The biggest challenge in building a DIY robot actuator is heat. Both the motor windings and the ESC generate heat constantly—and if you can't dissipate it quickly, long-duration operation becomes impossible.

In this design, I placed the ESC directly inside the stator windings, combining the two main heat sources. With active cooling and minimal metal parts, the system remains highly efficient.

In this video, I’ll walk you through the design concept, full build process, and performance testing.
