Product Description (Detailed):
Unleash robust power for your robotics and automation projects with our 150 RPM 12V DC Geared Motor with Centre Shaft. Engineered for demanding applications, this high torque metal gear motor provides exceptional rotational force at a controlled speed, making it ideal for moving heavy loads or ensuring precise movements. The integrated metal gearbox significantly multiplies the motor's inherent torque, allowing a relatively small 12V DC motor to deliver substantial power, typically in the range of 4.7 kg-cm to 32 kg-cm stall torque (values vary by specific model and manufacturer, always check product datasheet for exact specifications). The robust metal gears ensure superior durability and extended operational life compared to plastic alternatives, providing reliable performance in continuous duty cycles. Featuring a convenient centre shaft design, often with an internal threading or flat/D-cut profile, this motor offers straightforward integration with wheels, couplings, and mechanical assemblies. Operating smoothly across a voltage range, it delivers its rated 150 RPM at 12V DC, while speed can be modulated using PWM signals with compatible motor drivers like the L298N. Perfect for DIY robot platforms, automated systems, conveyor belts, and other high-torque applications where precision and reliability are paramount.
The 150 RPM 12V DC Geared Motor is engineered to provide reliable performance with moderate speed and strong torque, making it ideal for DIY robots, automation projects, motorized carts, and motion control applications.
Its all-metal gear train ensures durability and efficient power transfer, while the 6mm D-shaped shaft offers easy integration with wheels, pulleys, or couplings. Compatible with L298N, L293D, and other popular motor drivers, this motor works seamlessly with Arduino and other microcontrollers for controlled operation.
Whether you're a hobbyist or building a professional prototype, this motor delivers consistent power and quiet performance.
