Description
Technical field
The utility model relates to a kind of electric machine, particularly relates to the little composite stepper motor of a kind of step angle error.
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.
In the design of traditional stepping motor; The precision of motor step elongation is very responsive to the accuracy of manufacture of each part of formation motor; Like rotor size, stator dimensions, rotor table magnetic and coil inductance or the like, so when producing, very high to the requirement of each size for connection precision; When causing that when the element precision deficiency motor step elongation precision is not enough, cause problems such as noise is bigger than normal, output wheel shake easily.
Because the defective that above-mentioned existing stepping motor exists, the design people actively studies innovation, in the hope of founding a kind of little composite stepper motor of step angle error of new structure, makes it have more practicality.
The utility model content
The main purpose of the utility model is, overcomes the defective that existing stepping motor exists, and a kind of composite stepper motor of new structure is provided; Technical problem to be solved is to make its facewidth that clearly defines crucial stator tooth and the ratio of groove width; And define the facewidth of crucial rotor tooth and the ratio of groove width, and improved the precision of critical piece, make that the noise of the utility model is little; 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.A kind of composite stepper motor according to the utility model proposition; Comprise stator core and rotor core; Said stator core is provided with stator tooth; Said rotor core is provided with rotor tooth, and the width ratio of the facewidth of said stator tooth and the teeth groove of said stator tooth is 0.645～0.712, and the width ratio of the facewidth of said rotor tooth and the teeth groove of rotor tooth is 0.22～0.23.
Aforesaid composite stepper motor, wherein, the facewidth of said stator tooth is 0.40mm～0.42mm, the tooth depth of said stator tooth is 0.41mm～0.42mm.
Aforesaid composite stepper motor, wherein, the facewidth of said rotor tooth is 0.42mm～0.44 mm, the teeth groove of said rotor tooth is 1.9mm～2.0mm.
By technique scheme, the utility model composite stepper motor has advantage at least:
The facewidth of the stator tooth of clearly definition key and the ratio of groove width; And the facewidth of the rotor tooth of definition key and the ratio of groove width; Be convenient to its part is processed and controlled the quality of part, improved the precision of critical piece, reduced the noise of the utility model product.
