MOTEUR SERVO MITSUBISHI HG-SR352BJK

Description

Engineered for high-dynamic positioning tasks within industrial automation architectures, the Mitsubishi Electric HG-SR352BJK AC Servo Motor delivers high torque density and exceptional rotational stability. As part of the premium MELSERVO-J4 family, this medium-inertia motor is tailored to handle high-load fluctuations and demanding duty cycles while maintaining exceptional path accuracy. Equipped with an integrated electromagnetic holding brake and a high-resolution absolute encoder, the unit ensures reliable holding torque and micro-step precision directly out of the box.

Features

• Medium-Inertia Rotor: Optimizes feedback loop stability when handling volatile mechanical loads or high load-to-rotor inertia ratios.
• High-Resolution Feedback: Employs a 22-bit absolute/incremental optical encoder, providing 4,194,304 pulses per revolution for smooth low-speed performance and precise positioning.
• Built-in Electromagnetic Brake: Provides robust holding torque to prevent gravity-induced axis drop or accidental movement during de-energized states.
• Industrial Protection: Features a fully enclosed, self-cooling structure rated at IP67, preventing liquid ingress and particulate contamination in hostile environments.
• Integrated Keyway and Oil Seal: Shaft configuration includes a keyway with an oil seal for secure mechanical power transmission and protection against gearbox lubricant migration.

Applications

• Multi-axis gantry systems and material handling transfer lines.
• High-speed industrial packaging, wrapping, and labeling systems.
• Metalworking machine tool feed axes and positioning tables.
• Textile machinery and material winding/unwinding controls.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-SR352BJK is a drop-in replacement for equivalent legacy HC-SFS series medium-inertia motors when upgrading systems to the MR-J4 platform. When transitioning from HC series, verify parameters using MR Configurator2 to ensure the torque curves and inertia matching match your application's mechanical load profile.

Application Pitfalls & Engineering Notes

Avoid using the integrated electromagnetic brake as a dynamic braking mechanism. This component is specifically designed as a static holding brake; active deceleration using the brake will cause thermal fatigue and mechanical failure. Ensure that deceleration is handled regeneratively via the paired MR-J4-350A/B servo amplifier before engaging the brake.

Commissioning & Wiring Tips

To prevent encoder communication faults, utilize only genuine, double-shielded Mitsubishi feedback cables. The high-frequency carrier signal from the servo drive can couple noise into parallel-routed communication wires. Maintain a minimum separation of 30 cm between encoder lines and standard three-phase AC power cables.
