    Good Afternoon to all XSimulators!

    Can anyone advise me on the utilisation of 350W motors (I am going to be using the bridged Moto Monsters) or would I need to use another driver?

    Any help would be greatly appreciated.

    I am about to order the motors but I am going for 50 / 60:1 ratio @ 72 rpm with some motors that I have sourced. I am looking to bulletproof this simulator so thinking ahead before the actual build...

    Regards
    Ram

    Can you provide a link to the full specs of the motors @kanuk.

    Its a custom sir. I am getting them made with an industrial grade gearbox... Let me see what I can embed here.....

    Hi @kanuk did I understood correctly that you own the gears already and now you are looking for any motors?

    @Pit

    I ma acquiring the motors together with the gearboxes Pit. I have the option of going with a 350W motor. would the bridged Moto Monster boards handle it? Or would I need to look at a completely different motor driver?

    Regards

    @kanuk The max. of Watt says nothing about the needed torque. Or in other words: my 700W winches need only 30A current, because the weight of the seat (and driver) is the factor of needed current. On the other hand I bought a 200W motor for traction loss from ebay, this motor burned a 25A fuse while overturning due to a handling mistake. IMO 200W is enough, unless you are very fat ;) . Your motors have a output speed of 72rpm, in this case your lever can be relatively short, so the needed torque should be no problem at all.

    PS: sorry for the bad English, sometime I am very busy and than I am writing scrappy things...

    @Pit

    At 120kg's some will argue that I am 'very' fat! LOL :D
    Jokes aside I'm a large framed lad with a solid build (ex rugby player) and I want to be sure of the motors ability to move me without question. I totally understand that current consumption is directly proportional to load. And you have confirmed that those motors will do so I am happy! I will proceed to order those and give them a go.
    thank you so much for your help!

    Regards

    @kanuk , wow ex rugby player, impressive! :) Did you read rightly, I said "IMO 200W is enough, unless you are very fat"...I never thought, that you are fat, sorry for that, but 120 KG is heavy, in deed. So the 2oo Wat could be an issue. So please buy the 350 Watt motors and the sabertooth 2x60, the MMs will not handle (very fast turns) such a weight without any spring helper.

    ..or he is using linear springs. I am not a fan of springs, but using the right design it can work. If the load on the spring increases, the spring compresses an amount directly proportional to that load. Before I fiddled out how the MMS work as a half bridge (my winches need a big amount of current) I tried out some springs, and I can say it works not bad at all.

    @eaorobbie

    Thank you for that information. I am going to look at it with fervour and probably build a couple of units. I also know there is another type of bridge out there for high current applications. The name escapes me.....

    120kg? use a rear shoulder mount motor setup. Ive had 135kg on my previous DC motor shoulder mount seat mover.
    12v 200 watt motors. I had 25:1 boxes on them. Id suggest 50:1, 60:1 boxes on them though with your size.
    200 watt motors will move you fine as long as you place the motors right.

    @bsft

    Perfect. Thanks for the clarification chief! I am indeed utilising 50:1 boxes with the motor turning over 72rpms @ 52nm. So I am quite sure that will be functional like it should be.

    ;)

    @kanuk

    I see in your build thread you went for the motors from Motion Dynamics in Aus.

    May I ask how much you were quoted for the industrial gearboxes + 350w motors? and which manufacturer?

    Thank you!

    @Bobsyouruncle187

    Hello :)
    I have sought out those gearboxes through an old acquaintance of mine from China who is involved in the AV industry and supplies word driven mounts for large screen TVs and he's the one who's got the motors sorted out for me. The costs were about 150 USD per motor& Gearbox but shipping is going to be a killer by the looks of it...something in the region of almost $250 by air.....!
    But I'll do it anyway cause I am already accumulating the bits for the next sim build which is going to be a dedicated seat shaker for racing.... If you are interested let me know and I'll find out to se if we can ship together. Honestly, I am more interested in the gearboxes than the motors. They will fit any motor we choose to use in the Motion Dynamics range and seem phenomenal in build quality!

    Hello, bsft.

    Jrk 12v12, peak output current 30Amp is correct? so, It is can't be continues use to 35Amp?(If there on a heatsink with cooling fan)

    Thanks.
