Product Details:

REXROTH 2AD160B-B05OA1-BS26-H2N1 belongs to Indramat 2AD series three-phase AC asynchronous spindle motor. Frame size 160B, B05 flange mounting, BS26 digital encoder feedback interface, axial blower cooling structure, operating ambient temperature range 0~45℃. This legacy spindle motor is discontinued, available stock are refurbished spare units for CNC machine tools and heavy-duty nutrunner tightening spindles.

This spindle motor pairs with matched Rexroth drive controller to realize closed-loop speed and position control. It delivers stable continuous torque output under heavy load and supports wide constant-power speed regulation range. Separate power cable and feedback wiring reduce electromagnetic interference generated by inverters and harsh workshop environment. It is a standalone motor without integrated holding brake.

The internal winding complies with Class F insulation standard. The motor housing reaches IP54 protection grade against dust and incidental coolant splash. Heavy-duty precision bearings and dynamically balanced rotor suppress torque ripple and vibration for stable high-speed spindle running. Standard flange interface supports modular assembly and convenient on-site replacement.

All operating parameters can be configured via Rexroth engineering software. Each unit passes factory inspection including insulation resistance test, speed stability test, cyclic load test and vibration endurance test for reliable long-time multi-shift industrial operation.

It is widely used on CNC machining centers, automotive powertrain bolt fastening stations and metal forming equipment. Typical application scenarios include main spindle drive units, spare replacement motors for aging Indramat systems and drive components for refurbished automation equipment. Automation integrators select this Rexroth motor for its stable BS26 encoder feedback and high-power dynamic performance.
