Variable Frequency Drives (Frequency Inverters)
Frequency inverters are AC motor drives that adjust the speed and torque of an asynchronous motor by converting the fixed-frequency mains voltage into variable frequency and voltage. They are used in pump, fan, compressor and conveyor drives to provide soft start and stop, to adjust speed according to the process, and to reduce energy consumption at partial flow in pumps and fans. The category lists single- and three-phase drives from brands such as ABB, Schneider Electric, Delta Electronics and GMT in motor powers such as 0.75 kW, 2.2 kW, 7.5 kW and 15 kW; solar pump drives, braking resistors and drive accessories are in separate subcategories. When choosing a variable frequency drive, compare the power and rated current on the motor nameplate with the drive's motor power and output current, and compare the supply phase and voltage with your mains; choose according to whether the load has constant or variable torque, the communication protocol, and the degree of protection such as IP20 or IP21. For loads with frequent stops or high inertia, a suitable braking resistor may be needed, and for long motor cables, the output filter recommended by the manufacturer.
