Product Description:
The MOT-FC-NT3-NCB-184T-4-6CL-5-C3L-WEG is an induction motor produced by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. Designed for operation with a frequency-controlled drive, this squirrel-cage motor converts electrical energy into shaft torque for conveyors, pumps, fans, compressors, and general industrial machinery. Its 184T frame and foot-mounting dimensions follow NEMA patterns, allowing the motor to fit compatible machine bases without additional mounting brackets. The asynchronous design provides stable operation across a broad load range while the connected drive regulates acceleration, speed, and torque.
The motor provides a continuous output of 5 HP, making it suitable for moderate mechanical loads in industrial equipment. Its windings accept 230/460/380 V supplies with the appropriate delta or wye connection, supporting operation with common North American and international power systems. Compatibility with 60/50 Hz power allows the motor to operate on regional grids or through a variable-frequency drive. The NEMA Premium efficiency class reduces electrical losses and heat generation at the nominal operating point. A three-phase stator distributes electrical power evenly across the conductors and produces a rotating magnetic field for smooth torque delivery. The four-pole arrangement provides a synchronous speed near 1,800 rpm when supplied at 60 Hz. Frequency-converter-rated insulation and bearings tolerate the voltage pulses and operating conditions associated with inverter duty.
The TEFC enclosure limits the entry of dust and other contaminants while preventing outside air from passing through the motor interior. An enclosed fan moves cooling air across the external housing fins in accordance with the IC411 cooling method, helping remove heat during continuous operation. The enclosure carries an IP55 protection rating, providing resistance to dust ingress and water jets from multiple directions. Embedded PTC temperature sensors monitor thermal conditions and allow the connected inverter or protection circuit to respond before excessive winding temperatures damage the insulation. The foot-mounted housing provides a stable base for shaft alignment with pumps, gearboxes, and belt-driven equipment. Its brushless rotor reduces wear because it does not require commutators, slip rings, or carbon brushes. Torque remains available from startup through base speed when the motor is paired with a properly configured drive.
