It is a simple DC Motor featuring metal gearbox for driving the shaft of the motor, so it is a mechanically commutated electric motor which is powered from DC supply. The Johnson Geared Motor are known for their compact size and massive torque-speed characteristic.
The Johnson Motor comes with side shaft also known as an off-centered shaft and six M3 mounting holes. The shaft of the motor equips metal bushes which makes these DC gear motors Shaft wear resistant. The shaft of the motor has a hole for better coupling.
The motor will run perfectly between the voltage range 6 to 18 V DC and give you 30 RPM at 12V supply. It provides the torque of 9.4 kg-cm at 30 RPM.
This gives very good torque at an affordable price hence they are widely applicable in Pan or Tilt camera, auto shutter, welding machines, water meter IC card, grill, oven, cleaning machine garbage disposers, household appliances, slot machines, money detector, automatic actuator, coffee machine, towel disposal, lighting coin refund devices, the peristaltic pump and so on.
Also, they are best suitable with highly developing capable robots or robotic platform, various automation purposes.
