A controller for rotating electrical machines comprises a processing unit, to which a plurality of parameters are input, for generating a switching instruction to control a switching operation of a switching semiconductor device and outputting a signal corresponding to the switching instruction to a power converter. The processing unit includes at least a function to input thereto signals having been output from each of sensors such as a current sensor (250) to detect current passed between the power converter and a winding of an armature, a temperature sensor (140) to detect temperature of the winding of the armature, and a magnetic pole position sensor (130) to detect magnetic pole position of a magnetic field system, and, based upon information on current, temperature, and rotation speed of the rotating electrical machines, having been obtained from those sensor signals, detects a magnetic flux that interlinks with the winding (111) of the armature (110) from a permanent magnet (121). |
