The Micro Dc Motor suppliers tells you how to control the five characteristic parameters of the micro motor.
The performance of various types of micro-motors varies greatly, and the performance parameters are not uniform. Generally speaking, the driving machinery focuses on the energy and energy indicators during operation and starting; for power supply, the output power, waveform and stability should be considered. . The only way to do this is to control the micromotors with their unique characteristic parameters.
(1) Control requirements: The static characteristic curve should be continuous, smooth, and free of mutations; the dynamic characteristics are usually expressed by frequency curves or response curves. The frequency curve should be smooth and there is no sudden oscillation point; the response curve should converge quickly.
(2) Sensitivity: corresponds to the magnitude of the output of the unit input signal. Generally, it is expressed by specific torque, specific electromotive force, amplification factor, and the like.
(3) Accuracy: Under certain input conditions, the difference between the actual value of the output signal and the theoretical value represents the accuracy of the micro-motor, and the commonly used error magnitude is expressed.
(4) Impedance or resistance: In the system, the input and output impedance of the micro motor should be matched with the corresponding circuit to ensure the running performance and accuracy of the system.
(5) Reliability: It is not only the special requirements of micro-motors for control, but also for driving micro-motors and power micro-motors. The parameters such as service life, failure rate, reliability and mean time between failures are used to characterize the operational reliability of the micro-motor.
