Welcome!
The working principle of a reactive stepper motor is relatively simple, with many small teeth evenly distributed on the rotor. The stator teeth have three excitation winding resistances, and their geometric axes are sequentially offset from the rotor tooth axis. The position and speed of the motor correspond one-to-one with the number of conductive pulses and frequency. The direction is determined by the order of conductivity. Generally, reactive stepper machines with two, three, four, and five phases are predominant in the market.
Although there are still certain differences between stepper motors and imported stepper motors in certain aspects, such as high-speed torque, accuracy, etc., these differences can be ignored in most cases. Especially in terms of price, stepper motors have significant advantages, making them more competitive in the domestic market. In addition, with the continuous progress of technology and the improvement of quality, the performance of stepper motors is gradually approaching or even surpassing international brands.
As an important control component, stepper motors play an irreplaceable role in modern industry and technology. The stepper motor achieves positioning through fixed movements at each step angle, with high accuracy and positioning capability. They can precisely control the position and speed of objects, ensuring the stability and accuracy of the production process. Stepper motors have a fast response speed and can achieve high-speed motion, making them suitable for applications with high speed requirements, such as 3D printing, robotic arms, etc.
With the rapid development of microelectronics and computer technology, the control methods of stepper motors have become more flexible and diverse. The microcontroller controls the stepper motor through software, which not only improves control accuracy and flexibility, but also reduces costs. In the future, stepper motors will continue to develop towards high precision, high speed, high reliability, and intelligence to meet more complex and diverse application needs.
