GA12-N20 6V 1000RPM Micro DC Metal Gear Motor

GA12-N20 6V 1000RPM Micro DC Metal Gear Motor is a high-quality, miniature gear motor that offers a superb combination of high torque and controlled speed in a very compact package. This micro gear motor integrates a powerful DC motor with a precision metal gearbox, providing a robust reduction ratio that translates high rotational speed into usable low-speed torque. Therefore, engineers frequently select the GA12-N20 for designs requiring precise motion control in confined spaces. The 6V operating voltage makes it perfectly compatible with battery-powered applications and standard microcontroller logic power supplies.

Key Features:

• High Torque Output: The integrated metal gearbox significantly increases the output torque, allowing the motor to drive substantial loads despite its small size.
• Precision Metal Gearing: Features all-metal gears for enhanced durability, reduced wear, and reliable long-term performance compared to plastic alternatives.
• Optimized Speed: Delivers a balanced speed of 1000 RPM (No-Load) at 6V, which is ideal for precise robotic movements and speed-critical mechanisms.
• Micro Size (N20 Form Factor): Its small footprint (GA12) allows for easy integration into miniature models, complex mechanisms, and space-constrained devices.
• Low Voltage Operation: Operates efficiently at a nominal 6V DC, making it suitable for direct connection to microcontrollers and small battery packs.

Technical Specifications:

• Nominal Voltage: 6 V DC
• No-Load Speed: ≈ 1000 RPM ± 10%
• Gearbox Reduction Ratio: Manufacturer Specific (Commonly ≈ 1:10 to 1:20)
• No-Load Current: ≤ 50 mA
• Stall Torque: Typically ≥ 0.5 kg·cm (Varies based on specific reduction ratio)
• Output Shaft Diameter: 3.0 mm (D-Shaft profile for secure coupling)
• Operating Temperature Range: −10°C to +60°C

Mechanical Specifications:

• Motor Type: Brushed DC Motor (N20 size)
• Gearbox Material: Metal Alloy (High strength and wear resistance)
• Shaft Type: D-Shaft (Prevents slippage when attaching wheels or couplings)
• Construction: Fully enclosed motor and gearbox for dust protection and longevity.

Dimensions:

• Gearbox Diameter: 12.0 mm
• Motor Body Length (Excl. Shaft/Gearbox): ≈ 15.0 mm
• Gearbox Length: ≈ 9.0 mm (Varies with reduction ratio)
• Shaft Length (Extended): ≈ 10.0 mm
• Total Weight: ≈ 15 g (Extremely lightweight)

Pinout and Wiring:

• Motor Terminals: Two solder pads or leads are provided for power connection.
• Polarity: Applying positive voltage to one terminal and ground to the other determines the direction of rotation. Conversely, reversing the polarity reverses the direction.
• Control: You should use an H-bridge motor driver (like L298N or DRV8833) to control both speed (via PWM) and direction from a microcontroller.
