24mm 3V micro DC motor RF-320 (precious metal brush) and RK-320 (carbon brush motor) — your versatile micro DC motor solution for electric lock, toy, fan, small pump and smart home applications. The RF-320 motor delivers 2900 RPM at 3V with 20.1mm body length and 25g weight, ideal for VCD motor, electric valve motor and office automation. The RK-320 carbon brush motor delivers 3400 RPM for high-speed toy motor and small pump motor applications. Both models operate at 1-4V voltage range with 2.0mm standard shaft. Available in 24mm DC motor form factor with 2-M2*0.4 mounting. The carbon brush version offers superior durability for continuous duty fan motor and small pump motor applications. OEM and ODM customization available.

If the standard RF/RK-320 series does not match your exact requirements, our engineering team can design and manufacture a custom motor tailored to your application.

• 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, cup mount
• Wire & Connector: Custom lead wire length and connector type
• Brush Type: Precious metal or carbon brush selection
• Body Length: Adjust body length for specific requirements
• Custom Branding: Laser marking, label design

1. Step 1 — Send Your Requirements Describe your application: voltage, speed, torque, load type, duty cycle, dimensions, and any mounting constraints.
2. Step 2 — Engineering Analysis Our R&D team evaluates feasibility and proposes optimal winding specs and mechanical configuration.
3. Step 3 — Sample Production We manufacture samples for your testing and performance validation.
4. Step 4 — Mass Production Upon approval, we proceed to bulk manufacturing with consistent quality control.
