Have you considered the reason for the abnormal noise of the UV flatbed printer? The motor may be out of phase. What is the phenomenon of phase loss during operation?

(1) The motor speed drops;

(2) The temperature of the motor body rises;

(3) One phase without an ammeter is disconnected, and the motor current increases;

   One phase where the ammeter is installed is disconnected, and the ammeter indicates zero.

(4) There is a strong “humming” sound at startup, but it cannot be started, or the normal rotation cannot be achieved after startup.speed.

What are the hazards of lack of phase operation?

        When the above phenomenon is found, it should be stopped immediately and it is strictly forbidden to start, otherwise the motor will be burned.

Are there any protective measures?

         To prevent the motor from running without phase, first of all, it is necessary to strengthen the monitoring and inspection during operation, and secondly, some suitable automatic protection measures can be taken.
