Product Description
MPL-B310P-HJ72AA is an Allen‑Bradley MPL series low-inertia brushless AC servo motor for Rockwell Kinetix servo drive system. It is rated for 460V three-phase AC, Frame 3 (100mm frame size), rated speed 5000RPM. It is equipped with Hiperface multi-turn high-resolution sin/cos absolute encoder and keyed shaft extension. It adopts SpeedTEC DIN right-angle rotatable quick connector, no internal brake, IEC metric FF mounting flange. With low rotor inertia for fast dynamic response, it is designed for high-precision and high-speed reciprocating motion and widely used as spare part for automation lines.
