The same stepping motor can be equipped with full/half-step drivers

80 Degrees (a standard two-phase motor has a total Wholesale Blower Motor Manufacturers of 200 step angles per revolution).1125u0026deg;). Full-step drive In full-step operation, the same stepping motor can be equipped with full/half-step drivers or subdivision drivers, but the operating effects are different. Each pulse of this driving mode will cause the motor to move a basic step angle, which is 1. Half-step drive In single-phase excitation, the motor shaft stops to the full step position.

In the middle of two adjacent full-step positions. Subdivision drive The subdivision drive mode has the advantages of minimal low-speed vibration and high positioning accuracy. For stepping applications that sometimes require low-speed operation (that is, the motor shaft sometimes works below 60rpm) or the positioning accuracy is required to be less than 0. For example, the sixteen subdivision driving mode can make the stepping motor with 200 standard steps per revolution reach the running accuracy of 200*16=3200 steps per revolution (ie 0. After the driver receives the next pulse, if the other phase is energized and remains in the original excitation state, the motor shaft will move half a step angle and stop.

In this way, the two-phase coil is cyclically single-phase and then the two-phase excitation stepper motor will rotate in a half-step manner of 0. The stepper motor driver cyclically energizes the two coils of the two-phase stepper motor according to the pulse/direction command (that is, the coil is charged to set the current). 2.90 degrees per pulse..Stepper motor driver 3 major driving methods: 1. The basic principle is to perform precise current control on the two coils of the motor according to sine and cosine-shaped steps, so that the distance of a step angle is divided into several subdivided steps. 3.

All the full/half-step drivers supplied by Handebao Motor can perform full-step and half-step drives, which can be selected by the dial switch of the driver. The main difference between the three drive modes, full-step, half-step, and subdivision, lies in the control accuracy of the motor coil current (ie, the excitation mode). Compared with the full-step mode, the half-step mode has the advantages of twice the accuracy and less vibration during low-speed operation, so the half-step mode is generally used when the full/half-step driver is actually used.90 degrees, the subdivided stepper motor driver is widely used
