Product Description:

The MOT-FC-ET2-B35-355L-4-5CB-315-C3T-HOY is a low-voltage induction motor built by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. It supplies rotary power to conveyors, pumps, and other continuous-duty equipment in automated plants. The frame uses combined flange and foot supports in the B35 mounting configuration, allowing the housing to be secured directly to machinery. This arrangement also supports accurate shaft alignment with a gearbox, rigid coupling, or driven load. Its large frame is suited to industrial systems that require sustained mechanical power during extended operating cycles.

The motor delivers a rated mechanical output of 315.0 kW when supplied with 400 V from a three-phase network. At rated load, it draws 535.0 A, rotates at 1480 rpm, and produces 2032.6 Nm of shaft torque. These ratings support appropriate selection of supply conductors, circuit protection, drive components, and load gearing. The electrical design uses a D connection and is configured for a mains frequency of 50 Hz. Two pole pairs establish the synchronous speed reference for the induction rotor. An IC411 self-ventilated cooling system circulates air over the stator core to remove heat generated during operation. The motor produces a nominal airborne sound pressure level of 82 dB(A) at full load, which should be considered when selecting acoustic barriers or locating the equipment.

During dynamic operation, the shaft can produce up to 4675.0 Nm of torque, while the stator can momentarily draw 1337.5 A during acceleration. The motor supports speeds up to 2200 rpm without exceeding its mechanical operating limit. Its rotor has an inertia of 11.1 kg·m², which affects acceleration, deceleration, and the drive system’s response to changing loads. The bearing arrangement uses 6322/C3 rolling elements, with the A-side bearing managing thrust and the companion bearing supporting the opposite end. A precision B-side bearing seat maintains alignment between the rotor, shaft, and connected equipment. The cooling path supports long operating periods under cyclic loads without requiring a separate liquid-cooling circuit.
