Product Description:
The MOT-FC-ET2-B35-225M-4-5CB-45-C3T-HOY is an asynchronous machine manufactured by Bosch Rexroth Indramat within the MOT Low Voltage Induction Motors series. As a four-pole cage-rotor motor, it supplies constant-torque drive power to conveyor lines, pumps, and other fixed-speed stations in automated production cells. Its enclosure and foot-and-flange mounting pattern allow the unit to fit existing IEC frames while maintaining alignment with gearboxes and couplings. The mounting arrangement also supports secure attachment where both base support and direct flange connection are required.
The motor develops a continuous output of 45.00 kW when connected to a three-phase supply at 400 V. At this operating point, it turns at 1475 rpm and delivers a shaft torque of 290.0 Nm while drawing a steady line current of 81.0 A. These ratings indicate the continuous workload that the stator can support and help determine suitable starter, overload relay, and upstream cable capacities. A delta-connected stator winding carries the phase currents, while the two pole pairs provide a synchronous speed close to 1500 rpm on a 50 Hz supply. The difference between synchronous and rated speed provides the slip required for induction motor operation.
Energy conversion efficiency reaches 0.93 at full load, so electrical losses remain modest during continuous operation. The motor can produce up to 667.0 Nm during acceleration or brief overload conditions, providing additional torque when the connected machinery starts under load. The cast-aluminum rotor has an inertia of 0.590 kg·m², which moderates speed fluctuations when process torque changes suddenly. With a total mass of 328.0 kg, the stator frame provides thermal mass and vibration damping while allowing the motor to be moved with appropriate lifting equipment. The machine has a power factor of 0.86, limiting reactive demand on the electrical supply during normal operation. Its maximum mechanical speed is 2800 rpm, which establishes the upper operating limit for the shaft and bearings. The rated frequency is 50.0 Hz, making the motor suitable for standard European industrial power systems.
