How to realize the accuracy of stepping motors? Stepping motors are used more and more frequently. Now it has passed the era of mass production and everything has begun to be accurate. Many precision instruments have been widely used in various industries, but you can't forget the small stepping motor behind the scenes. He is a person who has made great contributions. Why can stepping motors be used in precision instruments? Next, I will tell you about the characteristics of this stepping motor. Stepping Motor has the advantages of large torque, small inertia, high response frequency and the like, and has the superior characteristics of instantaneous starting and rapid stopping. Compared with other driving elements, it has obvious advantages: displacement or speed can be accurately controlled without feedback; The output angle or displacement accuracy is high, and the error will not accumulate; The control system is simple in structure, compatible with digital equipment and cheap. It has a fixed number of steps per revolution, which can accurately control the stepping and receiving digital quantity. However, there are three types of stepping motors: permanent magnet (PM), Reaction formula (VR)And hybrid (HB). Permanent magnet stepping is generally two-phase, with small torque and volume, and the stepping angle is generally 7. 5 degrees or 15 degrees; Reactive stepping is generally three-phase, which can realize large torque output, and the stepping angle is generally 1. 5 degrees, but the noise and vibration are very large. It has been eliminated in 1980s in developed countries such as Europe and the United States; Hybrid Stepping refers to the combination of the advantages of permanent magnet and reactive type. It is divided into two phases and five phases: the stepping angle of the two phases is generally 1. 8 degrees and the five-phase step angle is generally 0. 72 degrees. This stepping motor is the most widely used. There are still a lot of knowledge about stepping motors, but I won't explain them one by one here.
