FIRGELLI® Gear motors are DC powered with a reduction ratio gear head attached to the motor to increase power and decrease speed. A DC motor on its own is not particularly useful, which is why a Gearbox is required to slow the RPM down from what could be several thousand to a few hundred.  Each time the speed is gear ratio down, then the torque or power is increased substantially.  We offer a range of Gear motors for many different applications.
