Abstract
The invention provides a three-phase hybrid stepping motor which comprises a stator and a rotor, wherein, the inner hole of the stator is equipped with 9 poles, and each pole is equipped with a plurality of teeth; and the outer ring of the rotor is equipped with a circle of teeth. The three-phase hybrid stepping motor is characterized in that the intertooth included angle on each pole of the stator is less than the intertooth included angle on the rotor; and the tooth width on the rotor is less than the tooth width on the stator. The three-phase hybrid stepping motor of the invention can eliminate the harmonic wave under multiple frequency channels, thus having relatively loosened processing requirements of the stator and the rotor, and obviously reducing vibration and noise. The three-phase hybrid stepping motor can be widely applied to controlling cameras in security equipment and stage lamps, and particularly to scenes in need of low noise such as medical instruments and equipment, office automation appliances and the like.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of three-phase hybrid stepping motor.
Background technology
Three-phase hybrid stepping motor is a kind of electronic installation that electric impulse signal is converted into discontinuous mechanical movement.Because the discontinuity of its motion is easy to generate vibration and noise.The traditional minimizing vibration and the method for noise have two kinds, and it is unequal that a kind of method is that the facewidth with stator and rotor is made as, and another kind of method is to adjust the angle between each tooth on the stator poles, make the angle between itself and the rotor tooth unequal.More than two kinds of all adjustable magnetic conductance rates of change of adjusting between the rotor of method, make motor in the process of running, high order harmonic component obtains weakening, thereby reaches the purpose that reduces vibration and noise.But owing to be to adopt the fixing harmonic wave of eliminating a type, thus to the processing request of stator and rotor than higher, in the course of processing, any tiny distortion that stator and rotor produce, for example burr all can cause the effect of harmonic carcellation undesirable.
Summary of the invention
Purpose of the present invention exactly in order to address the above problem, provides a kind of new three-phase hybrid stepping motor.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of three-phase hybrid stepping motor, comprise stator and rotor, and stator inner hole is provided with nine utmost points, and each extremely is provided with a plurality of teeth, and the rotor outer ring is provided with a circle tooth; Be characterized in that each between cog angle of extremely going up of described stator is less than epitrochanterian between cog angle, the described epitrochanterian facewidth is less than the facewidth on the stator.
Each between cog angle of extremely going up of described stator is than the little 0.2-0.3 degree of epitrochanterian between cog angle, and the 0.8-0.9 that the described epitrochanterian facewidth is the facewidth on the stator doubly.
Each between cog angle of extremely going up of described stator is 6.96 degree; Described epitrochanterian between cog angle is 7.2 degree; The facewidth of described rotor is 0.84 times of the stator facewidth.
Three-phase hybrid stepping motor of the present invention all has the mode of elimination at the harmonic wave under a plurality of frequency ranges, thus relative loose to the processing request of stator and rotor, and also it is also more obvious to reduce the effect of vibration and noise.Three-phase hybrid stepping motor of the present invention can be widely used in the control of camera in the security protection equipment, and the control of stage lighting also is specially adapted to Medical Instruments and equipment, and business automation equipment etc. need the occasion of low noise.
