Greartisan DC 12V 200RPM Gear Motor - High Torque Micro Speed Reduction Motor with All-Metal Gears and D-Shaped Output Shaft

This Greartisan DC 12V gear motor delivers 200 RPM with a 1:24 reduction ratio and a rated torque of 2.2 Kg·cm. It features all-metal gears, a pure copper wire rotor, and a D-shaped output shaft made from hardened steel. Designed for applications like vending machines, pan-tilt cameras, slot machines, automatic doors, and small robots, this motor supports both clockwise and counterclockwise rotation and allows speed reduction (cannot increase speed). It runs quietly and can drive up to 15 kg at 10 RPM.

What are the key specs of this 12V gear motor?

What makes the construction of this motor durable?

The gearbox uses all-metal gears that resist high temperatures and abrasion, offering strong load capacity and long service life. The rotor is wound with pure copper wire using precision winding technology, which increases power output by an estimated 30% compared to standard windings. The D-shaped output shaft is made of high-hardness steel with good toughness and impact resistance, improving bearing quality and overall motor longevity.

How do you wire and operate this motor?

Connect the red lead to positive and black lead to negative. Reversing the polarity reverses the rotation direction. The motor can only have its speed reduced (not increased) — for example, you can use a PWM controller or voltage adjuster to lower RPM. Do not exceed the rated voltage or current, as this degrades performance and lifespan. Avoid stalling the motor or running it under overload for extended periods, which can burn it out.

What are the recommended storage and operating conditions?

• Storage Temperature: 0°C to 40°C
• Storage Humidity: 15% to 90% RH
• Operating Temperature: 0°C to 70°C
• Avoid exposure to high temperature, high humidity, or corrosive gases during storage.

Common questions about this gear motor

Can I use this motor for a robotic arm?

Yes, this motor is suitable for small robotic arms, pan-tilt mechanisms, and similar projects requiring moderate torque and precise speed control. However, its 2.2 Kg·cm torque is best for light to medium loads.

Does the motor come with mounting screws?

No, mounting screws (M3) are not included. You need to supply your own.

What happens if I reverse the polarity?

Reversing the red and black wires makes the motor spin in the opposite direction. This is safe as long as voltage and current remain within specs.

Can I run this motor at 24V?

No, the rated voltage is 12V. Applying 24V will damage the motor. Use only within the specified voltage range.
