This Gravity DC micro metal gear motor integrates a compact DC motor, metal gearbox, and onboard driver into a single unit, simplifying wiring and control for small robotic and automation projects. With a 30:1 gear reduction, it provides improved torque at low speed while supporting forward, reverse, and PWM speed control through a simple control interface. Its small size and low power consumption make it suitable for educational robotics, mobile platforms, and lightweight actuator systems.
Product Description
General Description
This Gravity DC micro metal gear motor combines a DC motor, metal gear reduction, and integrated driver circuit in a compact form factor. The built-in driver eliminates the need for an external motor controller, allowing direct control through simple logic or PWM signals.
The 30:1 metal gear reduction increases output torque while reducing speed, enabling smoother motion and better control compared with direct-drive micro DC motors. This motor is designed for lightweight motion systems where space, simplicity, and efficiency are key considerations.
