Hello,
I have following setup for the use in a e-foil board:
- Motor: Flipsky 65161 / 100kv
- Controller: Flipsky FSESC 75200
- Remote: Flipsky VX3
Unfortunately, I can not regulate the motor continuously, rather digital, on/off.
Finger carefully on the remote and ...
When the value of the "input deadband" (15%) is reached, the controller immediately delivers 95% duty and the motor reaches its maximum speed.
I think by now I have tried and changed every function and every button and every value in VESC Tool once.... no improvement.
Does anyone have an idea what the problem may be?
The problem occurs via UART as well as via PPM. Have I perhaps forgotten to connect a control line?
Many thanks,
Christian
ok, new insight: in the combination "ppm + duty cycle" I can control the engine to some extent.
Not clean and not smooth, but at least I can vary the speed.
But I prefer to control the motor via UART, because then I can see the information about power and temperature in the display of the remote.
Someone has an idea ?
Nobody? 😔
Hi,
Why dont you run it in current (->torque -> force) control type? That way the controller will keep it smooth, and will use the appropriate duty cycle as the speed changes.

Use current control. The power and speed can only be controlled when there is a load. Without load the motor will spin up to high RPM really quick, since you dont need a lot of Amps for high RPM if there is no load.
