For some months now I’ve bin building an efoil board. Some weeks ago, it was on the water for the first time – great. But the motor power is low, and it’s difficult to get the board out of the water. According to the remote, with telemetry, the motor delivers up to 1600W. (after 30 seconds power fades to below 1000W) It should be more than 4000W!
So I hope to get some help about the installation.
Motor: Flipsky Waterproof Brushless DC 6384 Motor 140KV 4400W
ESC: Flipsky FSESC6.9 100A base on VESC6.6
Remote: Flipsky Remote VX3, connected via UART.
Battery: 2 X 6 cells, 7000mAh LiPo in series
I guess the problem is in the vesc settings, so here it comes:
Current limit is set too low. Set motor current at 150A, abs max current at 200A and battery current to what your battery can deliver.
Which prop do you use? If it’s too large you won’t get the power needed, might be worth checking which duty cycle you reach with full throttle in water
Thankyou I will try to set motor current to 150A and Max at 200A. (The motor specification says ‘Rated current’ 59A and ‘Max current’ 88A. How does this relate?)
The reading in the remote is around 33A at full throttle!
The prop is Flipsky 4.8" Foldable that is sold as a set with the motor. Its a little difficult to get logs from the VESC since its not possible to connect with bluetooht. Maybe I have to setup i a harbor with a PC.
I set the motor current to 115A and battery max current to 150A. (The VESC is rated to 100A continuous and the motor to 59A, so I was a bit worried). I also changed the motor type to FOC and re-detected parameters.
The result was amazing: I could reach more than 3000W. The board could get up foiling with no problem. Even heating seemed less than before. (The remote also has an ampere reading but I forgot to notice)
Thank you for all the advice.
