Motor iron core and motor

The utility model relates to the technical field of motors, and provides a motor iron core and a motor, the motor iron core comprises an iron core body, the iron core body is arranged in an annular shape, and the iron core body comprises a plurality of block iron cores which are assembled with one another; the two opposite sides of each block iron core are provided with binding faces, and the adjacent block iron cores are spliced through the binding faces. And the connecting piece is arranged outside the iron core body and is used for clamping each block iron core. By means of the mode, in the assembling process of the block iron core, a complete attaching and assembling mode is selected instead of forming grooves in the ends and arranging protruding edges for matching and assembling, and therefore automatic assembling of the block iron core can be achieved, the production efficiency of the motor is improved, the production cost is reduced, and the electromagnetic performance of the motor is also improved. 本实
