System compatibility
1AD160L-B302-4A111-S02 belongs to Rexroth Indramat 1AD spindle motor family,matched with IndraDrive series spindle servo drives.Widely applied in CNC machining center,milling machine and heavy-duty automation production lines.This is a discontinued legacy spare part for equipment maintenance replacement.
Function
1AD160L-B302-4A111-S02 is Rexroth Indramat high power asynchronous AC spindle motor.It converts three-phase electric energy into rotary mechanical power for machine tool spindle cutting processing.The 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-power operation.It acts as high power motion execution component for CNC machine tool spindle system.
Installation
Mount 1AD160L-B302-4A111-S02 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,shock and vibration resistant,stable performance under heavy cutting workshop environment.
Feature
1AD160L-B302-4A111-S02 is obsolete Rexroth spare part.Typical faults:bearing wear and abnormal noise,encoder damage,winding insulation aging,fan fault.Inspect winding,encoder and cooling system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:High power spindle rotary output,real-time speed feedback,winding temperature monitoring,used as Rexroth Indramat CNC spindle motion system spare replacement.
Product Brief
1AD160L-B302-4A111-S02 is Rexroth Indramat old 1AD high power asynchronous spindle motor for heavy-duty CNC machining center.Confirm drive compatibility,mechanical mounting and cooling configuration before ordering.ESD protection required during handling and installation.
