Product Description:

The MOT-FC-NT3-FCB-365T-4-6CL-75-C3L-WEG is an AC induction motor built by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. In automated plants, it converts three-phase electrical power into continuous rotary motion for pumps, conveyors, and mixers that run at a constant base speed yet face variable process loads. The totally enclosed motor is suitable for low-voltage drive systems and provides a straightforward mechanical interface to downstream equipment in assembly, packaging, and material-handling stations.

Delivering 75 HP at the shaft, the motor supports mid-range machinery that needs steady mechanical output. A dual-voltage nameplate rating of 230/460 V permits connection to common industrial power supplies without rewinding. At those voltages, the stator draws 174/87.2 A, and these values are used to size conductors, circuit breakers, and variable-frequency drives. Combining the 60 Hz line frequency with a 4-pole rotor yields a rated speed of 1780 rpm, providing enough slip for torque development while limiting vibration during continuous operation. When paired with the rated torque of 221 ft-lb, this speed provides predictable horsepower across the operating load curve.

An electrical-to-mechanical conversion efficiency of 95.4% keeps winding temperatures low and minimizes ventilation requirements. The full-load power factor of 0.83 limits reactive demand, reducing strain on the plant electrical system. Protection is enhanced by an IP55 housing that uses an IC411 totally enclosed, fan-cooled design, so airborne dust and water jets do not contact live components while an external fan moves cooling air over the frame. A Type C flange simplifies alignment with gearboxes or centrifugal pumps, and the assembly weighs 922 lb, giving it the thermal mass needed to maintain stable operating temperatures during long production runs.
