Description
Technical field
The utility model relates to a kind of digital control servo-drive technology, a kind of specifically servomotor precision drive drive unit.
Background technology
Along with the application of microprocessor, new digital signal processor (DSP), numerical control system occurred in recent years, control section can be undertaken by software fully.The servo-drive technology has had outstanding development, the famous electric manufacturer in various countries release one after another separately servomotor and servo-driver, and constantly improve and upgrade.Servo system has become the main developing direction of contemporary high-performance numerical control, the commercialization of existing countries in the world servo system adopts is that the sinusoidal wave motor servo of digital control drives.The U/V/W three-phase electricity of servo-driver control forms electromagnetic field, rotor rotates under the effect in this magnetic field, servo in the normal speed scope, its torque is very stable, the position sensor feedback signal that the while motor carries is given driver, and driver compares according to value of feedback and desired value, and has or not step-out according to its feedback signal judgement, thereby replenish, adjust the angle of rotor rotation.
The current servo Driving technique uses the scale on automatic industrial manufacturing line increasing, the numerical control device major part all adopts the servo-drive technology, its power trend maximizes, and for obtaining suitable rotating speed and torque, adopts motor to add the mode of deceleration or speeder usually.Therefore the servo reductor of using, perhaps booster engine are arranged.But the deceleration or the speeder of machinery are because reasons such as manufacturing and heating exist the gap and the mechanical deformation of transmission.Therefore cause accurate closed loop servo control to become open loop control, and strengthen with driving-chain, even might be out of control fully because of the driving-chain fault.Therefore the existing digital control servo-drive that feedback element is installed in actuator's input does not satisfy existing mechanism SERVO CONTROL moment, speed, precision and the requirement that reduces cost.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the weak point of above-mentioned background technology, a kind of servomotor precision drive drive unit to be provided, can accurately realizing the requirement of control command, eliminate the error in the driving-chain, solve SERVO CONTROL moment, speed, the requirement of the precision and the aspect that reduces cost.
The purpose of this utility model realizes by following technical measures: servomotor precision drive drive unit, comprise servo-driver, position transducer A, servomotor, actuator, position transducer B, its servo-driver output links to each other with servomotor, one position transducer A is set on the rotor of servomotor, the rotor of servomotor output links to each other with actuator, another location transducer B is set on actuator shaft, and position transducer A, position transducer B all link to each other with servo-driver.
In technique scheme, described actuator is a reductor.
Actuator's terminal feedback signal that the utilization of the utility model servomotor precision drive drive unit is taked, Digital Servo Driver compares according to the value of feedback and the desired value of actuator's output end position transducer, adjust the motion of motor, it can accurately realize the requirement of control command, eliminate the error in the driving-chain, solve SERVO CONTROL moment, speed, the requirement of the precision and the aspect that reduces cost.The utility model especially is suitable for the servo-drive of brushless electric machine band decelerator.
Description of drawings
Fig. 1 is the structural representation of the utility model servomotor precision drive drive unit embodiment.
Wherein: 1 servo-driver, 2 servomotors, 3 reductors, 4 position transducer A, 5 position transducer B.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Be illustrated in figure 1 as a kind of embodiment of the present utility model, servomotor precision drive drive unit, it mainly comprises: servo-driver 1, position transducer A, servomotor 2, reductor 3, position transducer B.
The output cable of servo-driver 1 connects servomotor 2, one position transducer A is set on the rotor of servomotor 2, the rotor of servomotor 2 outputs connects reductor 3, by big moment of output shaft output, another position transducer B is set behind the planetary gear speed-reduction of reductor 3 at the output axle head.
During use, servo-driver 1 is connected host computer, be used for accepting or the storage control command, the operation of servo-driver 1 control servomotor 2.Servomotor 2 feeds back to servo-driver 1 by position transducer A with the rotor real time position.Simultaneously, position transducer B gives servo-driver 1 with the position feedback of 3 of reductors.Servo-driver 1 will compare the position of servomotor 2 armature spindles and the position of reductor 3 output shafts, and the location of instruction that contrasts the host computer requirement simultaneously is a desired value, the motion of control servomotor 2.
In the above-described embodiments, can reductor be replaced with other actuator, as booster engine etc. according to the difference of executing the task.
