The performance of various types of micro-motors varies greatly, and its performance parameters are difficult to clarify. Generally speaking, the force energy used for driving the machine is focused on the micro-motor - Korea SPG micro-motor standard; the power supply is used to consider the output power, waveform and stability; the control micro-motor is more static And dynamic property parameters. The characteristic parameters of the first two types of motors are similar to those of ordinary motors. Only the control micromotor has its unique characteristic parameters. 3.1, working characteristics Commonly used output and input, or the relationship between one output and the other. 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. 3.2, 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. 3.3, 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. 3.4, 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. 3.5, 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 operational reliability of the micro-motor. Fourth, the application field of micro motors The micro-motor is mainly used in three fields: 1 The driving occasion without special control requirements is used as the power source for the moving mechanical load. 2 audio and video equipment. For example, in video cassette recorders, micro-motors are both a key component of the drum assembly and an important component of its capstan drive, automatic loading of the tape and cassette, and tape tension control. 3 office automation equipment, computer peripheral equipment and industrial automation equipment. Micro motors are used in disk drives, copiers, CNC machines, and robots.
