Question PSU keeps shutting off during rapid motor movement

Hi There,

Anyone had any luck with the diode trick?
I am running 2 windscreen wiper motors and can trip the PSU with either using rapid motions.

I have the exact PSU you have and am wondering if it will help. I do have a spare PSU but dont want to waste this one if it is not necessary.
I have checked the motors for grounding and they seem fine.

With a small battery in parallel with with PSU will not stop, the cables as short as possible and 4mm section or more

Thanks for your help @evolaco, I managed to obtain the right Diode and did the Diode trick which worked perfectly.

I had the same problem with my DD steering wheel, the engine shut off the PSU, solved with 0.5 Farad condenser for Car use.
BRAX intellicap condenser with automatic charge and discharge, connected near H bridge

A conventional capacitor when you stop the source keeps moving the motor?

no, the condenser must be connected in parallel to the terminals of the power supply unit.Attention! the device when charged with very high discharge currents. or use a condenser equipped with automatic head for start and shutdown, or use a 10-20ohm resistor to charge it at each power supply start. also an automated system with a 10 seconds timer and a 30 + 30A tip doping relay.

this is the device in the picture. without him in support, even my big 40A bench power supply goes into protection as soon as I turn the steering wheel abruptly. while with the connected condenser it turns on to the overload warning light but does not go into protection

Two 22000uf capacitors can be put in parallel directly? when turning off the source would they be able to move the motor?

it is possible the parallel of more capacitors, rather it improves the esr. 44,000 micro are not many, I think they are not able to run an engine for a small step

I have seen that he has mounted a steering wheel, also in drivingitalia I have seen him comment, have open thread of his steering wheel or could he teach it to me?

at the moment the steering wheel works but it is still, waiting to finish the 2dof dynamic. I built the steering wheel thanks to the info found on drivingitalia and manu79. you can read well and try.

hello I followed the guide you read on drivinigitalia. using only a different engine in an experimental way. now I'm focused on the dynamic station. if you follow the guide you can build a working dd steering wheel.

I want to use two dy6812 150w motors with a 20mm belt and a 6: 1 ratio, I think that I will have a lot of strength with smaller motors and I do not think I will lose details with such a resistant strap. I want to use the stm board and mmos software, I do not know how I should do it, is there any guide like that?

[QUOTE = "evolaco, post: 155762, membro: 18926"] Voglio usare due motori dy6812 da 150w con una cinghia da 20mm e un rapporto 6: 1, penso che avrò molta forza con motori più piccoli e lo faccio Non penso che perderò i dettagli con un cinturino così resistente. Voglio usare la scheda stm e il software mmos, non so come dovrei farlo, c'è qualche guida del genere? [/ QUOTE]
Ciao Evolaco.
se devo essere onesto, non lo so, o almeno non ho usato questo software e hardware, avendo iniziato direttamente con Arduino leonardo e firmware FFBwhell, trovandomi molto bene non ho esplorato altri sistemi. Sono sicuro che la funzione cerca in questo forum fiorente e competente troverai sicuramente qualcosa adatto al tuo scopo.
PS: con il riduttore che intendi fare avrai sicuramente un sacco di forza newton, sulla trasmissione delle informazioni ffb non è un DD ma non è un ciao ciao

Hi Evolaco.
if I have to be honest, I do not know, or at least I have not used this software and hardware, having started directly with Arduino leonardo and firmware FFBwhell, finding myself very well I have not explored other systems. I am sure that the function looks for in this thriving and competent forum you will surely find something suitable for your purpose.
PS: with the reducer you intend to do you will certainly have a lot of newton force, on the transmission of information ffb is not a DD but it is not a hello hello

I'm sorry, I'm cheating Google translate, I think I post in English but it translates.

Use a capacitor to disconnect when the current is in risk of shutting down the PSU.
Am I getting this right ?

By the way, does a relay work the same ? Also, during running, there is a lot of stall current. Disconnect the PSU and motor, will it make the motor not reponsive ?

the capacitor and as a very fast battery, compensates for the fast current transients that a pwm power supply can not handle. with a relay the soft charge systems of the condenser can be activated,
