Product Description:

The MOT-FC-ET2-V1-250M-4-5CB-55-C3T-HOY is a low-voltage three-phase induction motor manufactured by Bosch Rexroth Indramat in the MOT Low Voltage Induction Motors series. It serves as a prime mover in automated machinery, supplying steady shaft power for material-handling lines, pumps, and fans that operate from utility-frequency mains. As an induction motor built for continuous industrial service, it is suited to applications where stable speed, consistent torque delivery, and straightforward integration with plant power systems are required.

The motor is rated for a line-to-line voltage of 400 V on a 50 Hz supply. In delta connection, it delivers 55.0 kW of mechanical output at a rated speed of 1480 rpm. At that operating point, the shaft produces 354.9 Nm while drawing 99.0 A, and the power factor is 0.86 for efficient use of supplied apparent power. Two pole pairs establish the rotating magnetic field, and the rotor inertia of 0.746 kg·m² affects how quickly the motor can accelerate or decelerate when the driven load changes. These characteristics make the unit suitable for equipment that needs dependable full-load operation without complex cooling or special supply arrangements.

For short transients, the motor can withstand 247.5 A and produce a peak torque of 816.0 Nm while staying within the thermal capability of its IC411 enclosure. This self-ventilated cooling method uses frame fins and an integral fan to remove heat without external airflow, which helps simplify installation in enclosed machine areas. The IM V1 mounting form places the motor vertically with the shaft facing downward, and the rotor can reach a mechanical limit of 2800 rpm during rapid deceleration or regenerative events. Total mass is 452.0 kg, and that weight contributes to the rigidity needed for vibration control in heavy industrial installations.
