Product Description:

The MOT-FC-ET2- V1-315L-4-5CB- 200-C3T-HOY is a three-phase low-voltage induction motor manufactured by Bosch Rexroth Indramat in the MOT Low Voltage Induction Motors series. It serves as the primary mover in pumps, fans, and conveyor drives where constant-speed operation is needed. The motor installs in the IM V1 orientation, placing the shaft vertically downward for direct coupling to suspended loads. This vertical arrangement is useful where the driven machine hangs below the motor and floor space is limited. Its delta-connected stator windings are intended for 50 Hz supply networks, making the unit suitable for fixed-speed industrial duty.

At nominal loading, the machine delivers 200 kW of mechanical power and turns at a rated speed of 1480 rpm. That output is developed through a continuous shaft torque of 1290.5 N·m, produced with a line current of 345 A. Conversion losses are limited, giving a full-load efficiency of 0.94. The 0.89 power factor reflects the magnetizing requirements of the iron core while still allowing effective use of feeder capacity. All rated values refer to a 400 V, 50 Hz delta supply, so standard low-voltage switchgear can be used without special transformers. This rating structure supports direct connection to common industrial power systems.

Thermal and dynamic limits set the motor's operating envelope beyond the rated point. A cast-iron housing weighing 1080 kg provides the mass needed to damp vibration and store heat between duty cycles. Surface ventilation follows the IC411 cooling method, which uses an integral shaft-mounted fan to move air across the frame without external blowers. This self-contained cooling arrangement simplifies installation where separate ventilation equipment is not desired. During acceleration or transient overloads, the electromagnetic system can withstand a peak torque of 2970 N·m while the supply may draw up to 860 A. Once running, the rotor's 4.67 kg·m² inertia helps smooth speed fluctuations, and a maximum mechanical speed of 2500 rpm is permitted for short intervals.
