Description

Yaskawa JRMSI-120XBP01200 Product Description

Product Overview

The Yaskawa JRMSI-120XBP01200 is a high-performance, medium-inertia servo motor designed for industrial automation applications requiring high torque and smooth motion control. Part of Yaskawa’s Σ-7 (Sigma-7) series, this motor delivers exceptional dynamic response and precision, making it ideal for CNC machinery, robotics, and high-speed production lines.

With a rated power of 1.2kW (1200W) and optimized electromagnetic design, the JRMSI-120XBP01200 provides high torque density while minimizing energy loss. Its IP65-rated enclosure ensures durability in harsh environments, resisting dust, oil, and water ingress. The motor features a high-resolution 24-bit absolute encoder, enabling ultra-precise positioning (±1 arc-minute) and smooth operation at low speeds.

Designed for seamless integration with Yaskawa’s Σ-7 servo drives (e.g., SGD7S series), this motor supports MECHATROLINK-III/IV and EtherCAT communication, ensuring fast, synchronized motion in multi-axis systems.
