Driving2 brushless motors on 1 esc, forget it.
Sensorless brushless motors use the ripple/back emf to "read" the position of the magnets compared to the windings and adjust the cycle to that.
Sensored ESC/Motor combinations are a lot more accurate in that reading process and can achive better startups due that.
But introducing 2 sets of magnets and winding not in sync.... That's a a recipy for disaster.
thought so, but well, would be a shame if it was possible somehow (maybe by synching both motors or stuff like that), povide a somewhat "easy" solution and i won't use it just because i didn't think someone could find a way to make things work i can't. that would be stupid.
Would it also be a problem if i would use two ESCs, two Motors, and one Pulley on either side?
Just found out i'll get a space just big enough for the ESC right next to my weapon motor in the front part that's now angled. So won't be a problem to do this on both sides.
While the NeuMotor looks great, it is specificated for much more than 5s, and honestly... getting my current motor/ESC-setup twice would be cheaper. But i bookmarked it, so it definitly is an option, and if not for this build maybe for a later one. Always could use flat, powerful motors, to find long ones is way less trouble.
Also, with only 5S i don't know if the kv isn't too low on that one, would maybe even need a smaller pulley on the weapon than on the motor to get a good speed.
Got on with the weapon design, did a spoked disc inspired a bit by Valkiri, i have to admit. Diameter 250mm, at 24mm thickness, with the outer ring as well as the spokes (four of them) being about 20mm wide (a bit more for the ring on the tooth and counterweight), coming in at about 3000g if made from Hardox.
That's looking quiet doable, also having no problem to get it fit into the rest of the build. Motor and pulley on one side of the disc in this version, the axis will stay static and only disc/pulley on it will rotate (allowing some big bushings). Static axis is put between two 10mm Ali bulkheads, supported from the outer sides by 2cm HDPE coming at about 43-45° at it (have to fine-tune there a bit, depending on the actual motor i will use this angle will change a bit).
Motor will also be mounted on the same bulkheads (on one side of them), the shaft going through the bulkhead and then the pulley on it. got about 3mm clearance between pulley and disc as well as pulley and bulkhead, just gonna need a longer weapon shaft, i fear. the original one is just 20mm long, and would only stick out 10mm from the bulkhead. not a good thing to mount a 14mm pulley on to, even less with the clearance. (and i'd have to figure out how to put the pulley on that, without making everything wider. maybe just put holes through the hole diameter of the pulley, make them threaded and bolt that thing on the flat part of the shaft.
Would that be possible, or again put too much stress on the Motor?
