MFA 1.5-12V Small 4:1 Single Ratio Planetary Gearbox
• Small motor with integral planetary (epicyclic) gearbox
• Great for heavy duty industrial use, hobbies and model applications
• Operating voltage between 1.5V and 12V
• Motor ratio of 4:1
• Up to 1800 rotations per minute
• Creates torque up to 20gf.cm
• Compact size to fit small sized projectsWhat size is this motor gearbox?
The compact motor with integrated planetary gearbox is designed to fit into projects where space is restricted. It is just 41.8mm (53.4mm including shaft) long x 15.5 mm diameter and weighing just 35g. The motor can run in either direction by reversing the polarity of the input DC 1.5-12 volt power supply. The motor can produce up to 20gf.cm (gram-force cm) of torque and 1800 rotations per minute with its 4:1 ratio gearbox.
Why use planetary motor gearbox?
Planetary gearbox can be half the size of a conventional gearbox and more efficient allowing smaller motors to be used for the same output. Planetary or epicyclic gearing involves one or more planet gears rotating around a sun gear and an outer ring, the planet gears are often mounted on a carrier that rotates relative to the sun gear.
The motor gearbox can be used in heavy duty industrial, hobby or model applications. This robust motor with integrated planetary gearbox uses sintered bronze bearings, and with its sleeved bearings the metal gearbox allows high torque transfers from the motor through the gear box. The built-in gearbox can increase your turning power (torque) at a reduced rotations per minute from the motor. The optimum ratio for this will depend on your project. Powered by a DC power supply, the motor gearbox outputs to a 3mm shaft to connect to your project. It is not recommended to run this motor gearbox at 1.5V.
