Single-chip microcomputer control stepping motor is easy to appear out of step, low-frequency vibration and vulnerable to external electromagnetic interference and influence the normal work of the stepper motor, from the characteristics of stepping motor drive and control system aspects such as the cause of the problem is analyzed, from the control of stepping motor drive system electromagnetic interference ways 'runtime instability is mainly affected by two aspects, one is caused by the mechanical properties of stepper motor itself, on the other hand is to control the drive system itself by the external environment factors and the impact of program structure, etc.
Stepper motor is the electrical pulse signal into angular displacement or linear displacement of open loop control motor, is a modern digital process, the main components of control system, has extensive application.
in the case of the overload, planetary gear 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 according to set the direction of a fixed point of view, called & other; Interval Angle & throughout; , its rotation is based on the Angle of the fixed step by step. Can be controlled by controlling the pulse number of angular displacement, so as to achieve the purpose of accurate positioning; As well as by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve the purpose of regulating.
stepper motor run time of low frequency vibration of the rotor oscillation phenomenon, would cause collisions, gear noise! The noise is caused by the intrinsic characteristics of stepper motor; Step motor has resonance point at the same time, when the rotor speed to achieve the mechanical resonance point will produce resonance and noise; Additional step motor when high frequency starting and stopping also can produce vibration and noise because of the strong impact.
the electromagnetic interference is likely to be disorder in the single-chip microcomputer control system, make SCM produce misoperation or even crash, etc. , the serious influence the stability of the stepping motor running, Explanation: solid stability; There is no change) Sex.

Single chip microcomputer control stepping motor drive system to produce electromagnetic interference of interference sources, mainly from the external power supply, internal power supply, PCB homemade interference, air surrounding electromagnetic field ( Definition: transfer physical interaction between magnetic field) Interference, external interference signal can be through public conductor, capacitor, the mutual inductance and space radiation way of adjacent wires from the interference source coupled to the sensing element.
drive system in several aspects, affect the prominent analysis:
1. The wiring is not does not affect the normal work. The same loop or not does not affect the normal work between different circuit wiring easily generate induced electromotive force, form the electromagnetic interference.
2. The power supply interference. At work, when the ac power grid load mutation generate larger amplitude of transient voltage wave through the dc regulated power supply into the electronic control circuit, which affect the stability of the single chip power supply.
3. Between single-chip microcomputer and stepping motor drive circuit, drive circuit of jamming signal through the line into the single chip microcomputer, the single chip microcomputer to produce false action, leading to the stepper motor steps more or loss occurs.
4. Stepper motor armature turn on and off frequently, when electricity, will produce larger voltage current gradient change, lead to magnetic field coupling, forming serious electromagnetic interference. When the armature winding without electricity, sudden loss of the coil in the magnetic field will produce high transient voltage into the control loop, other electronic devices in the system a considerable power impact even damaged components.
Hangzhou Xiaoshan Zhenyu Transmission Co., Ltd.'s has been able to achieve excellent performance in an extremely competitive industry.
Many websites provide additional information on the topic of electric motor suppliers. One such site worth visiting is Zhenyu Transmission.
Basically, you cannot have a planetary gear motor without having the right electric motor suppliers. Since you are going to use it regularly, be sure to invest in one that has a high quality.
