Potting motor 6384

I’ve been following this forum for a couple of years and learning every day from everything you write.
My name is Gonzalo and I live in southern Spain. I’m currently very happy with my home assist.

I’m here to summarize my latest potting, as the previous two didn’t work well.
-First 6384 motor with generic epoxy potting, which was a mistake as it does not dissipate heat well and burned out after 8 sessions.
-Second 6384 motor with Electrolube thermal epoxy potting, which worked very well. However, I made a mistake when sealing the cables about 20 cm from the motor. I didn’t seal the heat shrink tubing properly and water ended up getting into the cable, causing one of the motor phases to fail after 4 months.
-Third motor (photos attached) 6384 Electrolube thermal epoxy potting. This time, I made sure that the cables were embedded inside the motor and at the other end in a Teflon machined connector.

I don’t have a 3D printer, so I machine my molds on a CNC machine, which is a good machine.
I hope you like the process.

Which electrolube are you using as a matter of interest?

Electrolube ER2183, 250 gr

Datasheet of ER2183 indicates viscosity 5000. It is very high viscosity for the application. It probably didn’t penetrate inside.

When you mix resin and catalyst, the viscosity drops significantly and it becomes more liquid. I recommend pouring quickly.
