@Mus84 the water will seep out of the motors slowly as long as there is a weep hole or someway for it to egress. Motors are full of dissimilar metals which when combined with water expedites the corrosion or oxidation process.
The front of the motors have holes for screws when mounting the motor. I’m using 2 holes and there are maybe 3-4 free. I have submerged the motors but when I will be using outdoors will some exposure to wet grass cause a major problem like rusting? It won’t be going into deep puddles or shallow water. Would all these precautions still need to be made for this?
The description on the website is as follows:
The 12V 100RPM 583 oz-in Brushed DC Motor with 100% pure copper coils, high-density molecular layer, 50:1 metal reducer, small size, large torque. The maximum torque could arrive 42 kg.cm, stable and durable!
It says pure copper coils. Does that mean this grease that I’ve used is suitable or could there still be nylon gears inside?
“50:1 metal reducer” also the gears are metal, the coils are the brushes from motors.
It is a low-cost engine, there are engines that have grffite brusches, they cost a little more.
However the grease you put does not reach the engine but only in the gerbox that is the cylindrical part where there is the motor shaft.

In terms of using that specific grease for the motor I have I’m safe?
I wonder about the parasitic power loss as well as extra friction that will be generated by filling the gearbox with grease? Normally you grease bearings and run oil on gears. I understand that a lot of small electric motors run dabs of grease on gears, but there’s a huge difference of having a dab of grease on a gear and filling a gear box with grease…
yes bmoscato, it is true, too much grease in the gears is not good, as you pointed out, the engine has a power loss.
in fact no one told him to fill the gearbox. however it is better too fat than too little,
and since the engine he used is not new, he probably did a good thing.
another fact is that fat and oil is hydroscopic which means that it absorbs water and increases friction.
