Specification

The MITSUBISHI MELSERVO-J4 SERVOMOTOR 7.5KW HG-SR702J is a cornerstone of the HG-SR 2000 r/min series, designed for medium-inertia and medium-capacity applications. Compatible with 3-phase 200 V AC systems, this servo motor combines high torque density with exceptional dynamic response. Its 22-bit absolute encoder provides sub-micron-level feedback, making it ideal for CNC machining, packaging, and robotic systems. The motor’s compact frame and optimized electromagnetic design minimize cogging and torque ripple, ensuring smooth operation even at low speeds. Below is the comprehensive technical specification table for the HG-SR702J and related models.
