Stepper motors are widely used in various applications due to their precise control and reliability. However, one of the common issues they face is excessive vibration and noise at low speeds. This phenomenon occurs because the motor operates within a resonance frequency range, causing instability and reducing performance. To address this problem, several effective solutions can be implemented: A. If the motor is operating primarily within the resonance zone, adjusting the gear ratio or other mechanical transmission components can help avoid these frequencies. This method is often used in systems where mechanical modifications are feasible. B. One of the most popular and straightforward solutions is to use a driver with subdivision functionality. Subdivision allows the motor to move in smaller steps, which significantly reduces vibration and improves smoothness. It’s a cost-effective approach that offers great results for many applications. C. Another option is to replace the current stepper motor with one that has a smaller step angle, such as a three-phase or five-phase motor. These types of motors provide smoother operation and reduce the likelihood of resonance. D. For more demanding applications, switching to an AC servo motor is an excellent choice. Servo motors offer better control, reduced vibration, and higher efficiency. While this solution comes with a higher cost, it delivers superior performance and reliability. E. Adding a magnetic damper to the motor shaft is another alternative. This device helps absorb vibrations and improve stability. However, it may require significant changes to the mechanical design, making it less ideal for retrofitting existing systems. Choosing the right solution depends on factors such as budget, application requirements, and system complexity. By understanding the root causes of vibration and noise, engineers can implement the best strategy to enhance the performance and lifespan of their motor systems.
The moving head light series is an indispensable style of stage lighting. Washing lights and focusing lights can add more beautiful color dynamic effects to the stage and make the stage more colorful. Applicable places include various large and small stages, bars, restaurants and other places, one of the essential products for light shows. More other types of moving head lights, such as laser beam lights, phantom electrodeless lights, COB moving head lights, etc., rotate 360 degrees to make the stage more dynamic.
