FAQ

Q: What are the applications of stepper motors?

A: Stepper motors find widespread use in various applications, including CNC machines, the 3D printing industry, automated test equipment, robotics, precision positioning systems, camera and lens control, medical equipment, etc.

 

Q: How do you ensure quality control?

A: Ensuring quality control is a top priority for us. We implement stringent quality control measures from the initial stages to the final inspection. Every product undergoes meticulous testing and inspection before being carefully packed for shipment.

 

Q: How does a stepper motor work?

A: A stepper motor operates through the reception of a sequence of electrical pulses. These pulses cause the motor to rotate in fixed angular or step increments. With each pulse, the motor moves a precise distance or angle, enabling accurate control over the motor's position and speed.

 

Q: What payment methods are accepted by your company?

A: Our company accepts T/T  as the primary mode of payment. For sample orders, we also accept payment through PayPal.
