What are the basis of the frequency converter to choose?
According to the applied industry.The application of inverter industry RGB field is widely used, the main products are: SAJ-S simple ultra small, SAJ-M mini, SAJ-G universal, SAJ-F type, SAJ-P type wind pump, SAJ-Y injection molding machine type, SAJ-Z type, heavy machine industry, naked personalized products, high performance vector inverter S350.
1, brand, mainly for cost control2, performance, overload, function, reliability,3, load characteristics, constant torque, square torque or special load (determine the length of the cable of the load motor)4, environmental aspects: temperature, humidity. Altitude.These are the needs of attention when type selection.The last point is the most important, when choosing type, remember that the motor power can not be selected, must be selected in accordance with the motor current.
1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。3. when the load is large, the braking unit and the braking resistor should be selected simultaneously.4. check the motor nameplate current rating (no nameplate rated current). The rated current of the inverter is greater than the maximum running current of the motor
