The Bosch Rexroth IndraDyn E MOT-FC low-voltage induction motor series comprises three-phase squirrel-cage AC motors intended for industrial use with either a frequency converter or direct mains operation.
The series covers an IEC-based power range from 1.5 to 315 kW, typically in a 4-pole configuration (about 1500 min⁻¹ nominal speed), with IE2 energy efficiency specified as the baseline. Nominal voltage is defined as 230/400 V for ratings under 3 kW and 400/690 V for ratings above 3 kW, aligning the lineup with common low-voltage three-phase supply systems. For mechanical integration, MOT-FC variants are available in multiple IEC mounting forms (including IM B35, IM B5, and IM V1) and use aluminum housings for smaller frames and gray iron housings for larger frames. Thermal and protection design includes self-ventilated (IC411) or forced-ventilated (IC416) versions, typical operation around −20 to +40 °C up to 1000 m, and three PTC sensors (one per phase) for temperature monitoring.
