Description
Bosch Rexroth Indramat 2AD160B-B350R2-BS03-D2N1, 2AD Series Asynchronous AC Servo Motor
Core Product Overview
2AD160B-B350R2-BS03-D2N1 belongs to Rexroth Indramat 2AD series high-performance asynchronous AC servo motor. It is a closed-loop vector controlled induction motor, equipped with high-resolution encoder feedback and built-in electric holding brake, matched with Rexroth Indramat digital servo drives. It adopts independent axial forced cooling fan design, continuous high torque output, suitable for machine tools, heavy-duty automation, packaging and material handling equipment. This is a servo motor, different from Honeywell DCS / SIS rack cards and Yokogawa CENTUM controllers.

Professional Quality Control & Testing Standard Operating Procedures
All surplus and refurbished 2AD160B-B350R2-BS03-D2N1 motors follow this inspection workflow:
- Visual Inspection: Check motor housing, flange, shaft, terminal box, brake connector, encoder connector, nameplate marking.
- Winding Resistance & Insulation Test: Measure three-phase winding balance, megger insulation resistance between winding and ground.
- Brake Function Test: Energize / de-energize holding brake, verify release and holding torque, no sticking.
- Encoder Signal Test: Connect encoder simulator, check A/B/Z phase waveform and resolution.
- No-load Run Test: Power with matched drive, run at multiple speeds, check noise, vibration, temperature rise.
- Vibration Test: Verify vibration level meets Grade R requirement.
- Thermal Soak Test: Continuous running within rated temperature range, monitor winding temperature.
- Final Cleaning & Packaging: Protect shaft, apply anti-rust oil, ESD cover for encoder port, test certificate attached.
New / Refurbished Motor Installation Guidelines
- Pre-Installation Safety: Lock out servo drive power, release stored DC bus energy, follow machine LOTO procedure.
- Mechanical Alignment: Check mounting flange and foot level, align motor and load coupling; avoid misalignment.
- Coupling & Shaft Protection: Fit coupling properly; do not hammer shaft directly.
- Cable Wiring: Separate power cable, brake cable and encoder shielded cable; shield grounded at single end, away from high-power cables.
- Drive Configuration: Upload motor parameter file to Rexroth drive, set encoder type, brake logic, limit parameters.
- Offline Functional Test: JOG motor without load, confirm rotation direction, encoder counting and brake action.
- Commissioning & Acceptance: Tune speed / position loop, test emergency stop and brake holding under load, archive motor parameters and test report.
Application Scenarios & Product Features
Typical Application Scenarios
- Heavy-duty machine tool main spindle and feed axes
- Automation production lines, packaging machinery, material handling
- Metal forming, extrusion and high-duty continuous process machinery
- Spare replacement for legacy Indramat 2AD servo systems
Core Product Features
- Forced axial blower cooling for sustained high torque at low speed
- Integrated electric holding brake for static load holding and safety stop
- High-resolution encoder for precise position and speed closed-loop control
- Combined flange and foot mounting for flexible mechanical integration
- Balanced keyed shaft, suitable for direct coupling to gearboxes and loads
- Requires matched Rexroth Indramat servo drive; cannot run directly on mains power
- Obsolete legacy model; replacement needs drive parameter matching and mechanical dimension confirmation
Frequently Asked Questions (FAQ)
Q1: Is this a Honeywell DCS module? A1: No, it is Rexroth Indramat asynchronous servo motor, used for motion control, not process DCS/SIS rack hardware.
Q2: What is the difference between suffix R2 and O2? A2: R2 = with electric holding brake; O2 = without brake, no brake coil and brake connector. Not interchangeable without mechanical and control modification.
Q3: Can it be replaced by other 2AD160B variants directly? A3: No. Winding code, brake, feedback type and speed/torque curve must match the original drive parameter set.
Q4: What are common failure modes? A4: Winding insulation aging, holding brake friction pad wear, encoder cable or encoder head damage, bearing noise, blower fan failure.
Q5: Can I run it with third-party servo drives? A5: It can theoretically run on other drives supporting induction motor vector control, but original encoder protocol and motor curve are optimized for Indramat DDS/DKR drives; third-party use needs full re-tuning and risk assessment.
