How to Control with Arduino/ESP32:
-
Direct Connection (No Driver):
-
Works for low-power applications (≤ 500mA)
-
Connect to Arduino PWM pins (for speed control)
-
-
With Motor Driver (L298N, TB6612, etc.):
-
Required for higher current or bidirectional control
-
🔹 Applications
✔ Mini Robots (Line followers, obstacle avoiders)
✔ Camera Sliders & Pan-Tilt Mechanisms
✔ Smart Locks & Automated Doors
✔ DIY Drones & RC Toys
✔ Medical Devices & Small Automation
🔹 Torque & Speed Performance
| Voltage (V) | No-Load Speed (RPM) | Stall Torque (gf.cm) |
|---|---|---|
| 3V | ~150 RPM | ~100 gf.cm |
| 6V | ~300 RPM | ~200 gf.cm |
| 12V | ~600 RPM | ~400 gf.cm |
*(Higher voltage = faster speed but more heat; do not exceed 12V!)*
🔹 Mounting & Accessories
-
Wheel Adapters: 3mm shaft-compatible wheels
-
Encoder Disks: For speed/position feedback
-
Motor Brackets: For secure mounting in projects
🔹 FAQ (Frequently Asked Questions)
❓ Can it run continuously?
✅ Yes, but avoid stall conditions (overheats if blocked).
❓ Is a gearbox included?
✅ Yes, this is a pre-assembled gear motor (no extra gearbox needed).
❓ How to increase torque?
🔧 Use a lower voltage (3V–6V) or gear it down further.
❓ Can I use it with a LiPo battery?
✅ Yes, but use a 3.7V (1S) or 7.4V (2S) LiPo (with voltage regulator if needed).
🔹 Why Choose This Motor?
✔ Small but powerful – Great for tight spaces
✔ Dual shaft – More mounting options
✔ Metal gears – Longer lifespan than plastic
