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.

Installation Guidelines

CRITICAL WARNING:

Ensure the parent servo amplifier is completely de-energized and its internal bus charge-discharge indicator LED is fully extinguished before connecting or disconnecting motor power, brake, or encoder cables. High residual voltages pose lethal shock risks and can instantly damage the internal 22-bit absolute encoder.

Mount the motor securely to a rigid, flat metal bracket to ensure adequate conduction-based heat dissipation. Ensure free-flowing air can reach the motor body.

Carefully align the shaft with the load coupling to minimize radial and axial forces below the specified mechanical limits. Excessive misalignment degrades the bearing lifespan.

Perform a standard resistance check on the motor windings (U, V, W phases to ground) and verify correct polarity before running initial test cycles in JOG mode.

What is the function of the B, J, and K suffixes in the HG-SR352BJK model number?

The 'B' suffix designates an integrated electromagnetic holding brake. The 'J' suffix specifies a shaft-end structural configuration (typically including an oil seal), and the 'K' indicates a keyway shaft configuration.

Which servo amplifier series is recommended to run the HG-SR352BJK motor?

This motor is matched to the MELSERVO-J4 amplifier series. The specific compatible model is the 200V class MR-J4-350A, MR-J4-350B, or MR-J4-350GF (3.5 kW rating).

Can this motor be installed vertically with the shaft pointing upwards?

Yes, but if there is danger of oil, water, or coolant dripping onto the shaft, appropriate external oil/fluid-barrier measures should be taken since the IP67 rating excludes the mechanical shaft-through portion.

What is the resolution of the built-in encoder?

The motor includes a 22-bit optical encoder. This equates to 4,194,304 feedback pulses per single mechanical revolution of the servo shaft, allowing for high positioning accuracy.
