The invention discloses a designing method of segmentation of a permanent magnetic motor rotor. A stator and a rotor are arranged on a permanent magnetic motor. A stator punching sheet is installed on the stator. The mechanical angle alpha of each groove is firstly determined; then, the segment number of the rotor and the height h of each segment are determined; and the rotation angle beta in the same direction of each segment is calculated. The rotor comprises a rotor shaft and rotor punching sheets. The rotor punching sheet sleeves the rotor shaft and comprises a first protruding key, a second protruding key, a first magnetic pole central line and a second magnetic pole central line. The designing method of four segments of rotor punching sheets sharing one punching sheet comprises steps of 1) designing a first segment rotor punching sheet specific structure; 2) segmenting the rotor punching sheet in the first sequence; 3) carrying out specific superposition; 4) designing a specific structure of the rotor s
