Product Description:

The MOT-FC-ET2-V1-355L-4-5CB-315-C3T-HOY is a low-voltage induction motor produced by Bosch Rexroth Indramat within the MOT Low Voltage Induction Motors series. Designed as a mains-powered workhorse for pumps, compressors, and conveyors, this squirrel-cage machine converts three-phase electrical input into continuous rotational output for automated equipment. It serves as the primary mechanical drive for material-handling lines and process equipment where steady shaft speed and dependable torque are required on a fixed-frequency supply. Its operating role is centered on continuous-duty industrial service rather than highly dynamic servo-style motion.

At its rated operating point, the motor delivers 315 kW of shaft power while running on a three-phase supply of 400 V at 50 Hz. The line current required to reach this output is 535 A, and the winding uses a delta connection identified by code D. Under these conditions, the rotor turns at 1480 rpm, which is slightly below synchronous speed so the motor can produce torque through slip. That operating slip produces a continuous mechanical torque of 2025 Nm, making the unit suitable for direct coupling to heavy rotating loads. The A-side and B-side bearings, 6322/C3 and 6322/C3 CIB respectively, support the radial forces created by belt-driven or geared equipment, and the assembled machine mass of 1830 kg helps damp vibration during operation.

For intermittent overloads, the stator can withstand a peak line demand of 1330 A, allowing acceleration to a ceiling speed of 2200 rpm and a short-term torque peak of 4450 Nm. Overall energy performance includes a full-load efficiency of 0.95 and a power factor of 0.90, which help limit heat rise and reduce reactive demand on the feeder. The rotor inertia is 11.1 kg·m², which supports smooth running on high-inertia machinery and slows rapid speed changes. C3 bearing clearance accommodates thermal expansion during prolonged duty, and the bearing arrangement is suited to sustained industrial operation.
