This for DC brush motor controllers I do not know brushless motor it probably has this adjustment too.

You do lot with adjustment on board.
The torque / amps can adjust.
From as add more torque the motor slows
To as add more torque the speed increase hard stop spindle and will give a lot of torque.
On our lathes should adjustment so speed stays the same at any torque.

Years ago, I did a modification to my control board. To prevent swarf from getting to the board, I fastened a piece of clear plastic (the kind used on report covers) about an inch away from it with RTV silicone.? And I had already drilled these screened ventilation holes in the section of the cover next to the board.?

So after these two modifications, my board has been protected from both swarf and dust bunnies, but it still gets adequate ventilation.

While the driver transistors and their heat-sinks for PWM-style motor controllers dissipate relatively little power, they DO dissipate some.? Being covered with convection-preventing stuff (the infamous "dust bunnies") isn't good for their long-term longevity.
