Dynamic balance detection device for rotating shaft of high-voltage motor

The invention relates to the technical field of high-voltage motors, in particular to a high-voltage motor rotating shaft dynamic balance detection device which comprises a high-voltage motor, a high-voltage motor body, a mounting frame, a rotating shaft arranged at the output end of the high-voltage motor body and a belt pulley. The limiting mechanism comprises a flying disc arranged on the outer wall of the rotating shaft in a sleeving mode, a shell arranged outside the flying disc, a brake block arranged in the shell in a sliding mode and a sliding column. The transmission mechanism comprises a disc, a sliding rail and an alarm lamp; the control mechanism comprises a rotary disc, a fixed disc and a control arm; the dynamic balance degree of the rotating shaft is sensed by arranging the flying disc on the rotating shaft of the high-voltage motor in a sleeving mode, the flying disc slows to drive the brake block to decelerate the flying disc, the rotating shaft is clamped through the pulley, damage to the be
