Description
Technical field
The utility model is related to a kind of servo motor magnet steel surface-mount type mistake pole rotors, belong to technical field of motors.
Background technology
With the development of modern industry, the running precision of various mechanical equipments, stationarity are required original higher.Motor
It is the main power source of mechanical equipment, how preferably to improve stationarity and accuracy is also present design of electrical motor personnel and electricity
What machine manufacturer had to face.
Utility model content
In order to improve the precision and smoothness of servo motor, the utility model provides a kind of servo motor magnet steel table
Mounted mistake pole rotor.
The technical solution of the utility model is as follows：
A kind of servo motor rotor, the rotor include rotor core, shaft, magnet steel, laminate rivet, are oriented to rivet, institute
It states in rotor core indentation shaft, the magnet steel is pasted onto by glue on rotor core, and two-stage rotor iron core is to be oriented to rivet
Wrong pole is formed after positioning and by laminating rivet closed assembly.
Preferably, 4 closed assembly rivet holes and 1 guide-localization hole are set in the punching of above-mentioned rotor core,
10 magnetic pole partitions are circumferentially uniformly arranged, the guide-localization hole is θ ° with nearest magnetic pole partition angle, two rotor cores
Carry out fastening closed assembly by 4 closed assembly rivet holes and be used for wrong pole there are other 1 guide-localization hole to position, by closed assembly it is good two
Section rotor core forms wrong pole rotor and is pressed into shaft.
Preferably, the value of above-mentioned θ is 0 18 ° of ＜ θ ＜.
Preferably, first in above-mentioned rotor core is pressed into shaft by forward direction, and second reversed and rotate
180 ° of+2 θ ° of indentation shaft, the position in two rotor cores reserved guide-localization hole when being pressed into are inserted into guiding rivet and are oriented to, formation
θ ° of wrong pole 2
Preferably, above-mentioned magnet steel is not uniform thickness.
The advantageous effect that the utility model is reached：
The utility model separates radial through iron core upper magnetic pole to be positioned, and the section formed axially through wrong pole is positioned,
To improve the installation accuracy of magnet steel, by the optimization to magnet steel mounting surface pole embrace, meeting, magnetic pole partition machinery is strong
The leakage field between magnetic pole is spent and reduces, meanwhile, what wrong pole rotor and not uniform thickness magnet steel were formed does not wait gaps, optimizes air-gap field,
Cogging torque is advantageously reduced, the stationarity of motor low speed is improved, reduces torque ripple and the fluctuation of speed under high-speed cruising, to
Motor operation control accuracy is improved, high-precision applications occasion is can be widely applied to, such as industrial robot, digital control processing, 3C industries
Deng.In addition to this, the utility model improves the operability of assembly, greatly improves working efficiency, is convenient for mass production.
