keling drivers?

[j king]

Anyone running these? I was looking at new steppers and saw they had their own.I suppose I should stay with geckos but was curious.

[John Stevenson]

Yes, fitted loads and had no problems with them.
They are made by Leadshine in China and do have more protection on them than Gecko's.
Where they score is on the larger 7.8 amp drives driving large motors.
the Gecko have problems with large 42 series motors in that the resistance is very low on some of these that a Gecko see's it as a short on startup and blows. The Leadshine doesn't have this problem.

I have just bought 4 of the large drives this week for a Bridgeport conversion and 3 of the smaller ones for a router conversion.

My own router also has the smaller drives fitted and all the X3 CNC kits we have sold has been supplied with either 3 or 4 drives depending on whether the 4th axis is fitted or not.

None have been returned as faulty or damaged in use.
I have blown one up but we won't talk about that

John,

What model are you putting on the BP? I am going to put the 906 oz steppers on my boss conversion.I looked at their site and cant understand what the differences are.Very confusing. Geckos seem to have a basic,better,protected, and idiot proof! I guess I need the latter. : ) I may call keling Monday but I am sooo stupid at electronics that I will embarrass myself.
Thanks, jim

I bought some for my boss retrofit on John's recomendation, they have performed flawlessly.

Hi Jason.
What model did you buy?

Top one on the list KL-9082

These are actually better than the previous stock they used to carry.
Old stock was 80 volts max and 7.8 amps.
these are 90 volts max and 8.2 amp.

cool - Thanks sir John. : )

Well, since I have that decided on..whewww..Ill ask another question if you dont mind.

Dont really know what I need here as far as a power supply. Jim Glass gave me instructions on building one but I am not really much at building electrical pieces.I feel ok installing components if that makes any sense.

Back to the power. I take it you can apply as many volts to a dc motor as long as the drive will handle it.Well ,within reason.Is this correct? More power is always better as Tim Allen always says! Sorry dont know how to grunt on the key board.The extra power comes at a premium tho.

Or is the volts not as important as the watts available? Thanks again Jim

[John Stevenson]

Jim,
Power supplies are easy they are literally so crude. Give me a web site of someone you deal with as regards electronics, Mouser ? Digikey ? and I'll get some part numbers for you and a circuit.

What amperage are your motors ?

[j king]

John.

heck I am not dealing with anyone. I'm as green as a granny apple..

Here is the stepper I will buy. http://www.kelinginc.net/KL34H295-43-8B.pdf

These are the 906 oz steppers I had shown the other day. Rated Current: 6.1A, Rated Voltage: 2.1V (in Bipolar Parallel)

I was kinda figuring on ordering everything from Keling.It really doesnt matter tho.Kinda going by your positive recommendation of them.
