Product Description:

The MOT-FC-ET2-B35-180M-4-5CB-18,5-C3T-HOY is a low-voltage three-phase induction motor manufactured by Bosch Rexroth Indramat and supplied within the MOT Low Voltage Induction Motors series. It is intended for general-purpose industrial automation where a constant-speed mains machine is required to drive pumps, compressors, or gearboxes directly from a 400 V utility network. The design maintains an IP55 housing so dust ingress and low-pressure water jets do not interfere with continuous plant operation.

Under nominal conditions the motor delivers 18.5 kW of mechanical output while connected to a 400 V, 50 Hz supply arranged in winding interconnection D. At this operating point it turns at 1460 rpm and produces a shaft torque of 120.0 Nm. Electrical efficiency is 0.91, limiting copper and iron losses and reducing panel heat dissipation requirements. The power factor remains 0.86, so reactive current is moderate relative to active power flow. A rated current draw of 34.0 A aligns with typical IEC-frame conductors, and two pole pairs cooperate with the 50 Hz excitation to set synchronous speed near 1500 rpm. The frame carries a degree of protection IP55, allowing installation in wash-down areas without auxiliary enclosures.

For transient or overload events the stator can accept a DC bus up to 750 V from a matched inverter. During such events line current may rise to 85.0 A and the electromagnetic system can deliver as much as 336.0 Nm of peak torque before thermal limits intervene. The motor’s rotor inertia is 0.16 kg·m², providing a balance between speed stability and acceleration when driven by vector-controlled converters. A power factor of 0.86 at full load supports reasonable utilization of drive VA capacity without excessive reactive compensation equipment. The stator winding follows the D configuration, and all connectors are routed through a B35 form factor that combines foot and flange mounting to simplify alignment inside modular machine frames.
