I am working with a DJI 10033/48kV (42 poles, 4kW) motor from their large agricultural drones and a flipsky fsesc 75100 pro v2.0. I know this ESC doesn't have an excellent reputation but it's what I have for now. I've read that low kV motors are notoriously difficult to tune, however my application requires it.
I use the device in a small winch to pull back a rope. When the drum rotates outwards, I disable the output and brake the drum slightly. Then when the rotation stops, it automatically turns on the output and asks the motor for the value set by the cruise control. Then the ramping time does not work. The drum accelerates very suddenly. I would like it to reach max. power slowly here too. I configured it in Lisp.
Is there a simple solution for this?
Hello,
over the last two years, ive built a gokart with four individually driven BLDC escooter motors. the motors are stated 10S, 350w. im running them on 13S 500w ebay controllers.
i built a custom 48AH 14S15P battery, so the motors are already overvolted. im having trouble with the motors being stupidly loud and in general, i think it could be faster.
(it goes 30mph down a hill if it feels like it :/)
I am using a MY1020 motor with a Flipsky VESC controller in FOC mode for a mower project. I am new to all of this, so I assume my terms and basic understanding of VESC may be wrong. I have successfully set up VESC and ran the motor for hours under load. My only tweaks to the setup wizard settings were to increase the motor current and limit the ERPM. I run by setting the ERPM to a value I am happy with. All seems to work well enough, but I have a couple questions:
I have a Flipsky and I cannot find the proper settings for the Obarter D5 in the VESC tool. The wheel motors are 2500w each, from what I understand. The motor FOC I find in the wizard is for 400w. If I am reading this correctly.
Can somebody point me in the right direction so I don't blow anything up?
Hey guys
Hope all of you are doing well
I was looking into vesc-based Flipskey controllers to run my 72V 6kW PMSM.
Ok, so I just built a VESC 4.12 a few days ago. I've been trying to get it up and running with VESC Tool via USB.
Hi everyone!
Looking for some VESC tuning help, willing to pay for it as it is a product that I am selling.
I have an electric wheel barrow motor that i am using on a tugging device, essentially its pulling heavy loads at low speed. I want to use PID speed mode and set my ERPM limit at a walking pace cause i don't want it to be able to go any faster. When i am at 5k erpm and i try and push it faster it actively brakes to keep the motor at 5k erpm, however when i get up to 10k erpm and try and push it faster it allows me to push well past 10k erpm even when i let off the throttle completely. Then when it comes down below 10k erpm it will resume its braking.
I have 2x identical setups having the same problem:
2x Flipsky FSESC 75350 and 2x Flipsky 85165 200KV 8KW continuous 19KW peak BLDC motors running sensorless on 50V, FOC, Current control, 300A limit, 450A ABS Max.
This is a dual outboard boat setup.
Auto-detected FOC values on each:
Setup 1) R 6.4, L 7.59, LQ-LD 0.90, Flux Linkage 5.38, KP 0.0076, KI 6.36, Observer Gain 34.56.
Setup 2) R 6.8, L 7.66, LQ-LD 0.68, Flux Linkage 5.61, KP 0.0077, KI 6.75, Observer Gain 31.79.
