ABSTRACT:
Disclosed herein is an inner rotor type permanent magnet excited transverse flux motor, in which a laminated structure in an axial direction or in a radial shape is applied to a stator iron core so as to employ a small amount of permanent magnets compared with a conventional outer rotor type permanent magnet excited transverse flux motor, thus providing high output power, increasing the efficiency of power generation, and reducing noise and vibration. For this, the present invention provides an inner rotor type permanent magnetic excited transverse flux motor comprising: a stator including a stator powdered iron core press-molded using a mold, a stator laminated iron core laminated on upper and lower layer portions of the circumference of the stator powdered iron core at regular intervals, and a stator winding which winds the segmented stator powdered iron core in which a current flows is wound between the intervals; and a rotor in which a rotor permanent magnet and a rotor powdered iron core are arranged alternately to face each other.
