Abstract
The utility model discloses a kind of stator punchings of small-sized wide-angle composite stepper motor for reducing harmonic wave, including punching ontology, the punching to be set inside the body eight magnetic poles, and two teeth are symmetrically arranged on each magnetic pole.The stator punching of the small-sized wide-angle composite stepper motor of the reduction harmonic wave, increase the angle on single magnetic pole between two teeth by setting, making the stator punching being applied to, small-sized composite stepper motor time-harmonic wave is smaller, and added losses are smaller, and electric current conversion ratio is higher.
Description
Technical field
The utility model belongs to step motor stator punching technical field, and in particular to a kind of small-sized big angle for reducing harmonic wave
Spend the stator punching of composite stepper motor.
Background technique
Stator punching is also referred to as stator vane, is stamped to form by the silicon steel sheet of 0.35mm or 0.5mm as different size punching
Piece be suitble to different capacity motor stator use, and existing motor stator punching often have when in use it is biggish humorous
Wave, for the motor of rotation, harmonic current or harmonic voltage can generate additional in stator winding, rotor loop and iron core
Loss, causes the integral energy transfer efficiency of motor to reduce；Harmonic current can be such that the copper loss of motor increases, so motor is serious
Harmonic load under will generate hot-spot, vibration and noise increase, temperature rise increases, cause insulating layer aging to accelerate, reduce
The service life of equipment.
Utility model content
The purpose of this utility model is to provide a kind of stators of small-sized wide-angle composite stepper motor for reducing harmonic wave
Punching, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of small-sized wide-angle reducing harmonic wave is mixed
The stator punching of box-like stepper motor, including punching ontology, the punching are set inside the body eight magnetic poles, and each magnetic pole
On be symmetrically arranged with two teeth, the angle D on single magnetic pole between two teeth be 21.5-23.5 °, the quadrangle of punching ontology is all provided with
There is aperture, aperture not only has positioning action, can also increase heat dissipation and reduce rapidoprint.
Preferably, the side length A of the punching ontology is 22-39mm.
Preferably, the length ratio of the distance between the distance B of the raker tooth of adjacent pole and two teeth on single magnetic pole C exist
Between 0.25-0.35.
The technical effect and advantage of the utility model: the stator of the small-sized wide-angle composite stepper motor of the reduction harmonic wave
Punching increases the angle on single magnetic pole between two teeth by setting, the stator punching is made to be applied to small-sized hybrid step
Smaller into motor time-harmonic wave, added losses are smaller, and electric current conversion ratio is higher.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 punching ontology, 2 magnetic poles, 3 teeth.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model

Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of determining for the small-sized wide-angle composite stepper motor of reduction harmonic wave as shown in Figure 1
The inside of sub- punching, including punching ontology 1, the punching ontology 1 is equipped with eight magnetic poles 2, and is symmetrically arranged with two on each magnetic pole 2
A tooth 3, the angle D on single magnetic pole 2 between two teeth 3 are 21.5-23.5 °.
Specifically, the side length A of the punching ontology 1 is 22-39mm.
Specifically, the length ratio of the distance between the distance B of the raker tooth 3 of adjacent pole 2 and two teeth 3 on single magnetic pole 2 C
Between 0.25-0.35.
Increase the angle on single magnetic pole between two teeth by setting, make the stator punching be applied to it is small-sized hybrid
Stepper motor time-harmonic wave is smaller, and added losses are smaller, and electric current conversion ratio is higher.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
