Servo motricium etiam dicitur supplicium, in automatic imperium ratio, adhibetur ut actuators, quod accepit electrica signum in angulari obsessio vel angulari velocitas output de motricium hastile. In medio de servo motricium rotor est permanens magnes, tres-phase electrica coegi imperium u / v / windback in hoc agro, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor est, ad adjust secundum quod Rotor Rotor, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor est, ad adjust secundum quod Rotor Rotor, ad adjust in Rotor Rotor, ad adjust in Rotor Rotor, ad adjust in rotor rotor, in eodem tempore, ad adjust in Rotor Rotor est, ad adjust in Rotor Rotor, ad adjust secundum quod in Rotor Rotor. The precision of servo motor is determined by the precision of the encoder (Line number)That is the function of the servo motor itself has a pulse, it every rotation Angle, send out the corresponding number of pulses, such servo drive and servo motor encoder pulse forming the echo, so it is a closed loop control, step motor is open loop control.
stepper motor is the electrical pulse signal into angular displacement or line displacement of the stepper motor open-loop control yuan, in the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor, set the direction of a fixed Angle, called & other; Intervallum angulus & per; , Rotatio eius fundatur angulo certum gradus per gradus. Potest regi potest pertransit pulsus numerus angularis obsessio, ut ad consequi ad accurate positioning, tum per moderantum pulsus frequency ad imperium motor gyrationis celeritate et accelerationem, ita ad consequi ad celeritate et accelerationem, ut ad consequi ad celeritate et accelerationem, ut ad consequi ad celeritate et accelerato, ita ut ad consequi ad celeritate et accelerationem, ut ad consequi ad celeritate et accelerationis, ita ut consequi ad celeritate.
stepper motor before use to check what are the main points, the following let small make up instructions for everyone:
1. Strong control signal lines, industrial site best shield to consider (If use twisted pair), don't start in all of the need to connect the line, only to make the most basic system, after running well, and then gradually connection, must understand grounding method, or is not empty.
2。 The power supply voltage is appropriate (Overpressure is likely to cause the damage to the driver module)For the input dc + / -Polarity must not wrong, stepping motor drive motor model or current value is appropriate (At the beginning not too big)。
3。 Running half an hour to closely observe the state of the motor, such as movement is normal, voice and temperature rise, found the problem immediately stop adjustment.
IV. Antius motricium non sit certa, interdum apparebit hoc situ, quae est normalis, quia in hoc tempore causa fortis resonatur motricium et intrare in statum de gradu motor fixum.
V. Nam quinque tempus stepper motricium, phase iniuriam, motricium non operatur.
Differentia inter gradus motricium et servo motricium est:
I, in alia control praecisione. Pentium Motor tempus et virga, magis eius praecisione altior et servo motricium ad producat suum fragmen encoder, magis encoder scale, superiore praecisione.
II, potestate in alia via; Una est aperta ansa imperium, et clausa loop potestate.
III, humilis frequency characteres diversis; Stepper motor at low speed is easy to appear low frequency vibration phenomenon, when it is commonly used while working in low-speed damping technology or segmentation technology to overcome the low frequency vibration phenomenon, servo motor running smoothly, even in the low speed also won't appear when the vibration phenomenon. AC servo ratio habet resonatur suppressionem munus, can operiet mechanicas rigiditatem, et ratio habet munus frequency resolutio (FF), potest deprehendere mechanica resonare puncto ad faciliorem ratio temperatio. Et torque-celeritate characterem in
IV, aliud; Ante Motor cum altior celeritas et decrementum de output torque of ac servo motricium ad constant torque output.
V, ONERO Capacity; Stepper motricium est plerumque non habet onload facultatem et AC motricium habet fortis facultatem de cultro.
VI, aliud currit perficientur; Stepper motor control for the open loop control, start frequency is too high or too much load step is easy to lose or locked-rotor phenomenon, stop when high speed impact occurred easily, ac servo drive system for closed-loop control, the drive can be directly to the motor encoder feedback signal sampling, internal position loop and speed loop, general won't appear step motor lose step or overshoot phenomenon, more reliable control performance.
VII, celeritas responsio perficientur diversis; Ante motricium celeritas accelerate ex 0 ad opus postulat centum milliseconds, et melior accelerato perficientur de ac servo ratio, plerumque tantum paucis milliseconds, potest adhiberi velox satus-subsisto imperium occasiones.
Locus in unum est narrat, ac servo ratio in multis perficientur melius quam ingreditur motricium, sed pretium est non idem.
