How to identify when the mixer has stopped rotating through electrical signals
Thread Content
The mixer is powered by an electric motor, and in many situations, its failure to operate can lead to serious consequences. There are multiple reasons for the mixer to stop operating. The motor stops operating; the mixer shaft breaks; there are connection issues; the mixing blade breaks, etc. The stoppage of the motor can be detected through the current signal indicating its shutdown ； However, outages due to other reasons make it difficult to obtain electrical signals.
The most reliable one, with a speed sensor； Generally, to measure the current level; if it is low, it is considered that the \"slurry/axis is broken.\"
The suggestion from upstairs is good; it can fulfill the functions you need
Installing a speed measurement probe can solve this problem.
Motor protectors can fulfill the functions you need
It can be determined by detecting the current in the motor circuit. If the current drops significantly, it indicates that the load on the motor has suddenly decreased, meaning the aforementioned fault has occurred.
Install low-current protection and set the current threshold for tripping under no-load conditions
