Description
Technical field
This utility model relates to machine field, particularly relates to a kind of novel series excited machine for small household appliances.
Background technology
The stator of single phase series motor (series excited machine) is by salient pole is unshakable in one's determination and Exciting Windings for Transverse Differential Protection forms, and rotor is made up of non-salient pole iron core, armature winding, diverter and rotating shaft etc., forms series loop by brush and diverter between Exciting Windings for Transverse Differential Protection and armature winding.
The salient pole iron core of existing series excited machine typically uses arc, surrounds rotor, and the polar arc number of degrees ratio of salient pole iron core is generally less than equal to 0.5, and magnetic field range is narrow, limits the lifting of power of motor.In addition, existing series excited machine can be divided into 54,70/76,88,95 series according to the external diameter of stator and power, and (54 series i.e. stator outer diameter is 54mm, by that analogy), external diameter size is proportional with watt level, if the power bracket of 54 serial motors is 150 ~ 250W, power bracket 300W of 70/76 serial motors ~ 500W.Wherein 54 serial motors are little due to volume, are usually used in small household appliances, such as hand-held mixer etc..But the trend of motor technology development is that volume is little, power big, and the power of 54 serial motors is little, gradually can not meet use requirement, and the volume of 70 serial motors is too big, is not suitable for small household appliances.Accordingly, it would be desirable to develop a kind of novel motor, and all meet requirement on power on volume.
Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is to provide a kind of novel series excited machine for small household appliances, and volume is little, and power is big, meets the use requirement of small size household electrical appliance.
This utility model be the technical scheme is that
A kind of novel series excited machine for small household appliances, including stator, rotor, described stator includes that the salient pole of two relative arcs is unshakable in one's determination, and described rotor is arranged between two salient pole iron cores, and the polar arc number of degrees ratio of described salient pole iron core is 0.67.
As the further improvement of technique scheme, the outside dimension of described stator is 57mm-59mm, the outside dimension of rotor be the outside dimension ratio of 31mm-32mm, rotor and stator be 0.54.The increase of stator outer diameter size is conducive to increasing power, and increases by a small margin and will not influence too much the volume of motor, makes motor still be applicable to the use requirement of small size household electrical appliance.
The beneficial effects of the utility model are:
The polar arc number of degrees ratio of the salient pole iron core of above-mentioned novel series excited machine reaches 0.67, is greatly increased effective magnetic field scope, thus increases power.Compared with 54 traditional serial motors, novel series excited machine of the present utility model is in the case of volume is close, and power can reach 250W ~ 450W, considerably increases power, has adapted to the use requirement of most of small size household electrical appliance.

Detailed description of the invention
As shown in Figures 1 to 4, a kind of novel series excited machine for small household appliances that this utility model provides, including stator 1, rotor 3.Described stator 1 includes salient pole unshakable in one's determination 2 and Exciting Windings for Transverse Differential Protection, and described rotor 3 includes non-salient pole iron core, armature winding, diverter and rotating shaft 4.Wherein two salient pole iron cores 2 of stator 1 are set to arc towards the one side of rotor 3, and its polar arc number of degrees ratio is 0.67.Two salient pole iron cores 2 are oppositely arranged.Rotor 3 is arranged between two salient pole iron cores 2, and rotates in the magnetic field between two salient pole iron cores 2.
Further, the outside dimension of described stator 1 is 57mm-59mm, preferably 58mm；The outside dimension of rotor 3 is 31mm-32mm, preferably 31.6mm；The outside dimension ratio of rotor 3 and stator 1 is 0.54.The increase of stator 1 outside dimension is conducive to increasing power, and increases by a small margin and will not influence too much the volume of motor, makes motor still be applicable to the use requirement of small size household electrical appliance.
The polar arc number of degrees ratio of the salient pole iron core 2 of novel series excited machine of the present utility model reaches 0.67, is greatly increased effective magnetic field scope, thus increases power.Compared with 54 traditional serial motors, novel series excited machine of the present utility model is in the case of volume is close, and power can reach 250W ~ 450W, considerably increases power, has adapted to the use requirement of most of small size household electrical appliance.
Above concrete structure and sized data are to be illustrated preferred embodiment of the present utility model, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art it may also be made that all equivalent variations or replacement on the premise of this utility model spirit, and deformation or the replacement of these equivalents are all contained in the application claim limited range.
