Product Description:

The MOT-FC-ET2-B35-225S-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 converts electrical energy from a 400 V supply into mechanical rotation for driving pumps, fans, conveyors, and other equipment that requires continuous operation near 1,500 rpm. The squirrel-cage rotor provides a durable design with few wear components, while the delta-connected stator winding supports operation with compatible low-voltage switchgear. Paired bearings support the rotor and help maintain stable shaft alignment under general-purpose industrial loads.

The motor provides a mechanical output of 37.00 kW from a 50 Hz electrical supply. During rated operation, the shaft turns at 1475 rpm and develops 238.0 Nm of torque while drawing 67.0 A from the line. Its full-load efficiency is 0.93, which limits energy losses and reduces the amount of heat generated inside the housing. The motor uses 6313/C3 and 6312/C3 CIB bearings with increased internal clearance to accommodate thermal expansion during sustained operation. Two pole pairs establish the operating speed in relation to the supply frequency, while the squirrel-cage rotor interacts with the rotating stator field to produce shaft torque. A power factor of 0.86 helps limit reactive current in the electrical distribution system.

The motor can withstand a maximum torque of 547.0 Nm during transient loading without stalling. Its rotor inertia is 0.483 kg·m², permitting moderate acceleration and deceleration while supporting manageable control response. The motor has a mass of 305.0 kg, which must be considered when selecting lifting equipment, foundations, and structural supports. Its B35 mounting arrangement combines feet with a flange, allowing the housing to be secured to a base while the shaft is aligned with directly coupled equipment. The sound pressure level is 68 dB(A) under free-field measurement conditions, providing a clear reference for installation planning. The balanced electromagnetic design also helps keep vibration within applicable IEC limits during continuous operation.
