheme, being shaped as of cross section on the surface that is close with rotor is with stair-stepping arc.
Another improvement as technique scheme is provided with the mounting groove that is used for installing Hall element in the exit of described wire casing.
The beneficial effects of the utility model are: because the wire casing that holds coil of the present utility model is an arc, and two be provided with projection between the adjacent wire casing, diastema is few like this, forming electromagnetic field efficient improves greatly, the trapped flux amount increases greatly, thereby the delivery efficiency of motor increases greatly, can bring up to about 75% from original 50%; The shape of the cross section on the surface that will be close is made and is with stair-stepping arc in addition, and the stator inner surface each point strengthens to the range difference of rotor surface like this, produces the moment of torsion increasing, thereby also can improve the delivery efficiency of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A portion enlarged drawing among Fig. 1;
Fig. 3 is a B portion enlarged drawing among Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, a kind of stator that is used for brushless electric machine is provided with the wire casing 1 that holds coil on stator, wire casing 1 be shaped as arc, between two adjacent wire casings, be provided with projection 2, arc wire casing and projection make coil press close to wire casing more, diastema is few, has improved the efficient that forms electromagnetic field.
With reference to Fig. 2, the shape on the surface 3 that will be close with rotor becomes is with stair-stepping arc, helps the formation of moment of torsion.
With reference to Fig. 3, be provided with mounting groove 5 at outlet 4 places of wire casing 1, be used for installing Hall element, quick and easy for installation like this, help enhancing productivity.
More than though execution mode of the present utility model has been described in conjunction with the accompanying drawings, those skilled in the art can make various distortion or modification within the scope of the appended claims.
