Stator coil rack of stepping motor and stepping motor

The invention provides a stator coil rack of a stepping motor. The stator coil rack comprises an upper pole plate, a middle pole plate and a rubber-coated integrated framework, wherein the rubber-coated integrated framework is provided with an upper framework, a lower framework and a gear plate, and the gear plate, the upper framework and the lower framework are sequentially connected; the rubber-coated integrated framework is provided with a middle hole; the upper pole plate and the middle pole plate are provided with pole tooth groups; the pole tooth groups are embedded in the hole wall of the middle hole. The invention also provides a stepping motor. The stepping motor comprises a casing assembly, a rotor assembly, a stator assembly and a cover plate. The stator assembly comprises the stator coil rack. The stator coil rack and the stepping motor have the advantages that firstly, the stator coil rack is integrally formed through rubber coating, so that the assembling process and theredundant detection proce
