Drive Sizing for Procurement
The Omron 3G3MX2-A4007-E frequency inverter delivers 0.75 kW at constant torque and up to 1.5 kW on variable-torque loads, making it a direct fit for pump and fan drives within that envelope. It operates from a 3-phase 380-480 VAC line and outputs the same voltage at 0.1–1000 Hz, covering standard induction motors and high-speed spindles. Rated input current sits at 4.1/3.4 A corresponding to the two torque ratings; the IP20 enclosure keeps it inside a cabinet, with ambient tolerance of -10 to 50 °C.
