Hello,

I have a bldc motor with windings in a (Star Y/ Delta D ) connection and i'm trying to drive it using the TLE9879 EVAL KIT.
For SW i'm using the BLDC FOC sensorless exemple. As i know this example is made for motors with windings in Star "Y" connection
The SW is working well with other BLDC motors with Start"Y" configuration but not with my motor with windings in Delta "D" connection"
Could you please tell me if it is possible to modify the code to adapt it in order to Drive this type of motors ? If yes which part i have to modify ?

Thanks in advance for your support

Hi M_BENDR,
please double check how to transform your motor parameters: https://en.wikipedia.org/wiki/Y-%CE%94_transform
After calculating you can adapt your settings with the "Config Wizard" - FOC Motor Parameter:
