Micromotor Operating Characteristics

1. Working characteristics

Commonly used output and input, or the relationship between one output and another. From the 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 size of the output of the unit input signal. Generally, it is expressed by specific torque, specific electromotive force, amplification factor, and the like.

3. Precision

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, which is represented by the commonly used error magnitude.

3. 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.

4. Reliability

Not only is the special requirement for controlling micromotors, but also for driving micromotors and power micromotors. The parameters such as service life, failure rate, reliability and mean time between failures are used to characterize the reliable operation of the micromotor.
