OK, I`ll gave you more info about my project:
The goal is to move hydraulic actuator in very precise sloooooow short stroke=18mm.
The hydraulic system is small - RC hydraulic models in this way. But, I want to do some hybrid type, RC-in industrial way:) ...I need the stroke holding force around 1500kg in both directions, so I choose hydraulics and I need to control it.
so...BLDC-KV1000 - motor run the pump, I
ll run it manualy, I attempt to change rpms for the testing with potenciometer. The goal is to find right rpm
s from 7000-12000rpms "adjusting the pump flow" - for testing the system.
m want to test the fade IN/OUT for the stroke-I need to correct the HOLD position. I dont know jet majbe with rpm`s. Slower is more precise. Important info, but I must come to this point.
How slow/precise I want, I need to test.
The direction valve "HYDAC-WK06G-01" has two coils; 12V @0.98A each, to charge each coil, to move the stroke of the cylinder, one for forward and second for backward. I need manual mode and automatic mode for testing and simulate oil leaking so the actuator will lose the adjusted position. The automatic system will correct the position automatically.
The LED reed light will shine or alarm-beep will screaming with ERROR-lost position and oil leaking info on bigger LCD screen will shown up...this must be, becaus of this info I can recognize the broken piston seal.
I already prepared the test bench with AC/DC 400W [12V@33A power supply].
16x2 LCD or multiple of them 16x2 or one bigger LCD
3/4 directional valve with two coils
electronic hardwer components, have a lot of them and still waiting for them
...I`ll wrote here what I have
I already tested the LCD code, with LCD 16x2 and special potenciometer and works fine. I have info the position from 0-100[%], 18mm=100%
I already test the BLDC-motor code. I can adjust the motor rpm
s, If we look the scale on the potenciometer, the motor start spinning from 25% and at 60% has max.rpms. The code is simple, but I tried with 5Kohm, 100kohm potenciometer and is the same...I don`t know where is the problem.
I done a lot for now. I have done cca 50% of entire work for now, mechanicaly I done all in CAD
Now I realized that I need help because I`m not electric engineer, I know only basic fundamentals in this world.
I understand, I
m also rough, because in the beginning also I dont know how to inform you to explain. I will provide my hand drawings but remember this, I
m not electric engineer :confused: ! The hydraulic is simple in this case....pump+3/4valve+actuator, thats it.
Thank you for understanding.
