Technical features and control strategies of integrated stepper motors

1.A brief introduction to integrated stepper motors ‌Integrated stepper motors‌ are devices that integrate motors and drivers into one, and control the rotation angle of the motor through electrical pulse signals. Each pulse signal causes the motor to rotate a fixed step angle, usually 1.8 degrees or 0.9 degrees. Integrated stepper motors have two driving modes: full step and half step. Full step means that each pulse signal causes the motor to rotate a step angle, while half step means that each step angle is divided into two half steps, which control the forward and reverse rotation of the motor respectively, thereby achieving more precise control‌.

2.Working principle of integrated stepper motors ‌The working principle of integrated stepper motors‌ is to achieve rotation by controlling the magnetic field of the motor, specifically by controlling the movement of the motor through digital signals. Integrated stepper motors use a fully digital control method, integrating the control circuit and the motor body, and controlling the movement of the motor through digital signals. The controller sends a series of pulse signals to the motor, and the frequency and number of these signals determine the speed and direction of rotation of the motor.

3.Technical features of integrated stepper motors 1.Integrated design: The integrated stepper motor integrates the control circuit and the motor body, reducing external equipment and wiring, reducing the complexity and failure rate of the system, and improving the reliability of the system and the convenience of installation and maintenance. 2.High-precision control: The integrated stepper motor uses a high-precision sensor to detect the position and speed of the motor in real time, and controls the movement of the motor through digital signals, which can achieve high-precision positioning and control. In addition, the closed-loop control technology further improves the stability and accuracy of the system, reduces the phenomenon of step loss, and improves the positioning accuracy and repeat positioning accuracy of the system. 3.High efficiency and energy saving: The integrated stepper motor adopts a digital control method, which can effectively save energy and improve the efficiency and life of the motor. The design of the motor and the driver is optimized, the power conversion efficiency is improved, the energy consumption is reduced, and it meets the requirements of green environmental protection. 4.Self-protection function: The integrated stepper motor has built-in overcurrent protection, overheating protection and other safety protection functions, which can effectively prevent the motor from being damaged by external factors and improve the service life and safety of the motor. ‌5.Intelligent operation‌: Supports multiple control protocols and interface standards, can achieve seamless connection with host computers or PLCs and other devices, and facilitates users to conduct remote monitoring and debugging. Intelligent operation helps reduce energy consumption and maintenance costs and improve the overall economic benefits of equipment‌. ‌6.Electromagnetic compatibility characteristics‌: Integrated stepper motors have good electromagnetic compatibility characteristics, which enhances the system's anti-interference ability to electromagnetic interference and environmental noise‌. ‌7.Application scenarios‌: Integrated stepper motors are widely used in industrial automation, medical equipment, smart homes and other fields. In industrial automation, it can be used for automatic control systems, industrial machinery, etc.; in medical equipment, it can be used for the control and positioning of equipment such as CT and nuclear magnetic resonance; in smart homes, it can be used for smart curtains, smart door locks, etc.‌.

4.Control strategy of integrated stepper motors 1‌.PID control‌: PID control is a simple and practical control method that calculates the control deviation by comparing the given value and the actual output value, and the proportion, integral and differential of the deviation are linearly combined to form the control quantity to control the controlled object. PID controller has the advantages of simple structure, strong robustness and high reliability, but it cannot effectively deal with uncertain information in the system. Therefore, it is often used in combination with other control strategies to form a new type of composite control with intelligence. ‌2.Adaptive control: Adaptive control is a branch of the field of automatic control developed in the 1950s. It is mainly used in situations where dynamic characteristics are unknown or unpredictable changes occur. Adaptive control can overcome the influence of changes in motor model parameters, improve the drag torque characteristics of the motor through closed-loop feedback and adaptive processing, and achieve more precise position control and smoother speed. Adaptive control is often used in combination with other control methods to solve the limitations of pure adaptive control. ‌3.Subdivision technology: By improving the drive circuit, a complete step angle is subdivided into multiple smaller steps to improve the smoothness and positioning accuracy of the motor operation. This technology can significantly improve the performance of stepper motors and reduce vibration and step loss. ‌4.Current control technology: The current size of the motor winding is accurately controlled by the intelligent driver, which can not only improve the dynamic performance of the motor, but also reduce heat and noise, and extend the life of the motor. ‌5.Vector control technology‌: Similar to the control strategy of AC servo motors, it optimizes the torque output and efficiency of the motor by calculating and adjusting the current vector of each phase. This technology can significantly improve the performance of stepper motors and make them perform well under complex working conditions. ‌6.High-speed communication interface‌: Modern stepper motor controllers use high-speed communication protocols (such as CANopen, EtherCAT, etc.) to achieve efficient data exchange and real-time control with the host computer. 7.Intelligent algorithm integration‌: Advanced control algorithms such as PID control, fuzzy logic control, and adaptive control are used to improve the dynamic response of stepper motors and reduce vibration and step loss. These intelligent algorithms enable stepper motors to perform well in complex environments.
