FAQ

Q: What certifications do you hold?

A: We hold ISO9001 and ISO14001 certifications, ensuring our commitment to quality management and environmental standards. Additionally, all our motors are CE certified, guaranteeing compliance with safety and performance regulations.

 

Q: What are the typical applications of stepper motors?

A: Stepper motors find common applications in CNC machines, the 3D printing industry, automated test equipment, and various other industries that require precise control of motion and positioning.

 

Q: How does a stepper motor operate?

A: A stepper motor operates by receiving a sequence of electrical pulses that cause it to rotate in fixed angular or step increments. Each pulse moves the motor by a specific distance or angle, allowing for precise control over its position and speed.

 

Q: What is the difference between a closed-loop and an open-loop stepper motor system?

A: In an open-loop system, a stepper motor operates without feedback, relying solely on the input pulses for positioning. In contrast, a closed-loop system incorporates an encoder or position feedback device that provides feedback to the controller. This feedback enables better accuracy and allows for error correction, resulting in improved performance and positioning accuracy.

 

Q: What is your main market?

A: Our main market includes Europe, North America, South America, Australia, the Middle East, etc.
