VESC runs only with 50% duty cycle

Hello,

my problem is that the motor doesn't provide the full power. The acceleration is weak and the duty cycle rises slowly up to 50% an then stay constant.

I'm running a Flipsky motor 80100/130KV with a FSESC 75200 with the firmware 6.02.

My settings are:

Motortype: FOC; Sensortype: Hall Sensor; Motor Current Max: ±200A, Absolute Max current 250A; rpm and wattage > 100000, all limits are set very high

There is no error code in the debug console.

 

Thanks for your help.

There are many reasons for the cause of your problem. Your input is not set up correctly, Max duty cycle too low, reaching max erpm, etc.

Thanks for the idea but unfortunately that is not the reason. I even tried to manipulate the values. I made the setup and then reduced the maximum values. The idea was that there is any loss.

I made the motor wizard several times. As standalone and with connected axle. Of course I updated the firmware.

Phase filtering was deactivated before running the motor wizard

I switched of an safety functions like BMS and set the values for max. current and max. voltage very high.
