Product Description:
The MOT-FC-ET2-B35-280S-4-5CB-75-C3T-HOY is a low-voltage, three-phase AC motor produced by Bosch Rexroth Indramat within the MOT Low Voltage Induction Motors series. It converts electrical energy from automation drives into rotational shaft power for pumps, compressors, and conveyor stations that need consistent mechanical output on a 400 V utility grid. Its role inside an automated cell is to provide continuous torque while meeting plant requirements for efficiency, thermal behavior, and acoustic limits.
At the nominal operating point, the machine delivers 75 kW of power when supplied with 400 V at a rated frequency of 50 Hz. The stator draws a rated phase current of 134 A, and the full-load electrical design achieves a power factor of 0.87 to keep reactive demand low on the feeder. Energy conversion remains efficient because copper and iron losses are balanced to reach 94.00% efficiency under continuous load. Two pole pairs establish the synchronous field, giving a rated shaft speed of 1480 rpm while keeping slip within normal induction ranges. A D connection is used in the winding set so that the line-to-line voltage equals the phase voltage, simplifying starter and drive selection.
The rotor can accelerate process equipment quickly because its inertia is 1.29 kg·m², and the frame permits a peak shaft speed of 2800 rpm without overspeed resonance. During demanding transients, the stator can tolerate 335 A, and the electromagnetic system produces a maximum torque of 1060 Nm before saturation. Under steady conditions, the shaft supplies 483 Nm at the rated speed of 1480 rpm, while structure-borne noise is limited to 72 dB(A), making the motor suitable for indoor installation. The cast-iron housing, end bells, and foot-flange combination bring the total mass to 592 kg, providing thermal mass for heat dissipation and mechanical stiffness for baseplate mounting.
