🔧 JGA25‑370 Speed Reduction Motor – 6‑24V DC, 16‑1360 RPM, High Torque Metal Gearbox
Ever built a robot arm that just didn't have enough low-end grunt? Or a tiny conveyor that ran too fast to control? This JGA25‑370 DC gear motor fixes that. Run it from 6V to 24V, dial in exactly the speed you need (16 to 1360 RPM), and let the all‑metal gear train handle the heavy pulling. Whether it's a CNC router, an automated packaging line, or a DIY rover, this little powerhouse delivers industrial‑grade torque without hogging space.
⭐ Key Features of the JGA25‑370 High Torque Motor
-
Wide voltage flexibility (6V‑24V DC) – Works with most robot controllers, battery packs, or bench supplies. No need to swap motors when you change your project's voltage.
-
Adjustable speed precision (16‑1360 RPM) – Use PWM or a simple speed controller to get slow, high‑torque rotation for conveyors or fast motion for small vehicles.
-
Heavy‑duty metal gearbox – All internal gears are metal, not plastic. That means less backlash, longer life, and reliable power transmission even in dusty or high‑load environments.
-
Compact JGA25‑370 form factor – Only about as big as your thumb, but delivers surprising torque. Fits easily into drones, small robots, and tight machine compartments.
-
Forward & reverse capable – Change polarity to reverse direction instantly. Perfect for robotic arms, sliding gates, or any bidirectional application.

❓ Frequently Asked Questions
🔩 How much torque does this JGA25‑370 motor actually produce?
Torque varies with voltage and speed. At 12V and lower RPM (around 100‑200 RPM), you can expect roughly 3‑5 kg·cm of stall torque. The metal gearbox multiplies the motor's native torque significantly. For exact torque curves by voltage, check our datasheet link above or message us – we'll send you the spec sheet.
⚡ Can I run this motor directly from an Arduino or Raspberry Pi GPIO pin?
No – the motor draws up to 100mA no‑load and much more under load. Never connect it directly to a microcontroller pin. You'll need a motor driver (like L298N, L9110S, or TB6612) with a separate power supply for the 6‑24V input. The driver's logic side can then connect to your Arduino or Pi.
🔊 How loud is the metal gearbox? Is it quiet enough for a desk robot?
Metal gear motors are generally louder than plastic‑gear ones, but the JGA25‑370 is reasonably quiet for its class. At low RPM (under 200), you'll hear a smooth whir. At high speeds, it's more noticeable, but still fine for most home workshops or garage projects. If absolute silence is needed, consider a plastic gear version – but it won't last as long under heavy loads.
⏱️ Can this motor run 24/7? What about heat?
Yes, it's designed for industrial‑grade continuous duty. The metal housing and gearbox dissipate heat well. At full load and 24V, the motor body will get warm (around 50‑60°C / 122‑140°F) – that's normal. If it becomes too hot to touch, reduce the duty cycle or add a small heatsink. For 24/7 operation, stay within 80% of the maximum rated voltage.
📏 What's the exact mounting hole pattern and shaft length?
The JGA25‑370 has two M2.5 screw holes with a 16mm center‑to‑center spacing. The 4mm diameter D‑cut shaft extends about 12mm from the gearbox face. We recommend using our dimension drawing (available upon request) if you're designing a custom bracket or 3D‑printed mount.
🔄 Does it come with a speed controller or PWM module?
The motor itself does not include a controller. You'll need an external PWM speed regulator or a motor driver board. However, we do sell compatible 6‑24V PWM speed controllers separately – check our store under "Motor Controllers". If you order both together, we can combine shipping.
