CHANCS N20 Micro DC Motor 3.7V 23500RPM 2-Pack for Gear Motors, Toys, and Science Projects
CHANCS N20 Micro DC Motor 3.7V 23500RPM 2-Pack for Gear Motors, Toys, and Science Projects
These CHANCS N20 micro DC motors run on 3.7 volts and spin at 23,500 RPM. Each measures 15.5 by 10 by 12 millimeters with a 1.0 mm shaft diameter and 8.5 mm shaft length. The package includes two motors, making them a convenient option for small gear motors, solar-powered toys, digital gadgets, and electronic door locks.
What makes the CHANCS N20 micro DC motor suitable for small projects?
The double-ring construction uses precious metal brushes and a strong magnetic field to deliver consistent performance in a compact frame. At just 15.5 mm long and 10 mm wide, it fits into tight spaces where standard motors won't go. The 1.0 mm shaft works with many small gears, pulleys, and propellers found in hobbyist and educational kits.

How are these motors typically used?
Their small size and moderate torque make them a frequent choice for DIY gear motor assemblies. Hobbyists put them in solar-powered toys that need a lightweight drive, while experimenters use them in science fair projects that require a reliable miniature motor. Digital products like mini fans and electronic door locks also rely on this form factor. Pair one with a small gearbox to create a low-speed high-torque drive for a robot, or attach a tiny propeller to build a mini USB fan.
Common questions about the CHANCS N20 motor set
What voltage range can these motors handle?
The specified working voltage is 3.7 V DC. The supplied data does not indicate a range, so it is best to operate them at or near 3.7 V for the intended speed.
How fast do they spin under load?
The 23,500 RPM figure is the no-load speed. Actual speed under load will be lower, depending on the torque requirement of your application.
Can these motors be used in reverse polarity?
DC motors change direction when polarity is reversed. The supplied information does not mention any restrictions, so reverse operation should be possible, but always test within your circuit.
What is the intended lifespan?
The brushed design and precious metal contacts support a reasonable service life in intermittent use, but the manufacturer does not provide a specific hour rating in the supplied data.
What comes in the package?
You receive two CHANCS N20 micro DC motors. No mounting brackets, wires, or connectors are included.
