FAQ

Q: May I know which payment will be accepted by your company?

A: We accept T/T payment. Paypal payment is only for the sample.

 

Q: What is resonance in a stepper motor system?

A: Resonance occurs when the natural frequencies of the motor and driven load coincide, leading to excessive vibrations and potential loss of steps.

 

Q: How can I get to your factory?

A: Our factory is near Shanghai Hongqiao Airport. We can pick you up at the airport.
