With the installation of eccentric block on the both side of motor shaft, vibrating motor applies the exciting force with high rotation speed to make the machine working. It is widely used in many industries for its simple and compact structure, easy installation, joint vibrating without transmission device. However, due to it special structure, the service life of vibrating motor is shorter than that of normal motor. Therefore, we should pay more attention to the damage reason. The damage reasons are anchor bolt loose, installation problem, eccentric block regulation problem, seal of protection cover, environmental temperature and heat dissipation.
