Are you kidding ? You can’t damage the motor using a brush! Even if you put heavyweight disc stabilizer and mat on top you can’t damage DD motor. Your brush in NOTHING for this direct drive motor. Low torque or high torque - you can’t stop the motor with brush if you know how to use it right.
I have two LUX PD-444, this is the brush I use for ages and I never stop the platter when I use the brush. If you don’t have this brush - buy it (the label can be different). It will cost you $6-15. The best brush ever made!
You don’t need a felt brush that looks like a brick with flat edges (I’ve seen some), those are for sleaning records when they are not on a turntable.
Soft carbon-fiber brush is what you need.
