    摘要： Under a condition that rotor rotation speeds (ωes are equal, winding wire currents Id, Iq are equal, and winding wire inductances Ld, Lq are equal in first and second electric motors 1, 2, a magnet temperature anomaly detector 30 provided in a microcomputer 5 calculates a change ratio d(|Φml-Φmr - Φmr|)/dt of a magnetic flux difference between the first and second electric motors 1, 2 based on the difference Vql* - Vqr* between a q-axis voltage command value Vqr* corresponding to the first electric motor 1 and a q-axis voltage command value Vqr corresponding to the second electric motor 2, and then when the change ratio d(|Φml - Φmr|)/dt of the magnetic flux difference is more than a predetermined threshold Sh1, it is determined that a permanent magnet of at least any one of the electric motors 1, 2 has a temperature anomaly.

    摘要： contactless electric power supply device 100 to charge a battery 28 of a vehicle includes a power transmitting circuit 101 having a power transmitting coil 12 and a charging circuit 201 having a power receiving coil 22. An electric power is transmitted from power transmitting coil 12 to power receiving coil 22 in a contactless manner. When the vehicle approaches power supply device 100, a trial power supply in which a electric power transmission through a minute electric power is carried out is executed and a power transmission efficiency from power transmitting coil 12 to power receiving coil 22 is estimated on a basis of a current flowing through power transmitting circuit 101. From this power transmission efficiency, a determination of whether power receiving coil 22 falls in a range in which battery 28 is chargeable with respect to power transmitting coil 12 is made.
