At the time of the switch what are the advantages of one over the other.
No brushes to replace but you only do that once every 10 years.
Higher rapids on a brushless then but less velocity control at very low speeds from cogging. The control loops were so very different back then.
Today it is a new world but during the change both DC and AC brushless were kind of oversold on rapids not real work.
I'm just old, like the linearity of the old brush systems, do not have to put 2-4 notch filters in the deal and a handful of gain breaks.
Should I say I also love linears with all their problems but crazy huge go fast now.
Do you want brushless as a fad, cost of replacement parts, performance or cycle time?
One master thing counts and that is shipping parts out the door.
You make money on invoices, many do well with not the best machines so perhaps your worry is misplaced.
