Product Description:

The MOT-FC-NV3-NCB-256T-4-6CL-20-C3L-WEG is a low-voltage induction motor from Bosch Rexroth Indramat in the MOT Low Voltage Induction Motors series. The unit is intended for use with drive controllers in automated material-handling, pumping, and conveying equipment where precise speed regulation is required. Its three-phase stator and squirrel-cage rotor convert electrical power into mechanical rotation with minimal maintenance. When paired with a variable-speed drive, the motor can support controlled acceleration and stable running speed as process demand changes. That makes it suitable for process lines that need repeatable motor response during starts, stops, and steady-state operation.

At rated load, the machine delivers 20 HP to the shaft. The stator winding is arranged for a 4-pole magnetic field, so synchronous speed matches common 60 Hz converter settings. It is configured for frequency converter operation, allowing vector or V/Hz control across a wide speed range without mechanical tap changers. The cast-iron frame conforms to size 256T, giving a center height and foot pattern compatible with NEMA T-frame gearboxes and pumps. The IP55 enclosure limits dust and water-jet ingress, enabling cabinet-free mounting on factory floors. Electronic speed control can be used without changing the basic mounting footprint of the driven equipment.

The design follows DIN EN 60034 (IEC72), so mechanical dimensions and marking align with widely used industrial standards. Continuous operation is permitted up to 1000 m above sea level without derating, while a closed ventilation path helps maintain thermal balance. As a three-phase cage-runner machine, it uses a cast-aluminum rotor for low slip and strong starting torque. A PTC thermistor embedded in the windings supplies temperature feedback to the converter for staged overload response. The terminal box is positioned above the frame, which simplifies vertical cable entry and helps keep power and control wiring organized in overhead routing.
