Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
The specific implementation mode of type carries out clear, complete description, it is clear that described embodiment is that the part of the utility model is real
Apply example, rather than whole embodiments, nor limitations of the present invention.Based on the embodiments of the present invention, this field
The every other embodiment that those of ordinary skill is obtained under the premise of not making the creative labor, belongs to the utility model
Protection domain.
As shown in Figure 1, Figure 2, a kind of motor for vane type direct current centrifugal blower, including outer rotor 1, radial shoe magnetic pole 2,
Stator armature iron core 3, armature winding 4, magnetic induction position sensor 5 and control circuit board 9, the radial direction shoe magnetic pole is three
Right, in the embedded outer rotor, the poles N and the poles S of the shoe magnetic pole are spaced apart, and the stator armature iron core is six teeth, and six
A armature winding is chained together by a conducting wire, in six armature winding direction of any one winding coil coiling with
The direction of its adjacent winding coil coiling is on the contrary, two winding coil coilings of arbitrary interval in six armature winding
Direction is identical, as soon as the coiling in the direction of the clock of the coil of winding, the coil of a next winding is counterclockwise
Coiling, winding coil coiling in the direction of the clock again next, i.e., the direction of the winding coil coiling at three intervals
Unanimously.Radial shoe field axis 6, stator armature iron core axis 7 and horizontal axis 8 are as shown in Figure 1.In the stator armature iron
The edge of any tooth of the heart is equipped with a magnetic induction position sensor, and the control circuit board is mounted on inside motor and electricity
Machine forms one.Rotor magnetic steel forms magnetic field in air gap, and since the shape of stator core tooth is asymmetric special form
Shape, therefore motor, when being not added with electric current, outer rotor is opposing stationary, the field axis of outer rotor and the axis of stator core tooth do not weigh
It closes, forms a fixed angle, it is exactly S pole fields to make the corresponding radial direction of Hall sensor not be N pole fields, but also
Winding both sides in core tooth are completely disposed on one side under a certain magnetic pole of outer rotor, and another side is under opposite magnetic pole.In addition, opposite
For the position of the Hall sensor on motor outer rotor and stator, rest point there are six, and every apart 60 degree.According to
The position of Hall sensor, controller add the electric current of a direction to armature winding, will generate an electricity for acting on the conductor
Magnetic force, since the both sides of same armature winding are in different magnetic field, and current direction is different, therefore by the side of electromagnetic force
To being consistent, winding coil is on stator, therefore outer rotor receives a reaction force, the i.e. external rotor center axis of electromagnetic force
A torque is formed, outer rotor is forced to be rotated around central axis.When outer rotor has rotated certain angle, tooth shaft line and under
Before one field axis overlaps, the electric current in armature winding is cut off, outer rotor is made to be acted on by inertia and rotor itself magnetic field
Continue to turn in the same direction, when going to rest point, hall signal changes, and controller adds separately to armature winding immediately again
The electric current in one direction, at this time the magnetic pole of corresponding outer rotor also changed, make outer rotor continue around central axis rotation.
Constantly change current direction in armature winding and is known as the change of current or commutation.And there is no that time of electric current referred to as dead in armature winding
Area's time is in addition, in order to control the rotating speed of motor, as long as size and the time of armature supply are flowed through in control.
The stator armature iron core is formed by one time punching molded silicon steel plate stacking, and material is DW230-35, material tool
High efficiency is generated heat the advantages that small.
As a further improvement of the above technical scheme, the material of the radial shoe magnetic pole is sintered NdFeB permanent magnet
Body, the material have magnetic field intensity height, heatproof high, and stability is good, the advantages that being not easy permanently to demagnetize.
As a further improvement of the above technical scheme, the radial shoe magnetic pole is affixed in the outer rotor inner periphery,
It is magnetized structure using surface-mount type forward direction.
