Product Details:

REXROTH 2AD180C-B35OB1-BS03-B2N1 belongs to Indramat 2AD series three-phase AC asynchronous spindle motor. Frame size 180C, B35 flange-foot combined mounting configuration, BS03 high-resolution digital encoder feedback interface, independent axial blower cooling structure. This legacy spindle motor is discontinued, available stock are refurbished spare units for heavy-duty CNC machine tools and high-torque nutrunner tightening spindles.

This spindle motor works with matched Rexroth digital 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 for high-speed precision machining. 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, ambient operating temperature range 0~45℃. The motor housing reaches IP65 protection grade against dust and incidental coolant splash. Heavy-duty precision bearings and dynamically balanced rotor suppress torque ripple and vibration for smooth high-speed spindle operation. Combined flange-foot mounting supports flexible installation 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 endurance test and vibration grade test to guarantee reliable performance for long-time multi-shift industrial production.

It is widely used on large CNC machining centers, automotive powertrain bolt fastening stations and heavy 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 BS03 encoder feedback and high-power heavy-load performance.
