If you do not know the torque you need, please describe the application of the motor on your side, and the reserved space for the motor.
We have many projects with different motors, we might provide similar proposals for test, then we will know if the torque is enough.
To choose a suitable dc gear motor, you need to know your requirements about voltage, speed(load speed or free load speed), and rated torque.
Sometimes we can work out proposals based on these requirements. If you have some space limit, or you also have requirements about noise or lifecyle, we can improve these proposals.
For goods with express, you could let us know if you have a shipping account like DHL, Fedex etc, we will ship out the goods directly through your account when they are ready. If you do not have an account, we will ship through our agent account. It usually takes 3-5 days for these express.
For goods with air or sea shipping, we will ship to the close port to your location, you just need to make the clearance when the goods arrives at the port.
DongMing offers a 1-Year Warranty on ALL gear motors. Free replacement within warranty period if any quality-related issues.
For samples, we would be glad to offer 5-10pcs samples for test.
For production, our MOQ is 1000pcs per lot.
For samples, it usually take 2-3 weeks after order confirmed. For production, it usually takes 35 days after order confirmed.
For most long-term cooperated clients, we can shorten the production lead time with knowing forecast in advance.
Paypal payment for samples is welcome.
For production, bank transfer is acceptable. To support our customers, we can accept 50% deposit, and balance before shipment.
For samples, we usually quote an ex-work price.
For production, we usually quote a FOB Shenzhen price
Sure, when we work out suitable proposals and the proposals are acceptable for you, we will go into sample process.
We will make samples according to your full requirements. Before we ship out the samples, we will test the samples on our machine, offer a sample datasheet together.
This need depend on the cycle way and applications. We have many projects with lock, which has a long lifecyle. All the gear motor are not allowed to stall use, in this condition, all our gear motors should with enough life-cyle.
If you wanna a extreme long lifecyle, you can use a brushless dc motor with planetary gearbox. This is the best match for those applications with long lifecyle.
To reduce the noise of the motor, we need to know where the noise come out. If it comes from the driving motor, we may use a lower speed motor, or use special oil and bearings for the motor.
If it comes from the gearbox, we may try to choose a planetary gearbox, or use plastic gears, or use spcial oils.
We can provide solutions on reducing motor noise accordingly.
