System compatibility:βiS series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with βiSV servo amplifier,used for small CNC machine feed axes.
Function:Permanent magnet AC servo motor for CNC feed axis. Realizes closed-loop position and speed control via built-in B128iA incremental encoder. Delivers fast response for high-speed small load feed motion. Keyed straight shaft for coupling connection.
Installation:Flange mount,connect power cable and encoder cable to servo amplifier.
Interface:
‑3-phase power connector
‑B128iA incremental encoder signal connector
‑Motor housing mounting flange
‑Keyed straight output shaft
Circuit feature:Built-in permanent magnet rotor,encoder signal sampling circuit,thermal temperature detection circuit.
Feature:FANUC βiS compact high-speed servo motor,no brake design. Incremental encoder requires homing operation after power cycle. Common faults:encoder damage,coil burnout,shaft bearing wear,magnet demagnetization. Verify CNC controller and servo amplifier model before replacement.
Diagnostic:Motor or encoder failure triggers axis servo alarm,overload or position deviation alarm in CNC system.
Built‑in function
A06B-0061-B203 βiS2/4000 servo motor provides high-speed precision closed-loop motion control for small CNC machine feed axis. Widely used for CNC machine spare‑part replacement.
Product Brief
A06B-0061-B203 belongs to FANUC A06B servo motor spare parts family,0.5kW βiS2/4000 motor with keyed straight shaft and B128iA incremental encoder. Verify CNC system,servo amplifier and cable compatibility before ordering. Check winding insulation,encoder and bearing function during commissioning. Widely applied for CNC equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
