Product Description:

The MOT-FC-ET2-V1-280S-4-5CB-75-C3T-HOY is a low-voltage squirrel-cage induction motor from the MOT Low Voltage Induction Motors series. It is intended for constant-speed production machinery and converts three-phase input power into mechanical rotation for industrial drive applications. The IC411 self-ventilated housing removes heat through an external fan, which supports stable operation during continuous duty. A delta stator winding helps keep starting current moderate, and the Class F insulation system permits winding temperatures up to 155 °C in warm industrial environments.

At the nominal operating point, the motor delivers 75.0 kW of mechanical output from a line-to-line supply of 400 V. The resulting current draw is 134.0 A, which is important when selecting feeders and protective devices. At rated load, the shaft runs at 1480 rpm, which corresponds to 50 Hz operation with a four-pole design. Continuous operation at that speed produces 484.0 Nm of torque, and the full-load efficiency of 0.93 means that a relatively small share of the electrical input is lost as heat and windage during steady use.

For short-term overload conditions, the motor can reach 1132.0 Nm of torque without exceeding its thermal limits. During regenerative operation or emergency deceleration, the connected drive must tolerate a DC bus voltage of up to 750 V, and ramp calculations should account for a rotor inertia of 1.29 kg·m². The motor also withstands a peak current draw of 335.0 A during startup, which can reduce the need for reduced-voltage starting methods in some installations. When operated from a variable-frequency inverter, speed can rise safely to 2800 rpm for process-dependent overspeed operation, and the housing maintains a sound pressure level of 72 dB(A) measured at a distance of one meter.
