    Tips: Half step, full step and subdivision of stepper motor driver

    The motor drive system consists of a motor and a driver. The performance of the stepper motor drive system depends on the performance of the stepper motor itself and the advantages and disadvantages of the stepper motor driver. The research on the stepper motor driver is almost synchronized with the research on the stepper motor.

    • Half-step drive
      When single phase excitation occurs, the motor shaft stops at the full-step position. When the driver receives the next pulse and energizes another phase and maintains the original excitation state, the motor shaft will move half a step angle and stop in the middle of two adjacent full-step positions. In this way, the two-phase coils are performed periodically. The single-phase then dual-phase excitation stepper motor will rotate in a half-step manner of 0.90 degrees per pulse. All the full/half-step drivers provided by Lisan Electromechanical can be driven by full-step and half-step, which can be selected by the DIP switch of the driver. Compared with the full-step type, the half-step type has twice the accuracy and low-speed vibration. Therefore, when the full/half-step driver is actually used, the half-step mode is usually used.
    • Full-step drive
      In the whole stepping operation, the same stepping motor can be equipped with a full/half stepping driver or a subdivision driver, but the operation effect is different. The stepping motor driver excites two of the two-phase stepping motor according to the pulse/direction command. Coil. Each pulse of this drive mode will make the motor move a basic step angle, which is 1.80 degrees
    • Subdivision drive
      The subdivision drive mode has two advantages: low-speed vibration is small, and the positioning accuracy is high. For stepping applications that require low-speed operation (that is, the motor shaft sometimes works at less than 60 rpm) or the positioning accuracy is less than 0.90 degrees, the subdivision stepping motor driver is widely used. The basic principle is based on the sine and cosine steps. Precisely control the current of the two coils of the motor, so that the distance of the step angle can be divided into several subdivisions. For example, the 16 subdivision drive mode can make the stepping motor with 200 standard steps per circle reach 25000 steps per circle with the highest operating accuracy.

    Exactly what I needed.
    I ordered this 2 phase digital stepper motor driver as a replacement for old one which would not work properly with my NEMA23 stepper motor. After switching to this, everything went smooth. It is cheaper than other suppliers, and I will buy more in the future.
