Stepping motor

The invention relates to a stepping motor. The stepping motor comprises a rear end cover (2), a front end cover (3), a stator assembly (5), a motor self-fixing screw (6), an outgoing line (8), a rotor assembly (9), a front framework (10) and a rear framework (11); and the motor self-fixing screw (6) sequentially penetrates through the front end cover (3), the front framework (10) and the stator assembly (5) and then is fixed to a first motor self-screw mounting hole (16) in the rear end cover (2), the outgoing line (8) is led out from the rear end cover (2), and a first mounting fixing hole (7) used for the motor is formed in a motor body. Compared with the prior art, the motor has the advantages that the size of the motor is saved, and the power density of the motor is improved. 本发明涉及一种步进电机，包括后端盖(2)、前端盖(3)、定子组件(5)、电机自身固定螺钉(6)、引出线(8)、转子组件(9)、前骨架(10)和后骨架(11)；所述的电机自身固定螺钉(6)依次穿过前端盖(3)、前骨架(10)、定子组件(5)后与后端盖(2)上的第一电机自身螺钉安装孔(16)固定，所述的引出线(8)从后端盖(2)上引出，所述的电机机身内设有用于电机使用的第一安装固定孔(7)。与现有技术相比，本发明具有节省了电机的体积，提升了电机的功率密度等优点。
