Voltage:3-phase,amplifier supply 400~480VAC

Frequency:267Hz

Pole:8 poles

Encoder:B128iA incremental encoder

Shaft:straight shaft with keyway

Brake:Built-in 24VDC electromagnetic holding brake

Insulation class:F

Protection class:IP67

Weight:5.1kg

Dimensions:140mm ×140mm ×198mm

Certification:CE

System compatibility:βiS HV high voltage series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with βiSV-HV servo amplifier,used for CNC machine medium-load vertical 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. Integrated electromagnetic holding brake locks shaft upon power loss to prevent vertical axis sliding. 400V high voltage design reduces current loss for long cable installation. Keyed straight shaft for coupling connection.

Installation:Flange mount,connect 3-phase power cable,encoder cable and brake control cable to servo amplifier.

Interface:

‑3-phase power connector

‑B128iA incremental encoder signal connector

‑24VDC brake power terminal

‑Motor housing mounting flange

‑Keyed straight output shaft

Circuit feature:Built-in permanent magnet rotor,encoder signal sampling circuit,thermal temperature detection circuit,brake coil drive circuit.

Feature:FANUC βiS high voltage compact servo motor with holding brake. Incremental encoder requires homing operation after power cycle. Brake only for static holding,not for dynamic braking. 400V high voltage version suitable for long cable transmission. Common faults:encoder damage,coil burnout,bearing wear,brake pad aging. Verify CNC controller and servo amplifier model before replacement.

Diagnostic:Motor or encoder failure triggers axis servo alarm,overload or position deviation alarm;brake malfunction leads to vertical axis drop or brake release alarm.

Built‑in function

A06B-0064-B503 βiS4/4000HV servo motor provides medium-torque high-speed precision closed-loop motion control and power-off holding function for CNC high voltage vertical feed axis. Widely used for CNC machine spare‑part replacement.

Product Brief

A06B-0064-B503 belongs to FANUC A06B servo motor spare parts family,0.75kW βiS4/4000HV high voltage motor with built-in holding brake,keyed straight shaft and B128iA incremental encoder. Verify CNC system,servo amplifier and cable compatibility before ordering. Check winding insulation,encoder,bearing and brake function during commissioning. Widely applied for CNC equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
