There are many forms of motor protection measures, different protection measures corresponding to different uses, to the common overload protection, for example, in the three-phase asynchronous motor auxiliary failure, if the long-term over-fixed current operation, it will lead to overheating, insulation reduction will lead to burn. Here is a simple understanding with Senli Motor Xiaobian.

       Off-phase protection inThree-phase asynchronous motorPlay a very important role in; When the phase failure operation is very harmful, when the phase failure or three-phase current is seriously unbalanced, such as the imbalance rate reaches the protection set value, the protector protects according to the set requirements, and issues stopping or alarm instructions, so that the motor is safer to run.

       Lock-rotor protection can be a good protection of three-phase asynchronous motor in the starting or running process, because the load is too large, or the mechanical itself caused by the shaft jamming phenomenon. When the voltage is too low, it will cause the motor speed to decrease, then we can use the undervoltage protection device, when the voltage drops to the set undervoltage protection range, the protector will be protected according to the set requirements.
