Specific embodiment
Referring to figures 1-4, the utility model is a kind of single-phase asynchronous motor for starting synchronous operation, includes stator module
And rotor assembly, stator module are made of stator punching 1, around equipped with main phase winding 6 and secondary phase on the stator tooth of stator punching
Winding 5, the rotor core structure 4 for the squirrel-cage that rotor assembly is made of rotor punching, the stator punching one of them
Or excitation winding 2 is wound on multiple stator tooths 7, a preferably stator tooth in the present embodiment；The excircle of rotor core structure
Upper fitting is provided with the circular ferrite magnet 3 not magnetized.
Further, if circular ferrite magnet described in the present embodiment is set as along the axial direction of rotor core structure
Dry segment and be coaxial annular arrangement.
Further, it was used between circular ferrite magnet after rotor core structure cast aluminium described in the present embodiment
Cooperation of being full of is attached.
Further, width is consistent and should the stator tooth of coiling excitation winding everywhere on stator punching in the present embodiment
Stator tooth front end is arranged to trapezoidal shape structure.
According to the stator punching, rotor punching and circular ferrite magnet designed in the utility model, stator pack is carried out
Part production and rotor assembly production.The winding of stator module is additionally rushed in stator other than conventional main phase winding, secondary phase winding
It is increased on one of stator tooth of piece to the excitation winding of the circular ferrite magnet " magnetizing " on rotor core structure surface,
Excitation winding is placed in above a stator tooth on stator.Match after rotor core structure cast aluminium with circular ferrite magnet interference
Connection is closed, prevents from falling off in operational process.
After the motor normal ON power supply of the utility model, the winding of stator module, which is powered, generates rotating excitation field, squirrel-cage
Rotor core structure generate induced current drive rotor rotate；Control switch is connected at this time, is powered and is produced in excitation winding
Raw magnetic field of magnetizing reaches synchronous rotational speed to revolving speed so that the circular ferrite magnet to rotor core structure surface magnetizes
Control switch is disconnected later, and such motor enters synchronous operation state and rotates；After disconnecting power supply, due to rotor core knot
The magnetism on structure surface is not up to steady magnetic degree, and magnetism slowly automatic can eliminate, before Power resumption without magnetic state；In this way, such
Type motor just realizes the operating mode of asynchronous starting in cycles, synchronous operation.
Attached drawing 4 be in this programme motor reach asynchronous starting, synchronous operation operating mode simple circuit signal
Figure.
In the present embodiment excessive disclosure is not done for some specific structures of the motor of asynchronous starting synchronous operation, is only pair
The improvement part of this conventional monophase machine is disclosed, and is because the motor others structure position of this programme belongs to often
The prior art for advising setting does not constitute influence to the clear and integrality of this programme.
