Hello, what you want to ask is what is the free range of stepping conveyor? The range of freedom of stepping conveyor is 0. 1 mm to 1 mm. This is mainly determined by the characteristics of the stepping motor of the stepping conveyor. Stepping motor is a kind of motor which uses pulse signal to control the rotation angle of rotor. Its rotation angle is fixed, which is 1.8 degrees and 0.9 degrees. The freedom range of stepping conveyor refers to the minimum angle that stepping motor can rotate in a certain period of time. The rotation angle of stepping motor is fixed, so the number of revolutions of stepping motor is limited in a certain period of time. The range of freedom of stepping conveyor depends on the number of revolutions of stepping motor and the design of transmission mechanism. The more times the stepping motor rotates, the greater the freedom range of the stepping conveyor. Due to the characteristics of stepping motor, when the rotation times are too many, the rotation accuracy of stepping motor will decrease, thus affecting the running accuracy and stability of stepping conveyor. Therefore, the range of freedom of the stepping conveyor is 0. 1mm ~ 1mm, and the stepping conveyor is a kind of continuous conveying equipment, which uses the stepping motor to drive the conveyor belt to convey articles. It can accurately transport the goods to the destination according to the preset position and speed.
