MFA 1.5-12V Small 62:1 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
• Output ratio of 62:1
• Up to 119 rotations per minute
• Creates torque up to 227gf.cm
• Compact size to fit small sized projectsWhat ratio is this motor gearbox?
This compact motor and integrated 62:1 ratio planetary gearbox can deliver up to 119 rotations per minute and torque up to 227gf.cm (gram-force cm), the . At just 49mm long (60.6mm including shaft) and a diameter of 15.5mm and weighing 42g, this is a great addition to many small or enclosed projects. The motor can be use in a clockwise or anticlockwise direction dependant on the polarity of the incoming voltage. Operating power should be DC 1.5-12 volts.
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.
