HG-SR352J | Mitsubishi Electric | Moteur servo AC

Description

Engineered for high-performance industrial motion control, the Mitsubishi Electric HG-SR352J is a medium-inertia, high-capacity rotary AC servo motor designed to deliver precise speed and position control. This 3.5 kW motor is part of the respected HG-SR Series and is commonly paired with compatible MELSERVO servo amplifiers to manage demanding dynamic loads. Featuring an integrated oil seal (indicated by the "J" suffix), the unit is highly suited for industrial environments where protection against lubricant and fluid ingress is critical.

The rugged electromechanical construction ensures reliable operation under continuous-duty cycles. With its medium-inertia characteristics, the motor provides an optimal balance between torque output and load-matching capability, making it highly effective for heavy-duty positioning tasks in automated machinery.

Features

• Medium-inertia rotor design optimizes load-to-motor inertia matching for stable velocity control.
• Integrated factory-installed oil seal protects internal motor components from liquid ingress.
• Class 155 (F) insulation ensures high thermal resilience under peak loading conditions.
• Low-vibration execution (Vibration Rank V10) minimizes mechanical wear on connected gearboxes and couplings.
• Brushless AC design reduces maintenance overhead and extends operational lifespan.

Applications

• Material handling systems and heavy-duty transfer gantry axes.
• CNC machine tools and metalworking feed axes.
• Automated packaging machinery and continuous film-feeding lines.
• Textile processing machines.
• Multi-axis robotic positioners and industrial rotary tables.

Installation Guidelines

• Shaft Alignment: Ensure precise alignment with the driven shaft during installation. Excessive radial or axial loads beyond rated limits can lead to premature bearing failure.
• Environmental Protection: Mount the motor indoors in an environment shielded from direct sunlight. The installation site must be free from corrosive gases, flammable gases, and highly concentrated dust or dirt.
• Wiring and Grounding: Connect the power and encoder cables using official Mitsubishi standard connectors. Ensure the motor frame is securely grounded to the control panel's protective earth (PE) bus.
• Thermal Management: Maintain adequate space around the motor frame to facilitate natural convection cooling and prevent heat concentration.
