Product Description:

The MOT-FC-NT3-NCB-256T-4-6CL-20-C3L-WEG induction motor is manufactured by Bosch Rexroth Indramat and is part of the MOT Low Voltage Induction Motors series. It is a three-phase squirrel-cage machine intended for industrial automation tasks such as driving fans, pumps, and conveyors where steady mechanical power is required. In integrated production cells, the motor pairs with inverters that adjust speed while the motor itself supplies the rotational energy that moves material or fluid through the process. This arrangement supports applications that need dependable continuous rotation instead of highly dynamic servo-style positioning.

The motor delivers a rated shaft output of 20 hp, which is suitable for medium-frame material-handling stations. Its electromagnetic design uses 4 poles, giving a nominal synchronous speed near 1,800 rpm on 60 Hz supplies and balancing starting torque with running efficiency. Frame code 256T sets the foot-mount dimensions and shaft height, allowing straightforward installation in NEMA-conforming layouts. Energy performance is classified as IE2, which helps limit heat rise during general-purpose operation. External sealing reaches IP55, and the housing resists dust ingress and water jets so the motor can be installed on the factory floor without extra protective covers.

Continuous-duty capability is indicated by operating mode S1, meaning the winding temperature can stabilize at full load without scheduled cooldown periods. Thermal supervision is handled by a PTC sensor type SNM.150.DK, and it responds at 150 °C so the drive can shut the motor down before insulation is overstressed. The winding protection method relies on this thermistor alone, which keeps the temperature-monitoring arrangement simple and direct. The unit can be mounted up to 1000 m above sea level without output derating, allowing standard installation at typical industrial altitudes.
