Product Details:

REXROTH ADP134C-B35OB2-DS0H-A2N2 belongs to Indramat ADP series three-phase AC asynchronous spindle motor. Frame size 134C, B35 flange-foot combined mounting configuration, DS0H digital encoder feedback interface, independent axial fan cooling structure. The suffix B2 stands for special shaft and connector variant compared with B1 version. This legacy spindle motor is discontinued, available stock are refurbished spare units for heavy-duty CNC machine tools and high-precision machining centers.

This spindle motor works with matched Rexroth Indramat digital spindle drive controller to realize closed-loop speed and orientation control. It delivers stable continuous torque output under heavy load and supports wide constant-power speed regulation range for high-speed precision cutting. Separate power cable and feedback wiring reduce electromagnetic interference generated by inverters and harsh workshop environment. This variant has no integrated electric holding brake.

The internal winding complies with Class F insulation standard, ambient operating temperature range 0~45℃. The motor housing reaches IP54 protection grade against dust and incidental coolant splash. Heavy-duty precision high-speed bearings and dynamically balanced rotor suppress torque ripple and vibration for smooth spindle operation. Combined flange-foot mounting supports flexible installation and convenient on-site replacement.

All operating parameters can be configured via Rexroth supporting 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 machining stations and heavy metal forming equipment. Typical application scenarios include main spindle drive units, spare replacement for aging Indramat ADP spindle systems and drive components for refurbished automation equipment. Automation integrators select this Rexroth motor for its air cooling design and stable DS0H encoder feedback performance.
