Hey all after blowing my leadshine drivers (my fault)
Ive finally save up for the gecko g203v's
and the Pdmx motherboard for them along with the Pdmx 26
4x geckos cost me £567 from charter controls
Pdmx boards cost like £200 posted from us
now here's my next problem
my power supply
motors are rated at 3.78v
current is 4.2a/phase
inductance is 3.8mh/phase
any recommendations for a psu to drive 4 motors ?
Thanks in advance
Have you bought the Gecko drives, if not why not stick with Leadshine drives (are you sure you have blown them up).
Re the power supply the Gecko drive with take up to 80V but I would keep it down to around 70V. Something like http://www.zappautomation.co.uk/elec...er-supply.html or find one with a little more amps .
Have you got two motors on one of the axis if so will the Pdmx board support slaving?..Clive
I couldn't fault the leadshines to be fair I just thought I'd get the geckos as there is so much info on them so I now have 4
the leadshine may come in handy for another project, just wanna get the plasma working
the Psu from zapp only has 3 outputs
yes I have two motors on 1 axis and yes I'm sure the pdmx supports slaving
doing some research and it looks like for these motors 62v is the right Psu
is this correct?
I found this calculation online saying
take the square root of the motor inductance which is 3.8mh
times it by 32 and this is the voltage
is this the wrong way to calculate?
thanks again for the help
the pmdx 126 can only be slaved if used with pmdx 134 I think
I don't see in the manual re the 134 slaving it just looks like a breakout board for the gecko...Clive
Gecko cover it in the power supply section of their stepper motor basics guide - http://www.geckodrive.com/support.htmlAvoiding the rubbish customer service from AluminiumWarehouse since July '13.
So 60v - 62v would be the correct size psu? If I use 68v I assume I would have unwanted motor heat?
is anyone in the north west able to make a psu for me for a fee
cant find enough info to buy the parts and build myself
would like a linear psu to minimize electrical noise
Also what amp psu would be sufficient
