Frequently Asked Questions (FAQ)

Clear answers to technical inquiries regarding customization, lead times, quality control standards, and design integration.

What is the standard lead time for custom actuator and gearmotor samples?

For basic shafts and electrical profile modifications, samples are typically completed in 7-10 working days. If a brand-new planetary or worm gearbox housing requires unique plastic injection tooling or specialized gear-hobbing dies, development spans 21-30 days.

How does your factory control acoustic performance in gear assemblies?

We employ Swiss-style gear hobbing, Japanese dynamic balancing systems, and maintain an ISO-certified soundproof testing room. Each batch is audited to ensure operational sound levels remain below 35-40 decibels at nominal load.

Do your motors and micro actuators meet CE and RoHS specifications?

Yes. All raw materials (copper wire, magnets, lubricants, lead wires, PCBs) undergo Incoming Quality Control (IQC) testing to verify compliance with RoHS and REACH standards. Finished drive assemblies are regularly certified for CE and UL marks.

Can we specify encoder configurations for high-resolution positioning?

Absolutely. Our brushless and brushed DC gearmotors (including N20 and planetary formats) support direct mounting of magnetic Hall-effect encoders or optical encoders, providing feedback for precise closed-loop speed and position control.

What gearbox reduction ratios are available for micro motors?

We offer range scales from 4:1 up to 298:1 on our 12mm and 25mm planetary gearboxes, allowing engineers to balance speed against load requirements dynamically. Standard worm configurations also offer self-locking mechanics.

How do you assure performance stability at extreme temperatures?

We test motor winding insulation and housing seals in our programmable constant temperature and humidity chambers. We also utilize specialized low/high-temperature synthetic lubricants that preserve viscosity from -40°C up to +120°C.

What is the Minimum Order Quantity (MOQ) for custom OEM orders?

Standard configurations have an MOQ of 1,000 units, while highly customized or proprietary drive systems generally require a 2,000 to 5,000-unit minimum run, depending on tooling investments and complexity.

Do you provide dynamic torque-speed testing curve documentation?

Yes. Every sample shipment or bulk delivery includes certified quality control sheets generated by our digital dynamometer systems, detailing stall torque, efficiency limits, current draw, and speed performance.
