Product Description:

The MOT-FC-ET2- V1-200L-4-5CB- 30-C3T-HOY is an asynchronous motor manufactured by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. It drives pumps, conveyors, and general-purpose machinery that run directly from the mains and are coordinated by external contactors or inverters. The frame employs the IC411 surface ventilated cooling scheme so no auxiliary air source is required inside the cabinet. Rated parameters are balanced for factory power systems operating at 50 Hz and 400 V, giving the unit a place in standard European low-voltage installations.

The motor uses a totally-enclosed fan arrangement identified as IC411, which moves heat off the housing through a shaft-mounted fan and keeps winding temperature within class limits at the full duty point of 30.00 kW. A delta connection on the stator accommodates a line-to-line voltage of 400 V and draws 55.0 A during continuous operation. Under these conditions the rotor settles at 1,470 min⁻¹ and delivers a shaft output of 194.0 Nm. The 50.0 Hz synchronous base is two-pole, so slip is calculated from the 3,000 min⁻¹ theoretical speed. Together, the rated current, power, and torque define the thermal loading profile the drive or contactor must support.

At full load the electrical efficiency reaches 0.92 and the power factor is 0.86, reducing reactive demand on the supply. When the machine accelerates, the drive may momentarily supply up to 446.0 Nm while accepting a peak of 137.5 A. The rotor’s 0.282 kg·m² inertia pairs with two pole pairs to give moderate speed response without producing excessive torque ripple. Overall mass is 243.0 kg, which stabilizes the frame against vibration and simplifies alignment with rigid baseplates. A D-connected winding supports straightforward terminal box wiring and maintains phase symmetry across three-phase feeders.
