PROBLEM TO BE SOLVED: To provide a control device for a full-pitch winding SR motor whose harmonic iron loss and noise can be suitably reduced.SOLUTION: A control device 30 for controlling a full-pitch concentrated winding switched reluctance motor by using a power conversion circuit 20 has voltage setting means 30b for setting instruction voltages Vu(&thetas;),Vv(&thetas;),Vw(&thetas;) of respective windings 22u, 22v, 22w equipped to the motor, and voltage control means 30c for controlling voltages applied to the respective windings 22u, 22v, 22w to the instruction voltages Vu(&thetas;),Vv(&thetas;),Vw(&thetas;) by operating the power conversion circuit 20. The instruction voltages Vu(&thetas;),Vv(&thetas;),Vw(&thetas;) have a first section which contains a gradually varying period and in which a positive voltage is applied, a second section which is continuously connected to the first section in which a voltage different from that of the first section is applied, and a third section which is continuously connected to the second section and contains a gradually varying period and in which a negative voltage is applied.SELECTED DRAWING: Figure 1 |
