N20 3V 600 RPM Micro-Gear DC Motor

Product Description The N20 Micro Gear Motor is a compact, lightweight powerhouse designed for precision robotics and miniature mechanical systems. It combines a small coreless DC motor with a high-quality full metal reduction gearbox to provide a perfect balance of speed and torque. The "D" shaped output shaft ensures that gears and wheels stay securely attached without slipping, making it the industry standard for micro-sumo robots, smart door locks, and DIY hobby projects where space is extremely limited.

Key Features

• Miniature form factor ideal for space-constrained electronics.

• All-metal gear construction for high wear resistance and durability.

• High-speed 600 RPM output for rapid movement and response.

• D-shaped output shaft for secure mechanical coupling.

• Low power consumption, suitable for battery-operated handheld devices.

Prototyping and Engineering Tips from Robogears

• Mounting: Use N20-specific mounting brackets (available at Robogears) to secure the motor. Avoid applying pressure directly to the gearbox casing, as this can misalign the internal gears.

• Voltage Flexibility: While rated for 3V, these motors can safely run at 6V for short bursts if you need double the speed, though this will increase wear on the brushes over time.

• Shaft Cleaning: Ensure the D-shaft is free of oil or debris before mounting wheels. If a wheel is loose, a tiny drop of thread-locker can be used, but be careful not to let it seep into the gearbox.

• Driver Choice: A tiny H-Bridge like the MX1508 or DRV8833 is perfect for controlling these motors. Since they draw low current, you can easily run two of them from a single small driver module.
