Variable frequency motorIt has the characteristics of frequency conversion speed regulation and can also be calledThree-phase asynchronous motor. todayMori machineXiaobian will take you to understand the relationship between this motor and the frequency converter.

       Variable frequency motorIn recent years, this motor can be described as a "star" product in the equipment manufacturing industry, which can be used under specified standard environmental conditions100%Rated load in10%~100%A motor that operates continuously within the rated speed range and whose temperature rise does not exceed the allowable value of the motor's calibration, but is sometimes burned out because the inverter is incorrectly set.

       Some customers buy a frequency converter device according to the motor power, but the two are connected together without setting, so that it is easy to burn, because the device at this timeVariable frequency motorNo protection function Settings; The correct approach is to input some parameters of the purchased motor into the device, and set some parameters related to the protection of the motor. If the parameters and protection are not set for the motor, then the default protection current of the device exceeds the rated current of the motor, and the inverter will not stop to protect the motor because of the overload current, resulting in the motor burning.

       The following isShengzhou Chaoli electric appliance factorySort something aboutVariable frequency motorSome methods to set up when using the inverter:

       Protection mode. The protection methods available for overload are: motor deceleration stop, immediate power off free stop, motor current limiting operation.

       Overload protection time delay.When the overload current reaches the protection set value, the time allowed to continue running will be implemented when it exceeds the protection, and the current will return to normal within the delay time and exit the protection; When the overload current exceeds the protection set value, the protection is implemented according to the inverse time characteristic.

       When we use a frequency converter to control a motor, overload protection should be set; If it is to control multiple units, measures such as thermal relay protection or motor protector protection should be taken according to the capacity of each motor.
