    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    idk man ... i tryed 4 controllers with this motor before i changed to the external sensors i can try the other controller but you think it well solve the issue? for me it just feels like the motor is just too weak, and im kinda douting ill get any decent proformnce out of the 2 of them im...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    its the same controller ive been using since i installed the external sensors it worked better then this just before the over heating .. plus it should be a very good controller (sabvoton 72150)

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    it cooled down and now it developed a wired vibration and the current consumption is 12A, i asume its eather hurt or the sensor is off again(i tryed recalibrating and it didnt help) im looking in to alterntives, sadly the shiping price for the qs motors to my area is the same as the motor...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    its the 14 pole i played with the sensores and timing again and got it to spin pretty smoth(to a point i cant hear any issue) here is a vid of it with no load https://www.youtube.com/watch?v=nzlga0jgZ3g no load current is about 6.5A in my case too i atempted to change the timing abit from the...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    the KV is about 43 (im geting 3460 RPM at 80V) think i should play abit more with the sensor? maybe re-zero it? maybe i zeroed it using the wrong phase wired? the other phase wires i tried gave worse results (self learn well fail consistently) did you use an FOC controller like that sabvoton or...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    yes thats the gearing give or take .. should give about 60 KM/H top speed and have the power as if it was geared for 20 at low speeds isssue is the motor really heats up, i limited the rated current to 80 and the phase to 200 went for a drive and saw that it pulled around 60 amps flored, it felt...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    the total lowest gearing is really low, its 0.0777 at the gear box after the variator, the variator is about 1:3 i asume (not sure about this one) and the chain is 2.15 so its 0.0556 lowest ratio and 0.167 high ratio i kept the variator becuse it allowed me to get very low gearing and still...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    so i ended up finding 2 phases that seemed to give an ok result the motor spins kinda smoth, it has a bit of a jumpy top end but no miss fires so i took it for a test raied https://www.youtube.com/watch?v=zbXIT3yEgQI it was alot better then before, but still weak, and the motor got hot...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    update i went throw all the 6 combinations(plus on one phase wire and nimus on another and so on) all 6 gave poor results i basically zeroed the sensor, then did self learn with the controller (acouple of times.. changed some parmaters) then i compared the motor behaviour runing forword and...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    i took 3 power supplies that can do 5A and conected them up in peralel for 15A, now it holes position .. ill try later the 6 opthions the motor itself is fixed to a plate that can slide in order to tention the chain, so ill need to make some sort of an arm that is bolted to that plate and then...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    i dont have any markings on the phase wires, i guiss ill just try all 6 opthions the thing is im limited to the power of my power supply and it can only do 5A, and at that current i can easly move it by hand somtimes it even sets on a sligtly diffrent position, how acuret does it need to be...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    hey, thanks for the replay! its the same encoder you got its just shellless, the guy at rls told me i should go with that since itll be easyer to make a new enclosure for it then itll be to modify the original one regardless, i solved the hall erorr isuue, i soldred to the large pads (as the guy...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    i installed the encoder, as sugested in one of the posts you guys linked, and for some reason i get 0 voltage reading betwine the U V and W to the +5V (one should always be +5V) the sensor isnt working ... any ideas? i wired it currectly, and its about 0.5MM away from the magnit as the spec...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    i think what ill do is add an external encoder to the motor like what larsb did here: https://endless-sphere.com/forums/viewtopic.php?f=30&t=87305 its kinda tricky in my case since my motor is mounted to the shazy from one side only what i think ill do is ill add a bearing to the side that...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    so i did some testing and conected the halls to a scope and the resulting sqware wave is acturly ok what i did notice thou is that the motor spins faster cw then it does ccw, and it does that regardless of witch of them is considured reverse by the controller, after watching this vid ...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    wow, thank you for shedding light! do you think its posible to mount the hall sensors externally? make a 3d printed mount that is moveable and mount the sensots on the rotors outer skin? well the emf be strong enoth to swith the hall sensors on and off? or is there an encoder i can get for it...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    yea i figured that might be the issue, i left out some stuff i did alrady thou so both the motors were sent to the manufacturere (they were bougth second hand) one got rewound to a lower kv (and new hall sensors) , second got his hall sensors replaced (flowing the issues i had) so both the...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    i saw this table, before i got the svmc72150 i was trying to get this system to work with a cheap greentime branded controller (80 amps) and i tried to find the combination using this table, but it always brougth me to a combination that didnt work :cry: is there more tuning opthios on the...

    issues finding hall sensor combenations using svmc72150 and revolt 120 pro motor

    hello! i had been trying to get this controller to work with 2 motors i have of the same type ( revolt 120 pro) the issue is that i cant find a hall sensor wiring combination that results in a smooth operation of the motor i went according to the manual and used the hall test feature, half of...
