Product Description:

Bosch Rexroth Indramat manufactures the ADS112C-B05TB1-ASF3-N2S5. The motor belongs to the ADS Servo Motors series and is engineered as a three-phase induction drive for spindle and positioning duties in automated production lines. By delivering controlled rotary motion directly from electrical input, it links the machine controller to mechanical tooling and supports repeatable, high-throughput cutting, drilling, or transfer operations. Its design emphasizes efficient conversion of plant power to shaft torque while keeping thermal loads manageable during continuous service.

During nominal operation, the shaft turns at 3000 rpm and produces a continuous torque of 64 Nm. At this operating point, the stator draws 58 A from a three-phase supply rated at 380 V and converts it into a mechanical output of 20 kW. Electrical and magnetic losses add up to 4.0 kW of heat, which must be removed by a coolant flow of at least 5.4 L/min. The cooling circuit can tolerate a closed-circuit pressure of 3 bar, while the sealing-air connection can be loaded to 1.5 bar to help prevent ingress. The drive and its matching inverter must accommodate this electrical and thermal load when the axis runs for extended periods at rated speed.

Above the continuous operating point, the design permits acceleration to a peak of 18000 rpm for short bursts, provided the coolant limits the temperature increase to 10 K. Vibration is capped at 1.8 mm/s to protect the bearings, and the enclosure carries an ingress rating of IP54, which blocks dust and water spray from reaching live components. A rotor inertia of 0.0267 kgm² balances quick speed changes with stable running, enabling precise positioning when the motor is paired with a high-bandwidth drive. These operating limits should be observed when the motor is integrated into high-speed machine tools or handling systems.
