Product Description:

The MOT-FC-ET2-V1-225S-4-5CB-37-C3T-HOY is a three-phase induction motor manufactured by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. It serves as a constant-speed prime mover in automated lines, providing mechanical energy to pumps, fans, or gearboxes where low-voltage mains supplies are standard. Designed for enclosed fan cooling and foot mounting, the unit integrates directly with Bosch Rexroth drive packages and other IEC-compliant starters used throughout industrial automation.

The motor follows the IC411 self-ventilated cooling scheme, allowing ambient air to be drawn over the fan and stator housing. Its continuous output is 37.0 kW with a supply of 400 V and a rated line current of 67.0 A. At this operating point, the shaft turns at 1475 rpm and develops a nominal torque of 238.0 Nm. These values apply at a mains frequency of 50 Hz, so an external inverter is required when variable-speed operation is needed. A delta winding connection applies the full line voltage across each motor phase. The frame accommodates the resulting magnetic flux density without auxiliary cooling.

Efficiency reaches 0.93 at full load, reducing heat losses and energy consumption compared with older IE1 designs. During short transients, the shaft can deliver up to 547.0 Nm, while the stator can accept surge currents of 167.5 A without exceeding insulation limits. A power factor of 0.86 minimizes reactive demand on the supply transformer. The rotor has an inertia of 0.483 kg·m², which moderates acceleration spikes when the motor is paired with high-ratio gearboxes. The housing weighs 305.0 kg, providing enough mass to damp vibration during operation. Sound pressure is limited to 68 dB(A), helping the machine floor remain within typical occupational noise guidelines.
