<p>PROBLEM TO BE SOLVED: To provide a technique for suppressing generation of an eddy current in a magnet by covering only a part of the magnet by an insulator while reducing consumption of an insulation material in a motor including a rotor core into which the magnet is inserted.SOLUTION: In a motor 2, a magnet 8 is inserted into a rotor core 5. In the magnet 8, the whole peripheries of both ends in a direction of an axis CL of the rotor core 5 out of side faces parallel with the axis CL direction are covered with insulation films 9. Both the ends of the magnet 8 are supported by the rotor core 5 through the insulation films 9. Further, a side face area of the magnet 8 between both ends covered with the insulation films 9 is not covered with an insulation film and the magnet 8 is non-contact with the rotor core 5.</p> |
