A new energy hybrid Motor iron core

The utility model discloses an iron core of a new energy hybrid electric motor, which comprises a fixing ring. The front and rear parts of the fixing ring are welded with annular edge plates, and the annular edge plates and the fixing ring are combined to form the installation at the front and rear parts. A plurality of single iron core blocks are arranged in the installation groove along the circumferential direction, and the end of each single iron core block near the center of the circle is provided with a stator tooth portion, and the stator tooth portion is wound around There is a stator winding, one side end of each single iron core piece is provided with a semicircular combination slot, and the other side end of the corresponding single iron core piece is welded with a semicircular combination block. A multi-layer structure is arranged on the outer portion of the core piece away from the center of the circle, and a ring-shaped heat dissipation fin group is arranged in the mounting groove and in contact with the outer side of the entire circumference of the stator iron core structure. The overall design of the utility model is reasonable, the replacement of a single iron core piece is realized, and the stable connection of the entire circumference of the stator iron core structure is ensured.
