Detailed explanation of stepping motor and stepping driver, what is stepping motor and what is stepping motor driver? Stepping Motor is a special motor used for control. Its rotation is at a fixed angle (Called'Step angle') Step-by-step operation is characterized by no accumulated errors, so it is widely used in various open-loop control. The operation of the stepping motor requires an electronic device to drive. This device is the stepping motor driver, which converts the pulse signal sent by the control system into the angular displacement of the stepping motor, or: every time the control system sends a pulse signal, the stepping motor rotates by one step through the driver. Therefore, the rotating speed of the stepping motor is proportional to the frequency of the pulse signal. Therefore, controlling the frequency of the stepping pulse signal can accurately adjust the speed of the motor; Controlling the number of stepping pulses can accurately position the motor. What is the difference between reactive stepping motor and hybrid stepping motor? First of all, the structure and materials are different. Unlike hybrid motors, reactive motors do not have permanent magnetic materials inside. Hybrid motors have certain self-locking torque. Secondly, there are differences in operating performance. The hybrid motor is relatively stable in operation, with relatively large output torque and low operating sound. Thirdly, there is a difference in price between the two motors. Reactive motors are relatively cheaper than hybrid motors, but they are not obvious. The running direction of the stepping motor is opposite to what I requested. How to adjust it? One method is to change the direction signal of the control system. Another method is to change the direction by adjusting the wiring of the motor, as shown in the following table, the wiring method of the motor, the original wiring sequence, the wiring sequence after reversing, the two-phase four-wire A, a', B, B'A', A, B, B'Or A, A', B' , B three-phase three-wire A, B, c B, A, C or A, C, B three-phase six-wire A, a', B, B', C, C'B, B', A, A', C, C'Or A, A', C, C', B, B' Five-phase five-wire A, B, C, D, E, D, C, B, A motors are two-phase four-phase six-wire and eight-wire, the drive only requires four wires, how to use it? Four-Phase hybrid motor is also called two-phase hybrid motor, but there are many ways to connect the winding outgoing line of four-phase motor. The four-outlet motor and 2 are one phase, connected to A and/A respectively; 3 and 4 are phase, connected to B and/B respectively. The six-outlet motor and 2 are one phase, connected to A and/A respectively; 5 and 6 are phase, connected to B and/B respectively. 3 and 4 are not used, they are suspended (Do not connect). Eight outgoing line motors are connected to 3, 2 and 4 are connected to A and/A respectively; 5 and 7 are connected, 6 and 8 are connected, and B and/B are connected respectively. 1 after the driver is powered on, the motor is shaking and cannot run? In case of this situation, first check whether the winding of the motor is connected to the driver incorrectly; If there is no error, check whether the input frequency CP is too high; Whether the lifting frequency design is unreasonable, refer to the lifting frequency design; The above reasons are not, it may be that the drive is burned.
