How do you choose suitable DC gearmotor from our series?

+ -

Confirm the following aspects:
1. gearbox shape: cylindrical gearbox, right angle gearbox, square gearbox.
2. Gearbox type: spur gearbox,planetary gearbox, worm gearbox, square gearbox.
3. operating voltage, operating load speed, operating load torque, operating current, limited current.
4. Output shaft. 5. Encoder and cables.

Are your DC gear motors waterproof?

+ -

We will implement waterproofing, moisture-proofing, and rust-proofing protective measures according to customer requirements.

Can your motors operate in low-temperature environments?

+ -

Yes, Yes, we have implemented measures to enable the motor to operate in low-temperature environments.

Are your motors heat-resistant?

+ -

Yes, we can manufacture high-temperature-resistant DC gear motors.

Can a DC gear motor be equipped with a Hall encoder?

+ -

Yes, hall encoder is 3PPR, 7PPR, 12PPR

Which parts of your custom gear motors do you customize?

+ -

The gearbox's exterior shape, internal structure, gears, DC motor, output shaft, cables, encoder, material composition, and specifications: voltage, current, no-load speed, rated speed, rated torque, etc.

Do you have a controller/driver/encoder together with the motor?

+ -

For DC brushed Gear motor, we provide encoder. If you need motor's driver, you can find them from driver suppliers. For DC brushless Gear motor, we can provide built-in driver into brushless motor.

How do you calculate the output rated torque and output rated speed?

+ -

DC Gear Motor Output Speed=DC Motor Speed/Gear Ratio DC Gear Motor Output Torque=DC Motor Torque*Gear Ratio*Gearbox Efficiency

How do we avoid the gear broken?

+ -

First, you need to choose the DC gear motor with proper rated torque. When you use or test gear motor, the load torque is no more than motor's and gear's max torque. Avoid to stay at stall long time. If your application hits stall or uses stall torque, please let us know before building samples.

How do you avoid the motor burned?

+ -

Using the motor within the specified range. Don't keep the motor at stall continuously long time. If the DC motor's commutator is damaged or lots of carbon is on commutator, please replace a new commutator.

Can you customize motors for our project?

+ -

Yes, if our current gear motors can not meet your requirements, our R&D team will propose customized solutions. If the solutions are acceptable on your side, We will further access the prototypes costs, tooling cost and production cost.

What is parameter range of your gearmotor?

+ -

Diameter: 10mm to 63mm, rated torque: 0.01kg.cm to 1000kg.cm,gearmotor rated speed: 1rpm to 2000rpm.

Do you have after-sales service?

+ -

yes, we provide technical support after sales.

What is your MOQ?

+ -

MOQ is 1000PCS.
