Product Description:

The MOT-FC-EV2-B35-225M-4-5CB-45-C3T-HOY is a squirrel-cage induction motor manufactured by Bosch Rexroth Indramat for the MOT Low Voltage Induction Motors series. In industrial automation, it converts three-phase low-voltage power into rotary motion for production machines, centrifugal pumps, and fan wheels without relying on hydraulic or pneumatic systems. The unit serves as the mechanical workhorse in packaging, machining, and general material-flow systems where reliable torque delivery is required. Its induction design supports continuous operation in applications that require stable speed under changing mechanical loads.

At its continuous operating point, the motor delivers a shaft output of 45.0 kW when supplied with 400 V three-phase power at the rated network frequency. The stator draws a rated current of 81.0 A and operates with a power factor of 0.86, indicating effective use of the incoming apparent power. Under these conditions, the rotor turns at 1475 rpm and produces a steady torque of 290.0 Nm. Electrical-to-mechanical conversion reaches an efficiency of 0.93, so only a small portion of the input energy is lost as heat. Two pole pairs establish the synchronous field speed. An A-side 6313/C3 deep-groove bearing centers the magnetic circuit, supports radial and axial loads, and helps limit vibration during operation.

Beyond the nominal operating point, the motor can supply up to 667.0 Nm of peak torque to accommodate brief periods of increased mechanical demand. The stator winding can momentarily conduct 202.5 A during sudden load changes. A rotor inertia of 0.59 kg·m² balances acceleration capability with speed stability for indexing and start-stop duties. Sound pressure at full load remains at 68 dB(A), helping the motor operate within common shop-floor noise limits. Thermal capacity within the laminated core and winding assembly allows the motor to handle short load surges while maintaining stable operation. The bearing arrangement and balanced rotor also help control vibration when the driven load changes rapidly.
