Product Description:
The MOT-FC-NT3-FCB-254T-4-6CL-15-C3L-WEG is a low-voltage induction motor manufactured by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. It is intended for constant-speed drive tasks in pumps, fans, and conveyors where reliable three-phase rotation is needed without variable-frequency equipment. The design combines a cast-iron housing with an integral fan, allowing the motor to be installed directly on a baseplate or C-face mount while keeping its overall dimensions within common NEMA 254T outlines. Its enclosed construction protects internal electrical parts while the external housing provides a rigid structure for industrial machinery.
An IC411 totally enclosed fan-cooled arrangement moves ambient air over external ribs, keeping the internal temperature stable. The housing has an IP55 ingress protection rating that blocks dust and low-pressure water jets. Continuous service is supported by the S1 duty rating, and the frame follows the 254/6TC dimensional code for standardized foot and flange patterns. When powered from a 60 Hz grid, the motor has a full-load efficiency of 92.4 %, limiting electrical losses in energy-sensitive installations. The foot-mounted configuration includes a C-flange and F-1 hardware, allowing direct coupling to gearheads or pump casings while keeping the shaft centerline aligned with existing machinery.
The motor delivers 15 HP at the output shaft while drawing a rated current of 14.4 A from the supply. Mechanical power is transferred at a base speed of 1770 rpm, reflecting normal motor slip during operation on a 60 Hz supply. The nominal connection voltage is 575 V, permitting direct use on compatible industrial power networks without a step-up transformer. The terminal box is positioned on the left side to simplify conduit routing and maintain clearance around the drive end. Stator temperature is monitored by a built-in PTC sensor that can activate a protection circuit or thermal relay during blocked ventilation or overload conditions. This monitoring helps prevent winding damage when the motor temperature exceeds the permitted operating range.
