My brother just got his home built 3 axis CNC table built but he has one rather limiting problem. Stepper speed limit.
His top travel speed is only 15 inches a minute! The stepper motors he is using are these.
Vexta PK266-01A-C23
2 PH 1.8 /STEP
7.4 Volt 1 Amp
The control boards use TA8435H driver IC's
He has a power supply capapble of 0-40 volts at 15 amps so power is not a problem.
Everything moves smooth and works well but the motor RPM's just seem low. If they get over a specific speed they have problems.
Is there a way to get more RPM's out of them or will he just have to change the mechanical drive sytem?
I have seen stepper motors of this size and step ratio run at much higher RPM's before.
