1 New Sensorless Field-Oriented Control for Six Phase Induction Machines By Sathish Kumar.K.S Edited By Sarath S Nair

2 Introduction SPIM –Six phase Induction machine Sensorless vector control technique Reference Model Model of SPIM

3 SPIM Two three phase stator windings spatially shifted by 30 electrical degrees.

4 control technique Does not required flux and speed estimators It uses only different b/w stator current of the mathematical model and motor,then forces them to decay to zero Simpler and does not need high computation time

5 Model of SPIM The SPIM is a double-six-dimension system(six stator and six rotor) Decomposed into three double-two- dimension orthogonal subspaces, (α,β),(z1,z2),(o1,o2)

6 Contd.. y= electrical angle b/w the two three phase stator winding

7 Machine Model in (α,β)

8 Machine Model in (z1,z2),(o1,o2)

9 Indirect Vector Control of SPIM

10 Contd.. The mechanical equation is the following in which J is inertia coefficient,and

11 Induction motor and model

12 Block diagram of overall system

13 Conclusion A new sensorless vector control for six phase induction machines, without flux and speed estimations was studied.
