FAQ

Q: What kind of packaging do you use for your motors

A: Our motors are put inside the shock-absorbing foam. Each pocket has one motor so that we can make sure the motors won’t collapse each other and can endure fierce vibration during transportation.

 

Q: What are the factors that need to consider when choosing a motor?

A: When choosing a stepper motor, several factors need to be considered, including load requirements, required speed and precision, availability of power and control circuits, and cost.

 

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: Can the products be customized to the customer's requirements?

A: Yes, the specifications stated above are the standard ones, we can design and manufacture as required.
