Self-buffering permanent magnet motor

The invention provides a self-buffering permanent magnet motor. The problem that the motor is easy to loosen after being used for a long time is solved. When the motor is used, one end of the end cover enables the second transverse plate to be fixedly arranged on the motor body through a bolt, the rotating shaft penetrates through the end cover to complete fixation of the other end of the end cover, and a certain gap is reserved between the first vertical plate and the periphery of the motor body and between the first transverse plate and the periphery of the motor body, a moving gap is reserved between the motor body and the end cover when the motor body vibrates in use; displacement generated by vibration between the motor body and the end cover is absorbed through a first limiting column and a second limiting column which are fixedly arranged on the motor body and the end cover respectively and a spring of which the two ends sleeve the first limiting column and the second limiting column respectively, so t
