Where does the step motor need
What is a step motor A: stepper motor is an actuator that converts electrical impulses into angular displacement. Popular point: when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (and the step Angle). You can control the amount of angular displacement by controlling the number of pulses, so that the target is accurate. At the same time, you can control the speed and acceleration of the motor by controlling the pulse frequency. There are three types of steps: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 15 degrees. The reaction type step is generally three-phase, can realize the big torque output, the step Angle usually is 1.5 degrees, but the noise and vibration are very large. Developed countries such as the United States and Europe were eliminated in the 1980s. Hybrid step refers to the advantage of mixing permanent magnet and reactive type. It is divided into two phases and five phases: the Angle of two phases is 1.8 degrees and the Angle is 0.72 degrees. This step is the most widely used
Many occasions are used, such as office automation (printer, copier, scanner, etc.), thread cutting workbench drag, flocking machine workbench (pores), packaging machine (length). There are also ATM machines, drawing machines, engraving machines, photo-realistic machines, spraying equipment, medical instruments precision instruments, industrial control systems, robots and so on. It is especially suitable for the application of stable, low noise, fast response, long service life and high output torque.
Step motor is widely used in the motor drive control of various kinds of equipment. For example, from the joint drive of a complex robot to the home air conditioner. The main characteristic of the step motor is that each pulse is rotated one step at a time, so the positioning accuracy is higher than that of other machines, and the drive control is simple and the overall cost is low. For the digital age control system, the step motor is a digital motor, especially for the microcomputer, so the application is more and more widely. In many places it has even replaced other motors, such as servo motors.
