Product Description
The 3V 6900RPM Micro DC Motor is a compact, highly efficient electric motor designed for low-voltage, high-velocity hobby applications. Operating on a safe 3V DC power source, this miniature power unit achieves a stable rotational speed of 6,900 RPM, providing an optimal balance of speed and mechanical torque. Enclosed in a rugged, lightweight steel shell, it delivers smooth electrical performance with minimal current consumption, allowing it to run for extended periods on standard household batteries or small solar panels without overheating.
This micro motor features an industry-standard 130-series footprint with precise, well-balanced dimensions for straightforward project integration. The flat-sided cylindrical body measures 38mm (1.5″) in length and 20mm (0.79″) in width/height, allowing it to slip easily into tight enclosures or custom chassis. The output side features a precision-machined 2mm (0.08″) diameter shaft with a 6mm (0.24″) extension length, ensuring compatibility with a massive selection of aftermarket hobby gears, pulleys, wheels, and propellers. Outfitted with dual rear solder terminal loops for quick power connections, this reliable mini motor is the ultimate choice for STEM school science kits, remote-controlled (RC) models, custom cooling fans, and automated DIY toy projects.
Key Features
- Precise Miniature Blueprint: Pre-mapped dimensions (38mm x 20mm) ensure quick, hassle-free integration into compact custom chassis.
- Balanced 6,900 RPM Rotation: High-velocity output delivers the ideal rotational momentum required to spin propellers, gears, and wheels.
