Description

Designed for high-inertia and high-precision motion control applications, the HG-SR702JK from Mitsubishi Electric is a robust medium-capacity rotary servo motor within the MELSERVO-J4 series. Delivering reliable performance at 200V, this high-performance industrial motor incorporates an integrated oil seal and keyway shaft to withstand rigorous operating conditions. It features a high-resolution absolute/incremental feedback system, ensuring exceptional dynamic response and position accuracy in closed-loop systems when paired with compatible MR-J4 servo amplifiers.

The motor is fully enclosed and self-cooled, achieving an IP67 environmental protection rating. Its high torque density, wide speed range, and compatibility with SSCNET III/H and CC-Link IE Field networks make it highly suitable for demanding industrial positioning systems.

Features

  • High-Resolution Feedback: Equipped with a 22-bit encoder providing 4,194,304 pulses per revolution for ultimate positioning accuracy.
  • Robust Protection: Totally enclosed, self-cooling structure with an IP67 rating and built-in oil seal for protection against dust and water ingress.
  • Dynamic Torque Output: Generates a rated torque of 33.4 N m with peak torque capability reaching up to 100 N m.
  • Flexible Connectivity: Full compatibility with MR-J4-700B, MR-J4-700B-RJ, and MR-J4-700A-RJ servo drives across fiber-optic SSCNET III/H and industrial Ethernet interfaces.

Applications

  • Heavy-duty material handling and transfer gantries
  • Metal processing and high-precision CNC machining tools
  • Packaging, labeling, and high-speed sorting systems
  • Automated assembly systems and industrial robotics

Installation Guidelines

  • Shaft Alignment: Ensure precise alignment of the keyway shaft to load coupling to prevent radial and axial forces from exceeding maximum allowable mechanical limits.
  • Thermal Management: Install the motor in areas with adequate clearance to support natural convection cooling. Avoid direct exposure to heat sources.
  • Grounding and Shielding: Use shielded power and encoder cables, ensuring appropriate grounding clamps are securely fastened to eliminate electromagnetic interference (EMI).
  • Oil Seal Protection: Verify that the oil seal is kept clean and free from abrasive particles during installation and routine maintenance.
