I am looking torque-speed graphics of 57BYGH56-401A.

I didn't find at the internet.

Which company produce this motor?
...

Low cost 3 axis controller and open source codes.

I used calculated note frequency for the feedrate value.

Listen my cnc music. Also X and Z axis dansing.

Hybrids not tested for very hard conditions. (100v 10A driver).
Normaly hybrid functions independent from driver voltage and motor current.
But i must give sample large power driver schematics for...

I add the driver schematics and two video link. But firefox cant open these video. (Before opening save these file)

Thanks.

Not yet. But i tried 3 card.

I used cellulosic varnish but I dont liked.

Three MCR1207 hybrids working on the pcb router.

PI controller not good choice for AC systems. Because PI controller and stepper motor are like this low pass filter. PI controller not problem for low frequency. PI controllers are usable if you...

I use MCR1207 hybrid for the unipolar stepper motors.

I want same as hybrid type product.
Professional seem importand for me.

Like this

Thank you Kreutz,

But I can not find this products in my country.

First two cards completed but now i have big problem.
I don't know how I can coat this circuit.

Any idea?

Pcbs finished.

Now I am looking cheap coating material for the hybrid circuit.

I use linear encoder at my milling machine. My machine doing 0.1 mm error by 5um encoder. (While aluminum machining)

Making unipolar microstepper driver now too simple.

What you want? How much amper, how much volts ? Which microstep number?

Don't worry by MCR1207 hybrid.

1) Design step.

Load the MCR.exe...

I am planning to make this type hybrid circuits. I want learn the name of coating material.

I add some photos.

Single card (single processor) = 3 servo controller + 1 Handwheel encoder input + indexer

You need extra 3 power card.

One power card = 4 MOS + 2 MOS driver + few component + pcb.

Real...

Encoders are original 5um linear type magnetic.
I take A and B signals from encoder connector. (Normaly this signals differansiyel type (AA' and BB') but I use only A and B)

Maximum steady state...

Yes, I will give some photo on next days.

Handwheel for manual control.

I = C * dv/dt

C = I * dt/ dv

DeltaV is a ripple voltage.

T 1/2 of period.

If you want to 1v ripple for 60Hz and 1A;

Glue driver, GD.

You need higher current mos driver if you drive parallel mos.
Else turn on and turn off time extend.

But frequency is importand. If switching frequency is low you can use common looking drivers.

I finished new single servo controller card for 3 DC brush motors.

Power supply no problem. We can use 2 secondery (middle point) transformator and only extra one big capacitor.

If we use 3 motor. We need 12 mos and 6 mos driver for the full bridge.

Half...

Servo motor usualy turns at high rpm and produce low torque. Therefore need reduction.

You can direct drive to screew if you find low rpm high power motor.

Full bridge driver need four MOS. Half bridge need only two MOS but this drivers need symetric voltage source and also MOS VDS voltage higher (min x2) then full bridge MOS.

All popular motor...

I want to make 800ppr incremental encoder.

Have you any idea?
