Hi Mariss ! May I ask how do you measure the losses ? Jorge L. ... De: geckodrive@yahoogroups.com [mailto:geckodrive@yahoogroups.com] Em nome de Mariss...
Certainly. 1) We use two large 1mH 7A rated ferrite core chokes to simulate a motor load on the drive. Being ferrite core, the losses are nearly entirely...
Mariss, I received my shipment of G540 drive assemblies yesterday. I like what you have done. I plan on installing it into a custom made case along with the ...
The data in the attached link says it all. http://www.geckodrive.com/upload/G540%20Heatsink%20Experiment.pdf That is why I use a fan in all the G540 cases that...

Sorry guys got some more questions. Ok so I will have a G540. I need to work out what power supply will I need I currently have a 24v 6a switchmode power...
I just received my G320 and reading through the installation notes it says to set the three trim pots as follows: Turn the GAIN trimpot fully off. The LIMIT...
CW is fully on, CCW is fully off. Just like a volume control on a radio.

Bob, Good aftrernoon! Marcus ran a comprehensive thermal test on the G540s last week. I took his report from our commercial website and uploaded it to the...
No, well barely maybe.:-) It would require a calorimeter. Much easier is to measure Watts dissipated, then size a heatsink for that dissipation. Heatsinks are...
Let me say that Dan is a gem in this community. Dan knows what he is doing and he does it right. How do I know? Simple; I never, ever get support calls from...
I see no problem. You might be surprised and find it moves fast enough at 24VDC. Supply voltage only affects rapids, it has no effect at low speeds. If it is ...
Good info. We already have a temp probe input on the Dual port board. We could probable put on the single port board as well. We could have it turn the fan...
Mariss I have a problem with your conclusion that the G540 needs to go into a ventilated box..... I agree that the G540 must not be in still air, but that does...
The PC that runs your sealed box is ventilated.:-) Have a control box with an inlet and exhaust vent. Put the ventilation fan on the exhaust side. Make it the...
If someone really wanted a sealed box, couldn't they heatsink both the inside and outside across a thermoelectric module (cold side inside, hot side out) and...
Devil's advocate here: Sure. Cool the living heck out of the 1 square inch. Make ice form if you like. Meanwhile someone said their box is 16" by 24". That's...
Mariss The PC that runs the control box is ventilated, but not because any of the internal component producers insisted on it. And it needs a lot of blow-gun...
Rather than a known heatsink directly attached to the drive, the normal method puts the product in an insulated box, then connect a length of alloy bar from...
Sealed heat exchangers for electronics usually involve a hole cut in the door and a folded alloy sheet fitted. This is enclosed in a duck so fans pump air on...
Filters tend to be ignored. You can tell the owner of the machine to maintain them but few actually do so. Either the filter gets blocked or it gets damaged....
Good thread ! I believe Gerald (And leslie N) refers to the fact that the very fine wood dust tends to get everywhere. Like when making 300 l of sawdust, all...
