Product Details:

REXROTH 2AD134B-B35RL1-ES06-D2N1, MNR: R911281404, belongs to Indramat 2AD series three-phase AC asynchronous spindle motor. Frame size 134B, B35 flange-foot combined mounting, axial blower cooling, ES06 digital encoder feedback interface, rated power 18.1kW. 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 compatible Rexroth drive controller to realize closed-loop speed and position control. It maintains stable continuous torque output under heavy load and supports wide constant-power speed regulation range. Separate power and feedback wiring reduces electromagnetic interference from 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. It is equipped with heavy-duty bearings, shaft fitted with sealing ring, balanced keyway shaft design, vibration severity grade 1. Optimized rotor structure suppresses torque ripple and vibration for smooth high-speed spindle running.

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 to adapt to 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 high power rating and reliable ES06 encoder feedback.
