Frequently Asked Questions
How do you ensure gear motor longevity?
We utilize high-grade carbon brushes or brushless architectures combined with specialized synthetic lubricants. Each batch undergoes rigorous aging tests under 1.5x rated load to identify potential wear patterns before mass shipping.
Can you customize the shaft and mounting?
Absolutely. We offer custom D-cut, cross-drilled, or splined shafts. Our CNC facility can modify housing dimensions and mounting patterns to fit your existing chassis without costly redesigns.
What is the typical MOQ for custom orders?
While we support wholesale volume, our MOQ for initial custom prototypes is flexible to support the R&D phase of our partners. Mass production typically starts at 1,000 units.
How do you handle electromagnetic interference (EMI)?
We offer optional integrated varistors, capacitors, and shielded housing solutions to minimize EMI, ensuring your device passes strict EMC testing for medical and consumer electronics.
