Question
I have Ld,Lq values for IPMSM delta connection.These Ld,Lq values were taken from motor cad.But Motor cad could not provided Zero Sequence inductance(L0).So,I want to know how to calculate Zero sequence inductance(L0) for ipmsm delta connection.

The zero sequence inductance can be calculated using L0 = V0open/I?0short? where V0open? is the open-circuit voltage for the zero sequence and I0short? is the short-circuit current for the zero sequence.
- Open-Circuit Voltage for Zero Sequence: you'll need to perform a simulation or measurement under zero sequence conditions. You can apply a zero sequence voltage at the motor terminals while keeping the other phases open-circuited. Measure the resulting voltage across the motor terminals.
- Short-Circuit Current for Zero Sequence: Similarly, you'll need to simulate or measure the short-circuit current under zero sequence conditions. This involves applying a short circuit to the motor terminals while injecting a zero sequence current. Measure the resulting current.
