PROBLEM TO BE SOLVED: To stably generate the torque with accuracy without receiving any influence from the iron loss of a stator and, in addition, to achieve a high energy transfer efficiency under the presence of the iron loss of the stator. SOLUTION: An equivalent load current iL of a stator from which the influence of the core loss of the stator is eliminated is generated by using a load current generator 9 constructed based on a relation iL=i1 +R1 .i1 -ν1 )/Rc established among the voltage ν1 , current i1 , a copper loss resistor R1 , and an iron loss resistor Rc of the stator. The current i1 of the stator is indirectly or directly controlled by utilizing the load current iL of the stator. |
