Subdivision of stepping motor the operation characteristics of stepping motor are closely related to its stepping driver, which can get rid of the defects of stepping motor according to the improvement of controller technology.
Depending on other controller methods, the classification controller method can not only reduce the step angle of the stepping motor and improve their respective rates, but also reduce or eliminate high-frequency vibration, making the motor operation more stable and symmetrical.
Stepping Motor diagram, in general, the control function of classification controller is the most suitable.
Due to the common low-grade stepping motor servo control system frequently reported by servo motor, the internal control system alternating current is relatively reduced with the increase of motor speed, which leads to step loss.
Therefore, in industries where the speed and precision regulations are too low, it is very common to use classification controllers with high precision, classification is that the controller divides each pulse width transmitted by the leading equipment into exponential pulse width according to the classification index set by the controller, and describes that the stepping motor has 200 pulse width per revolution, if the stepper motor controller is classified as 32, then the stepper motor controller must rotate 6400 pulse stepper motors before turning the whole circle.
The general classification is 2, 4, 8, 16, 32 overseas. For the stepping system, the key is the two-phase hybrid stepping motor and the relative classification controller.
But in China, many customers areClassification'
I don't know very well yet. Some just think that classification is to improve precision. In fact, the key to classification is to improve the operation characteristics of motors.
Shenzhen ruite electromechanical Technology Co. , Ltd. is located in Shenzhen, Guangdong province, it is a stepping motor manufacturer integrating research and development, production and sales of stepping motor drivers, servo drivers, stepping motors, servo motors and spindle servo motors.
It is shown that the classified operation of stepping motors is maintained by the phase current of the stepper motor precisely controlled by the controller. Taking a two-phase motor as an example, if the power phase current of the motor is 3A, if the basic controller is applied to control the motor, the alternating current in the winding resistance will change from 0 gene to 3A or from 3A gene to 0 for each step of the motor's operation, and the phase current will change greatly, it will definitely cause vibration and noise in the operation of the motor.
Stepping Motor diagram, if the classification controller is applied, the controller will control the motor under the condition of 10 Classifications. For each micro step of the motor operation, the alternating current in the winding resistance can only change by 0.
3A but not 3A, and alternating current needs to be periodically changed by sinusoidal curve, which will improve the vibration and noise of the motor a lot. Therefore, the characteristic advantage is the real advantage of classification.
Because the classification controller needs to accurately control the phase current of the motor, the stepping motor controller should have high technical standards and process regulations, and the profit will be higher.
