Product Description:
The MOT-FC-NT3-FCB-444T-4-6CL-125-C3L-WEG is a low-voltage induction motor produced by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. It converts electrical energy into mechanical shaft power for compressors, pumps, conveyors, and other equipment in automated plants. The motor uses the standard industrial 444/5T frame, which provides the shaft height and mounting footprint required by machinery designed for this frame size. It is supplied without a flange and mounts to a base plate, allowing the shaft to connect to driven equipment through a suitable coupling. This arrangement supports rigid installation on structural steel while leaving space around the shaft for alignment and routine access.
This model delivers a continuous shaft output of 125 HP while drawing up to 139 A at a rated line voltage of 460 V. At full load, the motor reaches an efficiency of 95.4 %, limiting the portion of input power that is converted into heat. Its four-pole rotor operates with a stator field rotating at a synchronous speed of 1800 rpm. A small amount of rotor slip develops under mechanical load, allowing the induction motor to produce the torque needed by the connected machine. These operating values help determine conductor capacity, overload protection, and drive selection for full-torque acceleration. The winding and rotor arrangement also support continuous operation when the motor remains within its permitted electrical and thermal limits.
The housing has a protection rating of IP55, which guards internal components against dust and water jets during outdoor use or operation in washdown areas. Cooling air passes over the totally enclosed, finned housing through the IC411-TEFC cooling arrangement. The external fan directs airflow along the enclosure so heat can leave the motor without exposing the windings to surrounding air. The unit is designed for a supply frequency of 60 Hz and operates on three-phase power. A foot-mounted base supports alignment with the driven equipment, while the terminal box is positioned on the left side for cable routing alongside the frame. The enclosure and cooling method make the motor suitable for industrial locations where airborne contaminants or occasional water exposure may be present.
