How should Frequency Inverters be evaluated?
Inverter selection adds load characteristic, speed range, overload duration, braking, mains and control method to the motor nameplate power. The relationship between Motor current and constant/variable-torque load and Mains, EMC, I/O and communication is examined for Pump and fan control against the nameplate and circuit record, then carried into Motor-parameter commissioning list.
Before Motor-parameter commissioning list is produced, Speed range, overload and braking for Conveyor speed regulation is measured against the nameplate and circuit record; brand preference stays inside that technical window.
Motor current and constant/variable-torque load, Speed range, overload and braking and Mains, EMC, I/O and communication are compared against the nameplate and circuit record through Pump and fan control, Conveyor speed regulation and Mixer and winder drives respectively.
