HG-SR352 | Mitsubishi Electric | Servomotor Serie HG-SR

Description

Designed for medium-inertia industrial applications requiring precise motion control, the Mitsubishi Electric HG-SR352 is a high-performance AC rotary servo motor within the MELSERVO-J4 family. This motor balances a robust torque-to-weight ratio with a rugged construction, making it highly suitable for demanding operating environments. Equipped with a high-resolution absolute position encoder as standard, the HG-SR352 ensures exceptional positioning accuracy and smooth velocity control even at low speeds.

The unit features advanced magnetic design and optimized winding configurations to minimize cogging torque, facilitating high-speed response and dynamic path-following. Engineered to pair seamlessly with MR-J4 servo amplifiers, this motor supports sophisticated motion profiles and simplified commissioning through auto-tuning functions.

Features

• Medium-inertia rotor design optimized for stable, high-load acceleration and deceleration.
• Equipped with a high-resolution 22-bit absolute/incremental encoder (4,194,304 pulses per revolution) for fine positioning control.
• Robust IP67-rated protective structure (excluding the shaft-through portion) to safeguard against dust and water ingress.
• Low-cogging torque characteristic ensures consistent, vibration-free rotation.
• Reliable terminal design for secure power and encoder connections in high-vibration environments.

Applications

• Material handling systems and transfer gantries
• Packaging, wrapping, and labeling machinery
• Automated assembly lines and pick-and-place robots
• Injection molding machines and metal forming presses
• Textile manufacturing equipment

Installation Guidelines

• Mounting: Ensure the mounting flange is securely bolted to a rigid, vibration-resistant machine frame to prevent misalignment.
• Shaft Alignment: Use a flexible coupling for direct shaft connections. Do not exceed permissible radial and thrust load limits during installation.
• Cable Routing: Avoid applying excessive stress, sharp bends, or tension to the power and encoder cables. Ensure the cable connectors are fully locked to maintain the IP67 sealing rating.
• Thermal Management: Maintain adequate ventilation clearance around the motor body. Mount the motor on a heat-conductive metal surface to assist with passive cooling.
• Grounding: Ensure the motor frame is grounded through the protective earth (PE) terminal to mitigate electromagnetic interference and ensure operator safety.

Compliance and Certifications

• CE (LVD and EMC Directives)
