A: For low cost samples with quantity no more than 5pcs, we can provide them for free with freight paid by buyer (if clients can provide their courier account or arrange courier to pick them up from our company, it'll be okay with us). And for others, we'll charge sample cost and freight. It's not our aim to earn money by charging samples.
If it matters, we can make a refund once got the initial order.
Q: May I have a motor with 12V/5000RPM/25mm, fan/car motor or could you tell me what information I should provide to get the motor I want?
A: Normally we recommend the motors based on the size constraints like diameter, length, width, the shaft diameter, rated voltage, no load speed and stall torque or on load speed and on load torque, lifetime requirements and noise level etc. And different motors might be needed for the same application if with different design. If you can send us a picture of your sample with size information, your existing spec or the detailed requirements we mentioned above, we'll see what we can do. The more information you provide; the better for us to provide what you exactly need.
