System compatibility

2AD100C-B050A1-AS03-B2N1 belongs to Rexroth Indramat 2AD spindle motor family,matched with IndraDrive series spindle servo drives.Widely applied in CNC machining center,milling machine and automation production lines.This is a discontinued legacy spare part for equipment maintenance replacement.

Function

2AD100C-B050A1-AS03-B2N1 is Rexroth Indramat compact AC asynchronous spindle motor.It converts three-phase electric energy into rotary mechanical power for machine tool spindle cutting processing.The digital encoder feeds back real-time rotor speed and position signal to servo drive for closed-loop speed control.The built-in temperature sensor monitors winding temperature continuously for overload protection.It adopts forced axial blower cooling structure to ensure stable continuous high-speed operation.It acts as precision motion execution component for medium CNC machine tool spindle system.

Installation

Mount 2AD100C-B050A1-AS03-B2N1 on machine spindle flange and tighten mounting bolts.Align coupling and check concentricity.Connect three-phase power cable and encoder cable according to wiring drawing.Motor blower wiring should be connected separately.Check winding insulation resistance before power-on commissioning.

Interface

‑3-phase motor power connector

‑Encoder feedback connector

‑Motor temperature sensor terminal

‑Cooling fan power port

Circuit feature

Stable squirrel-cage rotor design,wide constant power speed range,low vibration,shock resistant,stable performance under machining workshop environment.

Feature

2AD100C-B050A1-AS03-B2N1 is obsolete Rexroth spare part.Typical faults:bearing wear and abnormal noise,encoder damage,winding insulation aging,fan fault.Inspect winding,encoder and cooling system before replacement.This spindle motor must match corresponding IndraDrive servo drive,direct substitution without inspection is not recommended.

Diagnostic

When encoder damage,winding overheat or cooling fan failure occurs,the servo system will trigger alarm and stop spindle operation.

Built‑in function:Spindle rotary motion output,real-time speed feedback,winding temperature monitoring,used as Rexroth Indramat CNC spindle motion system spare replacement.

Product Brief

2AD100C-B050A1-AS03-B2N1 is Rexroth Indramat old compact 2AD asynchronous spindle motor for medium CNC machining equipment.Confirm drive compatibility,mechanical mounting and cooling configuration before ordering.ESD protection required during handling and installation.
