Why You’ll Love This 12V Gear Motor

• Blazing-Fast Rotation: With a no-load speed of 35,000 RPM at 12 volts, you’ll enjoy ultra-rapid motion, rapid acceleration, and immediate response the moment you apply power.
  Benefit: Perfect for applications demanding quick actuation, high cutting speeds, or swift rotational dynamics—think small conveyor belts, mini drills, or speedy robot wheels.
• Integrated Gearbox for Torque Boost: The built-in multi-stage gearbox reduces speed to increase torque output dramatically.
  Benefit: Effortlessly drive heavier loads, climb inclines, and handle resistance without bogging down, making it ideal for motorized carts, electric scooters, and robotic arms.
• Precision Axle Hole Design: The gearbox output shaft features a precisely drilled axial hole that measures 0.12 inches in diameter, allowing you to insert and secure pins, wires, or sensor leads.
  Benefit: Simplifies assembly and customization—mount encoders, route wiring, or insert locking rods with ease for a clean, professional installation.
• Standard 550-Series Motor Form Factor: This motor houses a 550-size can, an industry favorite for its balance of power and compact dimensions (approximately 2.6 inches in length, 1.5 inches in diameter).
  Benefit: Fits directly into most off-the-shelf brackets, holders, and mounting clamps designed for 550 motors—no need for major design modifications.
• Robust Metal Gear Housing: Encased in hardened steel and brass gears, the gearbox resists wear and tear from daily use and intense torque demands.
  Benefit: Enjoy long-term reliability in harsh conditions—even if your creation faces vibrations, dust, or moderate moisture.
• Wide Voltage Tolerance: Optimized for a 12-volt supply but capable of handling voltages from 9V to 14V without compromising performance.
  Benefit: Integrate easily with battery packs, power adapters, or automotive electrical systems without risking motor burnout.
• Pre-Tested & Ready to Install: Each unit is factory-tested under load to verify RPM, torque output, and gearbox integrity.
  Benefit: Save time on quality checks—install it straight out of the box and get your project up and running faster.
• Compact & Lightweight: Weighing only 0.9 pounds and measuring just 4 inches from gearbox front to motor rear including terminals.
  Benefit: Ideal for space-constrained builds and applications where every ounce matters, such as aerial drones or mobile robots.

How This Gear Motor Elevates Your Project

Imagine building a compact electric scooter that accelerates smoothly from a standstill—or equipping a robot arm that lifts and places objects with precise torque control. This versatile 12V gear motor gives you the speed and power you need while keeping size and weight to a minimum. The integrated gearbox transforms high-speed motor output into controlled, high-torque motion, making tasks like lifting, driving wheels, or turning sprockets effortless.

Thanks to its precision axle hole, you can add custom sensors or locking pins without needing additional drilling. Streamline your wiring harness by running small gauge wires through the shaft and out the rear—keeping your design neat and reducing wear risk. And because it’s pre-tested, you gain confidence that each motor meets our rigorous quality standards.

Perfect Applications

• Hobby Robots: Wheeled drive systems, joint actuators, conveyor loops
• Electric Mini-Vehicles: Scooters, skateboards, Go-Kart prototypes
• DIY Power Tools: Mini drills, rotary sanders, cutting heads
• Automation & Prototyping: Small assembly machines, pick-and-place rigs
• Educational Kits: STEM projects, school robotics challenges, maker workshops

Installation Tips

• Secure Mounting: Use M3 or M4 screws on the gearbox faceplate to lock it firmly in place.
• Proper Shaft Alignment: Ensure the mating gear or pulley aligns perfectly with the output shaft bore to prevent lateral stress.
• Wire Management: Route your power leads through cable clips or spiral wrap to avoid interference with rotating parts.
• Voltage Control: Pair with a PWM speed controller for smooth acceleration and braking.
• Cooling Considerations: In high-load scenarios, add a small fan or heat sink to the motor can to prolong lifespan.
