Protective shell for stepping motor

The utility model belongs to the technical field of stepping motor protection, and discloses a protective shell for a stepping motor, which can absorb vibration caused by external impact and reduce the vibration of the external stepping motor by arranging a damping block. And on the other hand, through the arrangement of the fan and the exhaust holes, external air can be blown to the external stepping motor, heat is taken away, the cooling effect is achieved, and the external stepping motor is prevented from being damaged by high temperature. Generally speaking, the device is simple in principle and structure and convenient to use, and has good market popularization value. 本实用新型属于步进电机防护技术领域，公开了一种步进电机用防护壳，通过设置减震块，本实用新型可以对外部冲击造成的震动进行吸收，减轻外部步进电机的震动；另一方面，通过设置风扇和排气孔，本实用新型能将外部的空气吹向外部步进电机，将热量带走，产生降温的作用，防止外部步进电机因高温造成损坏。总体而言，本实用新型的原理、结构简单，使用方便，具有良好的市场推广价值。
