MOOG SM3420D-OC2 Servo Motor With 27.1 In-lb Continuous Torque 4500 No-load Speed

1. Product Overview

MOOG SM3420D‑OC2 is a NEMA34 frame SmartMotor™ integrated brushless DC servo motor manufactured by Moog Animatics. It consolidates brushless motor, high‑resolution encoder, power amplifier, motion controller and built‑in digital I/O within one compact housing. The OC2 variant provides enhanced circular connector output for harsh‑condition wiring. It delivers 27.1 In‑lb continuous torque and 4500 RPM no‑load speed. It executes closed‑loop position, velocity and torque control without an external separate servo drive, acting as high‑torque motion actuator for heavy‑load industrial automation equipment.

2. Product Advantages
