Features: This DC motor features large moment of force, low speed, and low noise. The gear motor is primarily designed to reduce speed in a series of gears, which in turn creates more moment of force. Applications: perfect for window opener, door opener, mini windlass etc. This motor is adopted of pure copper wire coil, with low heat and low loss. The motor is made of metal gear, wear-resisting, avoid tooth breaking, so with long serving life.
