Nabtesco AR15-BAT Motor

The Nabtesco AR15‑BAT is a compact all‑in‑one single‑axis servo actuator that integrates the drive motor, reduction gearbox, holding brake and encoder into one flat unit. Common failure modes for this class of equipment include worn gear teeth or bearing damage, brush wear in the motor, loss of encoder resolution, and overheating of the integrated brake due to excessive duty cycle. First‑check diagnostics should verify proper 24 V/48 V power supply continuity, inspect the motor windings for shorted turns, confirm encoder signal integrity with a logic analyzer, and review any fault codes from the internal drive controller.[oss-gpt-20b]
