MFA 4.5-15V Large 5:1 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 5:1
• Rotations per minute of up to 2800
• Creates torque up to 314gf.cmWhat rotary speed can this motor gearbox do?
This 5:1 ratio planetary gearbox can produce up to 2800 rotations per minute and a torque of up to 314 gf.cm (gram-force cm) at maximum efficiency (12V). The motor operates between 1.5 and 15 volts and can change direction by reversing the input polarity. Weighing 167g and 64.3mm (81.3mm including shaft) long x 32mm in diameter this is a great addition to your project.
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.
