The utility model is suitable for the technical field of a motor structure, and provides a stator iron core, a stator with the stator iron core, and a permanent magnet motor with the stator. The stator iron core comprises an iron core body with a central hole. The iron core body comprises a yoke part and multiple tooth parts which are arranged on the yoke part. The stator iron core also comprises a magnetic conductive convex stand which is installed on the tooth parts. The magnetic conductive convex stand comprises an external convex part which is convexly arranged on the tooth parts along the axial direction of the central hole. The magnetic conductive convex stand is additionally arranged on the tooth parts so that axial length of the stator iron core can be lengthened and the magnetic concentration effect of the permanent magnet motor is enhanced. Besides, reduction of axial length of the iron core body is facilitated and reduction of turn length of a stator winding is facilitated so that reduction of weig
