About this product

Overview

Product overview

• 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 516:1
• Up to 25 rotations per minute
• Creates torque up to 12000gf.cm

What torque can this motor gearbox produce?

This 516:1 ratio planetary gearbox and motor can produce torque of up to 12000gf.cm (gram-force cm),the equivalent of 1.177Nm, at maximum efficiency (12V), and rotates 25 times per minute. At 83.5 mm (100.5 mm including shaft) long x 32mm in diameter this is a great motor gearbox combination for projects requiring a high torque. The motor can run in either direction by reversing the input voltage, and you can use a power supply of 1.5 to 15 volts.

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.

I want to couple this to a variable tuning capacitor to finely tune an aerial. How slowly would this turn on say 6v supply? Would it be possible to send me a data sheet on this item please. Many thanks.

516:1 MFA Heavy Duty Epicyclic Motor Gearbox. Code: N04BQ Is this motor rated for continuous running? MFA Panel Mounted Speed Regulator Module. Using this module to drive the above will it further reduce the speed of the motor (RPM)?
