Product Description:

The Bosch Rexroth 2AD160B-B35RR2-BS03-B2N3/S028 Servo Motor features a flange mounting construction. Its construction supports continuous duty cycles in harsh industrial applications. The asynchronous design allows robust torque performance across a wide range of speeds.

The 2AD160B-B35RR2-BS03-B2N3/S028 servo motor comes with an axial blower that ensures efficient cooling. The air flows is from side A to B for continuous operation. It provides a nominal power output of 37 kW and operates at a nominal voltage of 299 V. The insulation system meets class F standards which supports a higher temperature tolerance for extended motor life. The rotor moment of inertia is 0.229 kg·m² that is suitable for dynamic load changes with precise control. The noise level at 1 meter under PWM of 4 kHz is 75 ± 3 dB (A). The power connection is directed to side A through a terminal box layout that ensures organized wiring. The motor is dynamically balanced according in balance class R (reduced) that minimizes vibration and enhancing operational smoothness. The connector (motor feedback) is designed as a flanged socket for easy electrical integration in automation systems. The placement of the feedback connection allows easy access for diagnostics and service. This motor is engineered to perform in environments where precision, thermal control and vibration suppression are essential.

A built-in NTC thermistor is embedded in the 2AD160B-B35RR2-BS03-B2N3/S028 servo motor windings to monitor and protect against overheating. The drive system monitors the thermistor values and will shut down the motor if it exceeds safe temperature limits. An error message is generated during such events that alerts the user to take action. This thermal protection mechanism is integrated into the motor’s power connection for seamless operation.

Frequently Asked Questions about 2AD160B-B35RR2-BS03-B2N3/S028:

Q: What design aspect of the 2AD160B-B35RR2-BS03-B2N3/S028 ensures high thermal endurance in harsh duty cycles?

A: It features a Class F insulation system rated for high-temperature environments. This improves longevity and maintains insulation integrity under prolonged thermal stress.

Q: How does the Bosch Rexroth 2AD160B-B35RR2-BS03-B2N3/S028 maintain efficient cooling in non-stop operation?

A: An axial blower directs airflow from side A to B for active cooling. This ensures consistent thermal regulation during continuous industrial loads.

Q: How is overtemperature protection implemented in this asynchronous servo motor?

A: The motor integrates an NTC thermistor in the windings. It triggers shutdown and alerts when unsafe temperatures are detected by the drive system.

Q: What mechanical feature supports smooth performance in variable load automation?

A: It uses dynamic balancing in class R (reduced). This reduces shaft vibration, improving control precision and mechanical reliability across varying torque demands.

Q: How does the motor simplify feedback and service diagnostics in dense electrical panels?

A: Its flanged feedback connector is co-located with the power terminal. This compact layout improves accessibility during commissioning and troubleshooting.
