Product Description:

The MOT-FC-ET2-B35-180L-4-5CB-22-C3T-HOY is a three-phase squirrel-cage induction motor manufactured by Bosch Rexroth Indramat and supplied within the MOT Low Voltage Induction Motors series. This frame size 180 motor is intended for general-purpose drive duties in conveying, pumping, and fan assemblies where constant-speed operation is required. By converting electrical energy from the plant supply into mechanical rotation, the motor provides the primary actuation element in automated production cells.

Its nameplate assigns a continuous mechanical output of 22.0 kW when the stator is fed with a line-to-line voltage of 400 V at 50 Hz. Under these conditions, the rotor reaches a slip speed close to 1470 rpm, matching four-pole operation with two pole pairs. Full-load efficiency is 0.90, so about 90% of the electrical input appears as shaft power while the remainder is dissipated as heat. A displacement power factor of 0.86 indicates a moderate phase difference between current and voltage. The delta winding connection supports line starting through standard contactors, and double-shielded 6311-ZZ/C3 bearings support the shaft while limiting lubrication intervals. Sound pressure is specified at 66 dB(A), keeping acoustic output within typical factory limits.

The motor delivers a rated torque of 143.0 Nm, enabling direct coupling to medium-inertia loads without gear reduction. For acceleration peaks or transient disturbances, the electromagnetic system can deliver up to 372.0 Nm, so brief overloads are less likely to stall the rotor. Thermal and magnetic limits correspond to a rated current of 41.0 A, while the stator can draw as much as 102.5 A during startup or severe load steps. With a rotor inertia of 0.173 kg·m², the machine shows moderate dynamic response and can maintain stable speed control when paired with a soft starter or VFD. The pole-pair configuration fixes synchronous speed at 1500 rpm on a 50 Hz supply, so nominal slip remains low and losses stay controlled.
