    How to configure the Rs and Ls para. for PMSM in Delta connection

    Hi, I'm using TLE9879 for FAN's sensorless FOC control.Howerver the motor is not Y connection method.
    It is Delta connection.
    I measure the Rs and Ls with the 2 connection point. The result is 2/3 the single phase Rs and Ls value.
    Should I just use this value, or I multiply 1.5 with the measurement value to get the real phase value for FOC control?
