Description
Technical field
The utility model relates to a kind of synchronous machine, the improvement technology of a kind of single-phase permanent synchronous machine of saying so with having.
Background technology
Existing air-conditioning draught fan is used the single-phase capacitor running asynchronous machine mostly, and single-phase capacitor running asynchronous machine cost is low, but efficient is also low.In order to raise the efficiency, the employing dc brushless motor that has, its efficient height, but cost is also high.
In addition, also have a kind of single-phase permanent synchronous machine, the number of pole-pairs of its rotor is identical with the number of pole-pairs of stator, and the interaction of rotor field and stator field makes rotor be rotated together with synchronous speed in tow by the armature rotating magnetic field.Itself does not have starting torque permagnetic synchronous motor, thereby does not have the self-starting ability.At present commonly used have this several states, and a kind of is the pawl pole permanent-magnet synchronous machine, is fit to the multipole slow-speed of revolution, small-power, inefficient occasion; Another kind is to adopt the way that does not wait air gap between stator and the rotor, and stator core salient pole tooth and rotor are at interval, and be every big on one side extremely down little on one side, makes rotor when starting, and a direction electromagnetic force is bigger than other direction, and motor rotates towards a direction.But it is influential to electric efficiency to add air gaps, and air gap changes in addition also influences rotor initial condition position, takes the motor of this method starting, and directional starting can not guarantee 100%; The third takes the asynchronous starting way, and is suitable high-power, the occasion that efficient is high, but its cost height.
Therefore to press for a kind of cost suitable with the single-phase capacitor running asynchronous machine in current market, and efficient and dc brushless motor are approaching and single-phase permanent synchronous machine with self-starting ability.
The big range of application of single-phase permanent synchronous machine is applicable in the air conditioning chamber, outdoor fan.

Embodiment
Below in conjunction with the drawings and specific embodiments self-starting single-phase permanent synchronous machine of the present utility model is described further.
Shown in accompanying drawing 1 to 9, disclosed single-phase permanent synchronous machine can be used as the air-conditioning draught fan motor in the present embodiment, it is the single-phase permanent synchronous machine that the self-starting ability is arranged, include the bearing 5 of rotating shaft 1, rotor 2, stator 3, end cap 4 and supporting revolving shaft 1, rotor 2 is sleeved in the rotating shaft 1, rotor 2 can be fixed (as shown in Figure 7) or be controlled at rotation (shown in Fig. 8,9) in the certain angle by mechanical device with axle 1, stator 3 is sleeved on the outside of rotor 2, and the rotating shaft 1 of rotor 2 is installed on the electric motor end cap 4 by bearing (5), and end cap 4 is connected and fixed with motor stator 3.As shown in Figure 2, rotor 2 is permanent magnet poles, and its N, the S utmost point distribute along circle alternate, is provided with 8 magnetic poles altogether.Shown in accompanying drawing 3,4, stator 3 is the salient pole iron core of interior dentation, has 16 salient pole core tooth 31.Coil the formation salient pole on each salient pole core tooth 31 of stator 3, the salient pole number of stator 3 is twices of rotor 2 number of magnetic poles, and promptly stator 3
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, the self-starting single-phase permanent synchronous machine that a kind of novel structure is provided, has high performance-price ratio.
The technical solution of the utility model is: a kind of self-starting single-phase permanent synchronous machine, include rotating shaft, rotor, stator, rotor is sleeved in the rotating shaft, and stator is sleeved on the outside of rotor, it is characterized in that: described rotor is a permanent magnet pole, and its N, the S utmost point are alternately distributed; Described stator is the salient pole iron core of interior dentation, coils the formation salient pole on each salient pole core tooth of stator, and the salient pole number of stator is the twice of rotor magnetic pole number.
On the odd number salient pole of described stator positive and negative company around coil be linked to be the work winding, on the stator on the even number salient pole positive and negative company around coil be linked to be the starting winding, electric capacity is in parallel with the work winding on the starting winding string, formation direction operation magnetic field.Because the work winding is to concentrate winding, shortens the winding overhang size, more saves copper cash, reduces stator copper loss; Rotor adopts permanent magnet, improves the motor efficiency, and it is suitable with AC induction motor to reach cost, and efficient obviously improves, the effect that usefulness need not be automatically controlled near dc brushless motor, and cost has greater advantages.
The salient pole core tooth at described starting winding place and the gap of rotor are less than the salient pole core tooth at work winding place and the gap of rotor, thus increase directional starting ability.
The relative revolution space that under non operating state, has certain angle between described rotor and the rotating shaft; In working order down, rotor and the motion of rotating shaft one guarantee the electric motor starting no-load condition, enter fast synchronously.
Described motor is electrically connected motor speed-changing operation with the peripheral hardware variable frequency power supply.Thereby this motor has the ability of directed changed speed operation.
Self-starting single-phase permanent synchronous machine of the present utility model, its directional starting can reach 100%, and motor enters synchronously fast, and is out-of-step free, improve the starting quality greatly, and its cost is low, efficient is high, thus a magnetic pole of two salient pole respective rotor 2 that expand.Shown in accompanying drawing 5,6, with positive and negative company on the odd number salient pole on the stator 1 around coil be linked to be work winding 6, on the stator 2 on the even number salient pole positive and negative company around coil be linked to be starting winding 7, it is in parallel with work winding 6 that starting winding 7 string is gone up electric capacity, formation direction operation magnetic field.In addition, the salient pole core tooth 71 (as Fig. 4) at starting winding 7 places is littler with rotor 2 gaps than the salient pole core tooth 61 (as Fig. 4) at work winding 6 places with rotor 2 gaps, to increase the starting capacity of orientation.
Its rotor 2 is provided with stopper slot, thereby with rotating shaft 1 revolution space (shown in Fig. 8,9) of certain angle is arranged, and is controlled at certain limit by mechanical device, starting back rotor 2 and the motion of rotating shaft 3 one, no longer include relative motion, guarantee the electric motor starting no-load condition, enter fast synchronously.When motor is electrically connected with the peripheral hardware variable frequency power supply, this motor then has the ability of directed changed speed operation.
