Product Description:
The MOT-FC-ET2-B35-315S-4-5CB-110-C3T-HOY is an asynchronous three-phase machine produced by Bosch Rexroth Indramat within the MOT Low Voltage Induction Motors series. In automated factories, this motor links a 400 V drive stage to mechanical loads, providing continuous rotational energy for pumps, fans, or conveyor shafts that need steady speed and high efficiency. By using standardized mounting interfaces, it integrates with gearboxes and drive packages used across general-purpose automation cells. This type of motor is suited to applications that require dependable continuous rotation rather than rapid cyclic positioning.
At its nominal operating point, the motor delivers 110 kW of shaft power while drawing 192 A from a 400 V line at the standard 50 Hz supply frequency. The electromagnetic design reaches 0.94 full-load efficiency, so only a small share of the input energy is converted into heat inside the frame. A displacement power factor of 0.88 keeps reactive current low and reduces unnecessary loading on upstream supply equipment. The four-pole rotor runs at 1480 rpm and generates 709.8 Nm of rated torque through a delta-connected stator winding. These steady-state values represent the continuous operating point, where thermal rise, vibration, and acoustic noise remain within long-term limits for ongoing production duty.
For transient demands, the drive can supply 480 A on a 750 V DC bus, letting the motor produce short bursts up to 1633 Nm without exceeding insulation class F limits. A rotor inertia of 2.87 kg·m² balances acceleration capability with speed stability, which helps the motor start heavy loads in a controlled manner. The 840 kg mass contributes to structural damping and supports stable installation on a B35 flange-and-foot mounting frame. Thermal protection is provided by a winding shutdown threshold of 155 °C, which the control system can use to trigger a safe stop before damage occurs. This shutdown point helps protect the winding system during overload or restricted cooling conditions.
