<P>PROBLEM TO BE SOLVED: To provide a motor controller for precisely detect the interlinking magnetic flux of an armature. <P>SOLUTION: A processing unit receives a signal outputted from each of sensors such as a current sensor 250 to detect current passed between an inverter device 200 and an armature winding 111 of a motor generator 100, a temperature sensor 140 to detect a temperature of the armature winding 111 of the motor generator 100, and a magnetic pole position sensor 130 to detect a magnetic pole position in a magnetic field 120 of the motor generator 100, and, based upon information on the current, the temperature and rotation speed obtained from the sensor signal, the unit obtains a magnetic flux that interlinks with the armature winding 111 from a permanent magnet 121 provided in the magnetic field 120 of the motor generator 100. <P>COPYRIGHT: (C)2010,JPO&INPIT |
