Custom OEM/ODM — Need a Different Specification?
If the standard RF-300CA series does not match your exact requirements, our engineering team can design and manufacture a custom motor tailored to your application.
What We Customize:
- Voltage: Custom nominal voltage (0.5V - 12V range)
- Speed: Custom RPM to match your load requirements
- Torque: Custom winding for higher starting or running torque
- Shaft: Diameter, length, D-cut, flat, keyway, gear integration
- Mounting: Custom hole pattern, flange, bracket
- Wire & Connector: Custom lead wire length and connector type
- Brush Type: Precious metal or carbon brush optimization
- Body Length: Miniaturize or extend body length
- Custom Branding: Laser marking, label design
How to Request Custom Motor:
- Step 1 — Send Your Requirements Describe your application: voltage, speed, torque, load type, duty cycle, dimensions, and any mounting constraints.
- Step 2 — Engineering Analysis Our R&D team evaluates feasibility and proposes optimal winding specs and mechanical configuration.
- Step 3 — Sample Production We manufacture samples for your testing and performance validation.
- Step 4 — Mass Production Upon approval, we proceed to bulk manufacturing with consistent quality control.
