I discovered that my area of riding has too many hills for the 6355 190kv motors on my TB All terrain kit (66/15 gears, 12s4p battery). On flats, I’m fine, and the power climbs smoothly. On hills, I feel like it’s working harder than it needs to be. Insult to injury…I have to run sensorless, because one of my motors isn’t detecting the hall sensors in the hall sensor tabling window. Tried for hours and troubleshooted the heck out of it.
Solution: New motors! Have to choose between the 6374 190kv and 6380 170kv. The price difference isn’t a problem to me, but I’m wondering about the schematics of both. Running 50amps on the 4.12 TB vescs. For my hilly area, I don’t want to undershoot it with the 6374.
Your bigger problem is the 50A esc. Before upgrading the motors I would upgrade to some sort of veac 6 that can handle more current. I have the same exact set up as you, and at 80A I can climb and accelerate up any hill. And i live in a very hilly area. Also I prefer 14 tooth pulleys on that set up. Much better torgue.
I used to run them at 60-65 per recommendation on the tutorial page on the website, and they’d last about 1-2 years of heavy riding. I only recently started running them lower.
Depends on your budget and how long you are willing to wait
Official Vesc 6
Unity
Dual focboxes
Wait for TB 6xx variant
Wait for Neo box
Maker X vesc 6 variant
I would steer away from flipsky but any of the above are good choices. If you need something soon I would try to buy a unity from someone on the forum
Also I’m gonna do Frank a solid here. Only the Trampa is a VESC, please don’t refer to anything else as a VESC, especially when you’re discussing the short comings of the non-VESCs.
Motors will generally produce more torque as long as you feed them more amps. until they saturate. Bigger motors run cooler but also have a higher flux density limit (saturation threshold). But usually you’ll cook something else before you hit saturation. Bottlenecks tend to exist elsewhere in general
6374 was the absolute standard around here long before people started slapping trash can size motors on the backs of their boards and no one had any issues climbing hills. I was climbing hills on 6355’s and I’m over 100kg on a good day with no clothes or gear - generally how I ride.
My 6355 and 50amps were no issue when I was riding a regular electric skateboard with urethane, not pneumatics. That thing flew up hills like no ones’ business.
I guess my ESC is the issue, but I need more information on how to adjust to that. What’s the most budget friendly option? How will I adjust to the differences in wiring-end sizes? I’m starting to find it annoying as hell that every option I’m seeing is a different size…I want to get it in the mail, hook it up to my computer, and hit the road. TB is all I use due to the instant easy plug and play with their 5mm wires being universal to their products. Idk how long the wait will be on their higher amp vesc6 variant.
Until now there is no budget ESC that could push high amps to big motors…If you can not afford that, a cheaper solution is to lower your motor kv choice (130kv to 150kv) and change your motor pulley for a 13 or 14 teeth…This will for sure make a diference. But at the end of your journy, you will realize that a great ESC it is a must to use the 12s4p at its best…
