Stator punching sheet for variable-pitch direct-current motor

The utility model provides a stator punching sheet for a variable-pitch direct-current motor, which comprises a stator yoke part which is annularly arranged, and a cavity for mounting a stator tooth part is formed inside the stator yoke part; the stator tooth part is integrally stamped on the inner side of the stator yoke part and horizontally extends towards the center to form a tooth-shaped structure; the stator tooth part comprises multiple groups of excitation main pole groups and multiple groups of commutation magnetic pole teeth, and the excitation main pole groups and the commutation magnetic pole teeth are arranged at equal intervals; the compensation coils are wound among the excitation main pole groups; and the commutation coils are wound among the commutation magnetic pole teeth. According to the utility model, a plurality of excitation main pole groups and commutation magnetic pole teeth which are arranged at equal intervals are integrated in the stator tooth part, so that the purpose of integrati
