Product Description:

The MOT-FC-ET2-V1-355M-4-5CB-250-C3T-HOY is an induction motor manufactured by Bosch Rexroth Indramat within the MOT Low Voltage Induction Motors series. It converts three-phase electrical power into shaft rotation for conveyors, pumps, and material-handling equipment inside automated production lines. Designed for fixed-speed duty, the unit interfaces with standard contactor starters or variable-frequency drives to supply reliable mechanical energy to downstream equipment. Its frame size and mounting arrangement follow common industrial patterns, allowing straightforward integration into existing motor beds. This motor is suited to applications that run for long periods under steady load rather than rapid indexing motion.

At the nominal operating point, the machine produces 250.0 kW of mechanical power while drawing three-phase current from a 400 V supply at 50 Hz. The stator windings use a D connection, and the rated line current is 425.0 A. With this excitation, the rotor stabilizes at 1480 rpm, delivering a continuous shaft torque of 1613.2 Nm. The double-row deep-groove bearings labeled A 6322/C3 and B 6322/C3 CIB support radial loads during this service point and help maintain stable rotor alignment. Electrical and mechanical losses are low, resulting in a full-load efficiency of 0.94. Two pole pairs establish the synchronous field, and a rotor inertia of 8.02 kg·m² supports smooth running during load changes.

For short-duration overloads, the stator can accept 1062.5 A, allowing the shaft to reach a maximum torque of 3710.0 Nm while remaining inside insulation and thermal limits. During continuous duty, the machine holds a power factor of 0.90, which helps limit reactive demand on the supply network. Its sound pressure level of 82 dB[A] indicates that hearing protection may be appropriate in nearby work areas, depending on the installation. This overload capacity helps the motor absorb temporary load spikes during startup and repeated process changes without interrupting normal operation.
