Product Description:

The MOT-FC-NV3-FCB-256T-4-6CL-20-C3L-WEG induction motor is produced by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. It is a three-phase squirrel-cage motor intended to operate from inverter outputs in automated conveyors, pumps, and material-handling lines. The motor converts the variable-frequency power supplied by the drive into mechanical rotation, allowing precise speed regulation without mechanical gear changes in industrial automation cells. Its induction design supports dependable operation across applications that require adjustable speed and continuous rotary motion.

Compliant with DIN EN 60034 (IEC 72), the motor follows widely adopted dimensions and electrical requirements for standardized machinery. Its IE2 efficiency rating indicates moderate energy performance that helps limit heat generation when the motor operates with a modern inverter. The 256T frame code indicates the shaft height and mounting footprint, providing the dimensions needed to select bolt patterns and coupling sizes. The motor is rated for frequency-converter duty, so its insulation system tolerates the fast voltage edges and higher rates of voltage change produced by pulse-width-modulated inverters. Its IP55 enclosure rating protects the stator against dust and water jets, supporting installation in dusty production areas or locations subject to washdown. The enclosure also helps shield internal electrical components from common industrial contaminants during routine operation.

The motor delivers 20 HP of mechanical output at its rated operating point, providing suitable power for medium-capacity fan, pump, and conveyor applications. It can start and run at ambient temperatures from -20 to +40 °C, allowing operation in unheated warehouses and warm process areas. Operation is permitted at elevations up to 1,000 m above sea level, where thermal performance and dielectric strength remain within the intended limits. A built-in PTC thermistor embedded in the windings sends temperature information to the inverter’s thermal input, allowing a controlled shutdown before the motor overheats. The cast-iron housing helps dampen vibration during operation. A terminal box mounted above the frame supports top-entry conduit routing while keeping the phase leads short between the motor and drive cabinet.
