| Frequently asked questions and answers: |
Q: 1. What dc motor/gear motor do you provide?
A: Full range of small gearbox dc motor, including spur gearhead dc motor, worm gearbox electric motor, and planetary gear reducer electric motor; diameters from 6 mm, 8 mm, 10 mm, 12 mm, 13 mm, 16 mm, 20 mm, 22 mm, 24 mm, 28 mm, 32 mm, 36 mm, 37 mm, 42 mm, 45 mm, 57 mm (from 0.24 inch to 2.244 inches); output speed 5 rpm to 3000 rpm; gear reduction ratio 5-1500, output torque from 1gf.cm to 500kgf.cm ( from 0.098 mN.m to 49 N.m; from 0.014 oz.in to 7000 oz.in). Long lifespan and reliable smooth running.
Q: 2. Is it possible for you to develop new motors if we can provide tooling costs?
A: Yes. Please kindly share the detailed requirements such as performance, size, annual quantity, target price, etc. Then we'll make our evaluation and provide you with the proposal.
Q: 3. Can I get some samples?
A: Most of our samples are free for you, some expensive motors we charge double the price as the bulk order price.
We only deal with bulk orders, many consumer customers only want 1 or 2 for replacement, so we set this rule to select target customers. :)
Don't worry, the samples charge will be refunded as payment of motors later when you place a mass production order.
Q: 4. When you will reply to me?
A: Our customer service staff will reply to you within 12 hours.
Q: 5. Can you send me a price list?
A: For all of our small dc motors and mini gear motors, they are customized based on different requirements like lifetime, noise, voltage, shaft, etc. The price also varies according to different quantities. So it's difficult for us to provide a price list. If you can share your detailed requirements and quantity, then we can send you the specified dc electric motor pricing.
Q: 6. How to order?
A: Send us an inquiry → Receive our quotation → Negotiate details → Confirm the sample → Sign contract/deposit → Mass production → Cargo ready → Balance/Delivery → Further cooperation.
Q:7. What's the lead time for regular orders?
A: For regular dc motor and gear motor orders, the standard lead time is about 25-40 days and the lead time varies based on a different model, period, and quantity.
Q: 8. What are the payment terms?
A: We accept payment by T/T, PayPal. Initial payment 30-50% in advance, shipping against balance payment. We can also accept other payment terms after we have established a good long-term cooperative relationship.
