Wiring Diagram

Tips: Three factors should be paid attention to in selection of the stepper motor

1. Stepping angle
   it is necessary to select the stepping angle of stepper motor according to the requirements of load precision. The least resolution ratio of the load is generally converted to the motor shaft, pay attention to the angle for each resolution ratio and the stepping angle of stepper motor should be equal to or smaller than the angle.
2. Static torque
   Select the static torque according to the load of stepper motor while load can be divided into inertia and friction load. When directly starting the stepper motor (generally from the low to high velocity), the considerations into the two kinds of load are given. When starting the motor at acceleration, give considerations into the inertia load; when the motor rotates at constant velocity, only give considerations into the friction load. Generally, the static torque shall be within 2-3 times of the friction load.
3. Current
   As for the stepper motors with the same static torque, there is great difference in their motion characteristics due to the difference in current parameters. The current of stepper motor can be judged according to the torque frequency characteristic curve diagram.
