What is the highest voltage and amperage you can run on the original boards?
I know its ratings but I was wondering if anyone has tested the old one or has been running them at higher voltage and amperage outputs with no trouble. I have 3 of the 10A/60V boards that have run perfect for almost 2 years now but with only nema 23 size servos on them.
I would like to run a lathe spindle with one and was wondering if the Keling servos would work! (specs for one of them is below)
constant torque: 1.2 N.m ( 170 oz-in)
-peak torque: 6.0 N.m (850 oz-in)
-max. speed at voltage constant: 4200 rpm
-terminal voltage: 72 VDC
-continuous current: 8.8A
-peak current: 40 A
-torque constant (KT): 0.14 Nm/am
-voltage constant(KE): 15 V/100rpm
-resistance: 0.52 ohm
-inductance: 1.8 mh
-inertia: 3.39 kg/cm^2
They have a larger one but I am not sure it would work.
Constant Torque: 1.6 N-m ( 226 oz-in)
Peak Torque: 8.0 N-m ( 1125 oz-in)
Max Speed at Voltage Constant: 3200 RPM
Terminal Voltage: 90V
Constant Current: 7.8A
Keling Technology Inc
Peak Current: 40A
torque Constant (KT): 0.182 NM/am
Voltage Constant (KE) 18.95 V/rpm
Resistance: 0.925 ohm
Inductance: 2.5 mh
Inertia: 3.4 kg/cm^2
I would probably run it with a belt drive 2:1 ratio motor to spindle.
Any thoughts are much appreciated!
A HP-UHU kit would be the best for you. email uhu.highpower(at)gmail(dot)com
it would get you rid of all difficulties, however I have seen people on the German forum use the original design for motors upto 2KW, but not sure how stable they were or if stable what modifications were done.
