要約(日本語): This study was conducted to evaluate the magnetization performances of HTS bulk magnets for the interior permanent magnet motors (IPM motors). A demagnetized Nd-Fe-B permanent magnet was scanned in the strong magnetic field space just above the magnetic pole containing the HTS bulk magnet which generated the magnetic field 3.4 T. The sample magnet was subsequently found to be fully magnetized in the open space of the static magnetic fields. We retrieve IPM motor from the air-conditioner compressor of automobiles. Then, we examined and analyzed the magnetic field distributions when the magnetic poles were scanned to activate the magnet plates in the IPM rotor. By applying this kind of numerical analysis of the magnetization for the motor-rotors incorporated with rare-earth permanent magnets, we confirm it becomes possible for motors to give high degrees of freedom on their designing processes.
