HG-SR421 | Mitsubishi | Moteurs servo AC

Description

Designed to deliver high performance in medium-inertia industrial positioning systems, the HG-SR421 AC servo motor offers stable motion control for heavy-duty automation environments. This rotary servo motor operates within the MELSERVO system architecture, providing exceptional torque density and precise positioning feedback. Engineered with high-resolution encoder technology, it enables smooth operation and accurate speed regulation under varying load conditions.

The robust IP67-rated enclosure ensures protection against dust and moisture ingress, making it suitable for demanding industrial installation sites. Utilizing high-performance permanent magnets, this motor achieves a continuous rated output of 4200 W, balancing thermal efficiency with high dynamic responsiveness.

Features

• Medium-inertia design optimized for stable load control in heavy mechanical systems.
• High-resolution absolute encoder integration for precise feedback and positioning.
• Robust environmental protection rating for reliable deployment in harsh industrial conditions.
• Low-cogging design for uniform rotation even at low operating speeds.
• Compatible with MELSERVO-MR-J4 servo amplifiers.

Applications

• Metalworking and machine tool axes.
• Heavy material handling and gantry transfer systems.
• Large-scale packaging and printing machinery.
• Industrial robot positioners and external axes.

Installation Guidelines

• Mounting Alignment: Ensure precise alignment between the motor shaft and the driven load. Misalignment exceeding specifications can damage the coupling, motor bearings, or shaft.
• Environmental Protection: While rated IP67, protect the motor from continuous exposure to liquids and avoid submerging. Ensure the cable connectors are correctly sealed and locked.
• Thermal Management: Provide adequate ventilation space around the motor frame to facilitate natural convection cooling. Do not block the heat-dissipating surfaces.
• Wiring: Ground the motor frame to the protective earth terminal of the servo amplifier to suppress electromagnetic interference (EMI) and prevent electrical hazards.
