<p><P>PROBLEM TO BE SOLVED: To suppress deviation of a permanent magnet 1 in the horizontal direction and the vertical direction due to self-weight and magnetic attraction force of the permanent magnet 1 itself to prevent loss and deterioration of efficiency due to magnetic flux disturbance in fixation of the permanent magnet 1 to a laminate electromagnetic steel sheet 3 in a surface magnet type permanent magnet motor. <P>SOLUTION: A permanent magnet 1 is fixed to a laminate electromagnetic steel sheet 3 with a permanent magnet holding member 5 having: a flange 5b which contacts the laminate electromagnetic steel sheet 3 with length of approximately the same dimension as width of the permanent magnet 1; a flange 5a which contacts the permanent magnet 1; and an opening 5c whose cross sectional shape is approximately in the H-shape, with the length of approximately the same dimension as the length of the permanent magnet 1, and is constituted so as to be clipped except the edge (bridge part 5e) of a thin sheet part which is sandwiched between the permanent magnet 1 and the laminate electromagnetic steel sheet 3. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
