Product Description:

The MOT-FC-ET2-B35-315L-4-5CB-200-C3T-HOY induction motor is built by Bosch Rexroth Indramat within the MOT Low Voltage Induction Motors series. It is a three-phase squirrel-cage unit intended to convert electrical energy into mechanical shaft work for pumps, compressors, and conveyor stations installed in automated plants. By combining a standard IEC frame with dynamically balanced steel laminations, the motor offers a direct-mount option for drive controllers that regulate speed through voltage and frequency variation. Its mechanical interface follows common B35 footing and flange dimensions, allowing horizontal or vertical installation.

Under nominal conditions, the machine accepts a line-to-line supply of 400 V at 50 Hz through a delta winding connection. At this operating point, the stator draws 345 A and delivers 200 kW of mechanical power while the rotor spins at 1480 rpm. The resulting electrical-to-mechanical conversion reaches a full-load efficiency of 0.94, which helps limit thermal rise during continuous operation. The motor uses self-ventilated IC411 cooling, so air moves across the frame without external blowers. Acoustic emission is measured at 76 dB(A), and the 6319/C3 bearing at the drive end carries radial forces generated by belt drives. Field wiring remains straightforward because the delta terminals are accessible in a top-mounted box protected against dust ingress.

Torque capability affects how the motor couples to gear stages and driven loads. Continuous duty can be sustained at a shaft load of 1290.5 Nm. Process surges may be absorbed momentarily up to 2970 Nm without stalling. These operating reserves are supported by a permissible stator current that peaks at 860 A during acceleration. A rotor inertia of 4.67 kg·m² moderates speed fluctuations and gives predictable ramp times when the unit is linked to vector drives sized for the motor's power and speed range.
