This brushed JGA12-N30 DC micro gearmotor, which is a little longer than N20 motors.It is small ,so it is easily mountable and configurable. these small brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1, with precious metal brushes,It is perfect not just for robotics but also for battery-operated prototypes and a lot more.All of the micro metal gearmotors have the similar physical dimensions. This high torque full metal gear mini DC motor is perfect for hobbyists and students who want to do robotic projects such as Intelligent robot, intelligent manipulator, intelligent furniture,Intelligent focusing system, miniature head, etc as well as any rotating mechanical device.These gearmotors are also available with an optional extended motor shaft.

Some customers use the N30 dc gear motor working on a liquid nutriment dispenser.

The specification required of the liquid nutriment dispenser are the following:
-speed: 40-60rpm under load
-load torque: must be able to handle 2000gf.cm (the motor is used to drive a cam, the torque on the motor will oscillates between 200 and 2000gf.cm)
-voltage: 12V DC
-working time: the motors will be used for 25-50 rotations every day
-gearbox: spur gears, straight output shaft (no worm gear)
-shaft: 8-10mm length, 3-5mm diameter
-dimensions: smallest possible while respecting the other specifications

Benefiting from JGA12-N30 motor's high torque, compact size and weight, Which all the requirement above that the JGA12-N30 motor can meet.
