MFA 4.5-15V Large 100:1 Single Ratio Planetary Gearbox
• Large motor with integral planetary (epicyclic) gearbox
• Great for heavy duty industrial use, hobbies and model applications
• Operating voltage between 4.5V and 15V
• Output ratio of 100:1
• Rotations per minute of up to 141
• Creates torque up to 4704gf.cmWhat ratio is this motor gearbox?
The motor with its integrated 100:1 planetary gearbox can get up to 4704gf.cm (gram-force cm) ,the equivalent of 0.461Nm, at maximum efficiency (12V) with a rotary speed of 141 rotations per minute. The motor runs off a DC power supply between 1.5 and 145 volts and reversing the polarity of the input with charge the direction the motor spins in. 77.1mm long (94.1 mm including shaft) with a diameter of 32mm and weighing 214g, this is a great motor for modelling or industrial applications.
Why use planetary motor gearbox?
Planetary gearboxes 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. It has a five pole motor with sintered bronze bearings, and sleeved bearings on the metal gearbox, allowing high torque transfers from the motor through the gearbox. 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 6mm shaft to connect to your project.
