A brushless DC motor uses a VDF and 3 phase motor.
?
The best part of brushless type s is they very low maintenance and last long time.
The best part brush type is as motor slow down you get greater torque.?
?
When look graphs from a company there graphs are wild.
?
I have on some things brushless just not on my mini lathe and try find true graphs
?
?
Here a graph on AC motors very little different between single and three phase. Note the brushless use a 3 phase motor. FYI In computer a 2 phase is use so curve is flater I think.?
?
The graph shows the curve.?
Thd lower one is a schematic of brushless motors.?
?
Here torque chart of brush DC motor.
