FK-180SH Micro Motor 20x32mm - 3-12V, up to 20,000 RPM

A compact brushed DC motor designed for RC cars, mini smart cars, nail grinders, clip-on fans and similar small devices. Runs on 3V to 12V, with speed scaling from around 4,800 RPM at the low end to 20,000 RPM at maximum voltage.

Key features

• Voltage range DC 3.0V – 12V, so compatible with battery packs from single cells to multi-cell arrangements
• Speed varies with voltage: 4,800 RPM at 3V, rising to 20,000 RPM at 12V
• Compact size at 20x32mm, weighing just 31.4g
• Current draw ranges from around 102mA to 138mA depending on voltage and load
• Speed figures are no-load; actual speed drops and current rises significantly under mechanical load
• Running continuously at maximum voltage will cause the motor to run hot and reduce brush lifespan

Ideal for hobby projects, toy vehicles, small appliances and any application needing a variable-speed micro motor.
