MOTOR IRON CORE

The present invention relates to the field of motors. Disclosed is a motor iron core, comprising first material sections and second material sections. The first material sections and the second material sections are stacked in a height direction; each first material section comprises a plurality of connected pieces, the plurality of connected pieces are stacked in the height direction, each connected piece comprises a plurality of tooth pieces, and the plurality of tooth pieces are fixedly connected to each other; each second material section comprises a plurality of loose pieces, the plurality of loose pieces are stacked in the height direction, each loose piece comprises a plurality of tooth pieces, and a gap is formed between every two adjacent tooth pieces. By means of the design, when the height of the motor iron core needs to be changed, there is only a need to adjust the number of loose pieces, so that the height of the motor iron core can be adjusted; however, since the number of connected pieces is n
