In the world of micro-robotics, precision equipment, and automated systems, power source selection is critical. Compact yet powerful motors with precise control capabilities are essential for achieving complex functionalities and high performance. Pololu's newly released 1000:1 Micro Metal Gearmotor HP 6V addresses these requirements with exceptional specifications and compact design, offering innovative solutions across multiple industries.
The Pololu 1000:1 Micro Metal Gearmotor HP 6V combines brushed DC motor technology with precision metal gearing. Its key advantages can be quantified through these specifications:
- Dimensions: The gearbox measures just 10 × 12 mm in cross-section, offering a 29% volume reduction compared to typical 12 × 14 mm alternatives.
- Output Shaft: Features a 3mm diameter D-shaped shaft with 9mm length, designed for optimal torque transmission and reduced slippage.
- Gear Ratio: The 986.41:1 reduction ratio enables significant torque multiplication while maintaining compact dimensions.
- Materials: Brass gear components enhance durability and corrosion resistance compared to plastic alternatives.
Key operational parameters reveal the motor's capabilities:
- Motor Type: High-power 6V variant with precious metal brushes for extended service life
- No-Load Speed: 31 RPM at 6V (100 mA current draw)
- Stall Torque: 12 kg·cm (theoretical maximum at 1.6A current)
- Peak Efficiency: 28% efficiency at 26 RPM with 2.0 kg·cm torque output
With total dimensions of 10 × 12 × 28.5 mm (excluding shaft) and weighing just 10.5 grams, the motor demonstrates a 32% volume reduction and 12.5% weight reduction compared to comparable alternatives. This miniaturization enables integration in space-constrained applications without compromising performance.
The motor's characteristics suit multiple advanced applications:
- Micro-Robotics: Precision joint and wheel actuation for sub-100g robotic platforms
- Automation Systems: Compact drive mechanisms for vending machines and precision instruments
- Medical Devices: Low-profile actuation for portable diagnostic equipment
- Model Engineering: High-torque solutions for RC vehicles and scale prototypes
Performance optimization requires attention to:
- Stall conditions generating 1.6A current should be minimized to prevent damage
- Voltage should remain within 6V specifications
- Load capacities must respect torque limitations
Industry trends indicate growing demand for micro-motors with:
- Higher power density within shrinking form factors
- Improved energy efficiency exceeding 30% thresholds
- Integrated position sensing capabilities
- Extended operational lifetimes through advanced materials
As technological advancements continue, such precision micro-drives will enable new generations of compact electromechanical systems across industrial and consumer applications.
