Compared with the motors in the prior art, the servo motor has the advantages of being accurate, diverse in output and low in vibration.
Description
Technical field
The present invention relates to a kind of servomotor, more particularly, to a kind of centrifuge servomotor.
Background technology
From the point of view of the development of centrifuge, from it is earliest when the direct current generator with carbon brush that uses, frequency conversion is used later
Slowly motor has been changed into variable-frequency motor after device control, because client more comes higher for the requirement of centrifuge, now made
It is used for centrifuge with servomotor, although cost improves, but because servomotor possesses more functions, from
Mainly having used it has the function of positioning in scheming, and horizontal rotor can be stopped at the starting of operating when centrifuge is stopped
Position, can so facilitate the crawl of mechanical hand.But still need the precision problem for solving motor.
The content of the invention
The purpose of the present invention is exactly that to provide a kind of precision for the defect for overcoming above-mentioned prior art to exist accurate, defeated
Go out diversification, shake small centrifuge servomotor.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of centrifuge servomotor, including
Motor body,
Upper lid on motor body,
The spindle nose on lid is connected to,
The screw thread spindle nose of spindle nose front end is arranged on,
The encoder of controlled motor main body.
Described upper lid is provided with the sealing draw-in groove of fixed seal ring.
Described motor body is positioned through pulse.
Described upper lid is evenly arranged with several mounting holes for installing motor body.
Described mounting hole is provided with 6.
Described thread spindle headband has the thread of M12*12 with fixed rotor.
Servomotor disclosed in the present application is positioned as other servomotors mainly by pulse, and servomotor is received
To 1 pulse, the corresponding angle of 1 pulse will be rotated, so as to realize displacement, because servomotor is in itself
Possess the function of sending pulse, so servomotor often rotates an angle, can all send the pulse of respective amount,
So, echoed with the pulse shaping that receives of servomotor, consequently, it is possible to system will know that how many pulse sent out
To servomotor, while received that how many pulse are returned again, in this way, it is possible to the rotation of motor is accurately controlled very much,
So as to realize accurate positioning, 0.001mm can be reached.We are used it on centrifuge, are mainly tested
Room high degree of automation, centrifuge carries the effect of centrifugation as the important process device in the inside one,
If being captured by mechanical arm, it is necessary to which the original position and stop position of centrifuge are fixed on into same position,
The centrifuge tube in crawl centrifuge, whole servomotor and common servomotor could be so positioned by manipulator
It is different, according to specificity on centrifuge, sealing ring draw-in groove is increased, motor shake in the running is prevented,
It is mounted with that circular flange is covered as on motor, right angle setting coordinates damper to be minimized vibrations.
Compared with prior art, the present invention has advantages below：
1st, precision is accurate：Servomotor can make control speed, and positional precision is very accurate, can turn voltage signal
Torque and rotating speed are turned to drive control object.
2nd, diversification is exported：And with characteristics such as electromechanical time constant small, the linearity is high, pickup voltages, can be
The electric signal for being received is converted into angular displacement or angular speed output on motor reel.
3rd, shake small：The servomotor increased sealing ring draw-in groove, reduce vibrations during operating.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure, lid, 4- sealings draw-in groove, 5- motor bodies, 6- encoders on 1- screw threads spindle nose, 2- spindle noses, 3-.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of centrifuge servomotor, its structure as shown in figure 1, including motor body 5, installed in motor master
Upper lid 3 on body 5, is connected to the spindle nose 2 on lid 3, is arranged on the screw thread spindle nose 1 of the front end of spindle nose 2, with
And the encoder 6 of controlled motor main body 5.
The total height of servomotor is 259mm, is right angle setting when using.Wherein screw thread spindle nose 1 carries M12*12
Thread, for the fixation of rotor, a diameter of 15mm of spindle nose 2, for and rotor engagement.The upper band of upper lid 3
There are 6 holes respectively, the installation for installing motor body 5.It is special, it is emphasized that being set on upper lid 3 to need
There is the sealing draw-in groove 4 of fixed seal ring.The rated voltage 220VDC rated power 750W volumes of servomotor
Determine rotating speed 5000rpm classes of insulation F.
Servomotor in the present embodiment is positioned as other servomotors mainly by pulse, and servomotor is received
To 1 pulse, the corresponding angle of 1 pulse will be rotated, so as to realize displacement, because servomotor is in itself
Possess the function of sending pulse, so servomotor often rotates an angle, can all send the pulse of respective amount,
So, echoed with the pulse shaping that receives of servomotor, consequently, it is possible to system will know that how many pulse sent out
To servomotor, while received that how many pulse are returned again, in this way, it is possible to the rotation of motor is accurately controlled very much,
So as to realize accurate positioning, 0.001mm can be reached.We are used it on centrifuge, are mainly tested
Room high degree of automation, centrifuge carries the effect of centrifugation as the important process device in the inside one,
If being captured by mechanical arm, it is necessary to which the original position and stop position of centrifuge are fixed on into same position,
The centrifuge tube in crawl centrifuge, whole servomotor and common servomotor could be so positioned by manipulator
It is different, according to specificity on centrifuge, sealing ring draw-in groove is increased, motor shake in the running is prevented,
It is mounted with that circular flange is covered as on motor, right angle setting coordinates damper to be minimized vibrations.
