Product Description:

The MOT-FC-NT3-FCB-405T-4-6CL-100-C3L-WEG is an AC induction motor produced by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. Designed for continuous operation in manufacturing and process plants, the unit converts three-phase electrical power into steady shaft torque that drives pumps, fans, conveyors, and gear reducers. This operating style is commonly used where motors run for long periods under stable load conditions rather than in short intermittent cycles. Its frame dimensions follow established industry footprints, allowing it to fit common base and coupling arrangements in existing equipment without major mechanical changes.

The motor is sealed to IP55, which helps keep dust out and allows exposure to low-pressure water jets, so cabinet placement is not mandatory. High electrical performance is indicated by the NEMA Premium efficiency class, which reduces heat losses during full-load operation. The stator housing is made of Gray Cast Iron, adding mass for vibration damping and improving mechanical strength in demanding installation sites. That housing material also helps the assembly resist distortion in areas exposed to persistent machine vibration. Thermal safeguarding is provided by integrated PTC sensors that open the control circuit when winding temperature approaches its limit. The motor uses an AC squirrel cage design, so startup current can be managed by standard soft starters or variable frequency drives without brushes or slip rings.

The motor uses a 3-phase electrical configuration, ensuring balanced line currents and compatibility with common 50 or 60 Hz supply networks. Its 4-pole layout establishes a synchronous base speed near 1,800 rpm on a 60 Hz system, which suits centrifugal loads that need moderate operating speed. On a 50 Hz supply, the same pole count produces a lower synchronous speed that is often suitable for similar process duties. Field wiring is simplified by the left-side terminal box, which provides clear access when the motor is mounted with its drive end toward the machinery. This layout is suitable for automated conveyors, mixers, and HVAC blower assemblies.
