Gearmotors are an all-in-one combination of an electric motor and gears or a gearbox. A gearmotor simplifies combining a motor with a gear reducer system. Gears are used with motors to lower the motor’s speed while increasing the output torque.With plastic construction and colored in bright yellow, the DC gear motor measures approx. 2.5 inch long, 0.85 inch wide and 0.7 inch thick . The wheel can be mounted on either side and the gearmotor works well between 4V to 7V (recommended 6 Volts). At a ratio of 1:48 you can get some really good torque at 5 Volts.
