Frequently Asked Questions

Q: What voltage does this motor need?
A: These motors operate optimally at 3V-6V DC. While they can function outside this range, we recommend staying within it for best performance and longevity.

Q: What are the shaft specifications?
A: Each motor features a:

• 3mm diameter D-shaped shaft

• 9mm shaft length
  This design ensures secure attachment for wheels, gears, and other components.Or custom the motor shaft as your requirements.

Q: What power source should I use?
A: These versatile motors work with various power options:
✓ 2x AA batteries (3V)
✓ 4x AA batteries (6V)
✓ LiPo/Li-ion batteries (3.7V-5V)
✓ Bench power supplies

Q: What's the RPM at 6V?
A: At 6V, you can expect:

• No-load speed: ~600 RPM

• Loaded speed: ~500 RPM (at rated torque)
  For precise measurements, we recommend testing with your specific load using our included performance graphs as reference.

Pro Tip: For speed control, pair with a PWM controller to fine-tune performance while minimizing power consumption.
