Product Name: 17M203A-31 — Goldline M-203 Series Metric Frame Servo Motor with Commutation / Tachology Feedback
-
Product Introduction: This is a legacy Goldline M-203 medium-inertia servo motor in metric configuration, typically shipped with integral tachometer generator and/or encoder (suffix “-31” defines feedback combination — often tach + resolver or tach + encoder). Used with BDS5 or SERVOSTAR amplifiers.
