The so-called closed-loop stepper motor is the additional encoder of the stepper motor to realize the high precision and low jitter function of the servo motor, so it is called the closed-loop stepper motor. In most cases, the stepper motor is open-loop nature, that is, the motor accepts the control instructions of the PLC through the bus or other means, and does not carry out motion feedback. In this way, the structure of the entire motor system can be simpler and the cost can be lower. Compared with the open-loop control stepper motor, the closed-loop stepper motor is to add an encoder structure to the motor, so that it becomes a servo system. The motor receives the driver pulse at the same time, but also feedback the pulse to the driver and even the PLC, to achieve the control of the question and answer, and the reliability is higher. Of course, because of the increased structure, the cost of the motor is higher, and it is suitable for projects with relatively high control ... Continue reading →

Open loop and closed loop are terms often used in control systems. Open-loop stepper motors and closed-loop stepper motors are also distinguished and named according to their control systems. Therefore, to understand the difference between them, we must first understand the difference between open loop control and closed loop control, and their differences are as follows: 1. Different working principles The open-loop control system can neither detect nor correct errors. The control accuracy and the performance of suppressing interference are relatively poor, and it is very sensitive to the change of system parameters. Therefore, it is generally only used in some occasions where external influences can be ignored, or inertia is small, or precision requirements are not high. The advantage of closed-loop control is that it gives full play to the important role of feedback, eliminates unpredictable or uncertain factors, and makes the correction action more accurate and more powerful. ...

The answer is yes, the stepper motor must use a drive in order to work properly. Then why does a stepper motor need a stepper motor driver? The first reason is that the stepper motor needs a driver to regulate voltage and current. First of all, let's understand the working principle and control of the stepper motor. The basic working principle of the stepper motor is: energizing one or more stator phases, the current passing through the coil will generate a magnetic field, and the rotor will be aligned with the magnetic field; Applying voltage to different phases in turn, the rotor will rotate at a specific Angle and eventually reach the desired position. The control of the stepper motor is that the motor coils need to be energized in a specific order to generate a magnetic field with which the rotor will be aligned. There are several types of devices that can provide the necessary voltage to the coil to allow the motor to operate properly (starting with those closer to ... Continue reading →

Does the stepper motor need an encoder? The answer to this question is: Stepper motors do not necessarily require encoders, but in some applications, the use of encoders can improve the accuracy and control performance of stepper motors. Because the stepper motor is an open-loop control system, its position and speed are determined by the pulse signal sent by the controller. In the absence of an encoder, the stepper motor can only perform open-loop control according to the pulse signal sent by the controller, and cannot feedback the position and speed information of the motor in real time. This may cause errors and out-of-step phenomena during the operation of the stepper motor. The role of the encoder is that it provides a closed-loop feedback signal by tracking the speed and/or position of the motor shaft so that the motor does not lose steps. Therefore, if you want to avoid the above situation, you can choose to use the encoder to realize the closed-loop control of the stepper ... Continue reading →
