Abstract
The utility model discloses a multi-pole mixed style stepping motor. The multi-pole mixed style stepping motor comprises a rotor iron core, rotor tooth grooves, rotor teeth and a stator iron core as well as multiple magnetic poles which are arranged on the stator iron core and provided with stator teeth and stator tooth grooves, wherein twelve magnetic poles are arranged, an interelectrode included angle between two magnetic poles is 33.3 degrees, and the interelectrode included angles between other magnetic poles and adjacent magnetic poles are all 29.7 degrees; and as the quantity of the magnetic poles is increased, the response speed during mutual change of corotation and reversal directions of the rotor of the multi-pole mixed style stepping motor is promoted, and meanwhile, the output torsion is improved.
Description
Technical field
The utility model relates to a kind of electric machine, particularly relates to a kind of many magnetic poles composite stepper motor.
Background technology
Stepping motor is the open loop control assembly that electric impulse signal is changed into angular displacement or displacement of the lines.Under the situation of non-overload, the frequency and the umber of pulse of pulse signal are only depended in rotating speed of motor, the position that stops, and do not receive the influence of load variations, promptly add a pulse signal to motor, and motor then turns over a step angle.Stepping motor is imported the pulse of a control signal under charged motionless state, the logic "on" position of motor changes once, and motor will be adorned a step angle, become the single step run of stepping motor.The single step response characteristic is meant the motion process of single step run generally speaking, the relation that rotor angular displacement changed with the displacement time when being meant single step run specifically.
Composite stepper motor belongs to a type of stepping motor, general composite stepper motor, and common have 4 magnetic poles, 8 magnetic poles.8 magnetic pole composite stepper motors have high accuracy, high torque (HT), small step angle and several excellent characteristics, also have, and on step angle, have 0.9 °, 1.8 °, 3.6 °, compared with other motor, have superfine step angle.
But we hope that composite stepper motor can have tiny step angle, also can when needs change the rotor rotation direction, make response faster, compare in same frequency segment with other composite stepper motors of equal specification to have bigger torsion.
Because the defective that above-mentioned existing composite stepper motor exists, the design people actively studies innovation, in the hope of founding a kind of many magnetic poles composite stepper motor of new structure, makes it have more practicality.
The utility model content
The main purpose of the utility model is; Overcome the defective that existing composite stepper motor exists, and a kind of many magnetic poles composite stepper motor of new structure is provided, technical problem to be solved is to make it through increasing magnetic pole; Improve the response speed of rotor rotation direction; Improve the torsion of motor output, thereby be suitable for practicality more, and have the value on the industry.
The purpose of the utility model and solve its technical problem and adopt following technical scheme to realize.Many magnetic poles composite stepper motor according to the utility model proposition; Comprise rotor core, rotor teeth groove, rotor tooth and stator core and be arranged on a plurality of magnetic poles that have stator tooth and stator teeth groove on the said stator core; Said magnetic pole is 12; Wherein the interpolar angle between two magnetic poles is 33.3 °, and the interpolar angle of remaining magnetic pole and adjacent pole is 29.7 °.
Aforesaid many magnetic poles composite stepper motor, wherein, said stator tooth is 7.
Aforesaid many magnetic poles composite stepper motor, wherein, said stator teeth groove is 6.
Aforesaid many magnetic poles composite stepper motor, wherein, the facewidth of said stator tooth is 0.3mm.
By technique scheme, many magnetic poles of the utility model composite stepper motor has advantage at least:
Through increasing the quantity of magnetic pole, the rotor that has promoted many magnetic poles of the utility model composite stepper motor just changes, the response speed when reverse directions changes mutually, has improved outputting torsion simultaneously.
In sum, many magnetic poles composite stepper motor of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
