THREE-PHASE JM CLOSE-COUPLED PUMP MOTOR What electrical protection measures are there to avoid motor damage or fire?
THREE-PHASE JM CLOSE-COUPLED PUMP MOTOR adopts a variety of electrical protection measures to avoid motor damage or fire. These measures are designed to ensure that the motor can operate safely or shut down in time in the event of electrical faults or abnormal conditions, thereby protecting the motor and related equipment from damage and preventing the occurrence of dangerous situations such as fire. The following are the main electrical protection measures used in motors:
Overload protection:
The motor has a built-in overload protection device that is triggered when the load on the motor exceeds its rating. This is usually achieved by detecting whether the motor current exceeds a set value. Once an overload condition is detected, the protection device cuts off power or reduces motor output to prevent motor overheating, winding burnout, or other damage.
Short circuit protection:
The motor circuit is equipped with a short-circuit protection device to detect and respond to short-circuit faults. A short circuit may cause the current to rise rapidly, causing motor damage or fire. The short-circuit protection device can quickly cut off the fault circuit and prevent excessive current from causing damage to the motor and other equipment.
Undervoltage and overvoltage protection:
The motor has undervoltage and overvoltage protection functions. These protection devices activate when the supply voltage is below or above the rated voltage range of the motor. Undervoltage may cause the motor to operate erratically or fail to start, while overvoltage may cause damage to the motor insulation. These protection devices can protect the motor from damage by detecting the power supply voltage and cutting off the power supply or adjusting the motor working status when the voltage is abnormal.
Overcurrent protection:
The motor also has an overcurrent protection function, which is used to detect whether the motor current exceeds the normal operating range. Overcurrent may be caused by internal faults in the motor, abnormal load, or power supply problems. Once an overcurrent condition is detected, the protection device will quickly cut off the power supply to prevent damage to the motor or cause a fire.
It should be noted that specific electrical protection measures may vary depending on the motor model, manufacturer and application scenario.
