Hi,

I have been using F2812 in sensorless FOC control,has any one here know how to measure the megnitizing inductance,leakage inductance and other motor parameters for each phase in three phase induction motor?

I have asked the supplier but strange enough they refuse to offer these data to me.

I would be very grateful if you can offer me some documents ,links or forum on this.

By the way,can anyone recommend a motor current sensing IC from TI which provide digital output, like IR2175 from IR? I need to use opto coupler to feedback the two phase current to F2812

Thanks!
