Mitsubishi Electric HG-SR201J MELSERVO MR-J4 Medium Inertia Small Capacity Servo Motor

Description

Designed to provide highly stable driving dynamics for medium-capacity systems, the Mitsubishi Electric HG-SR201J is a high-performance rotary servo motor within the popular MELSERVO MR-J4 product family. This unit features a medium inertia design, optimizing it for applications requiring robust load matching and precise motion control without excessive resonance or hunting. Operating at a rated output of 2.0 kW, the HG-SR201J servo motor delivers reliable torque stability at a rated speed of 1000 r/min. It is configured with a standard straight shaft end and does not include an integrated electromagnetic brake, making it suitable for continuous-duty cycles where free-rotation on power-down is preferred.

Features

• Medium-inertia rotor design minimizes tuning issues with high-inertia loads.
• High-resolution absolute encoder compatibility for precision positioning and feedback.
• Inherent protective construction rated at IP67, excluding the shaft pass-through.
• Engineered for seamless integration with MELSERVO MR-J4-A and MR-J4-B servo amplifiers.
• Robust thermal design with high dissipation efficiency to prevent overheating.

Applications

• Material handling and transfer systems
• Industrial gantry systems and Cartesian robots
• Packaging machinery and continuous feeders
• Textile processing equipment
• Machine tool feed axes

Installation Guidelines

• Mounting: Secure the motor firmly to a metallic machine base to ensure adequate heat dissipation and alignment stability.
• Alignment: Use a high-quality flexible coupling and verify alignment between the motor shaft and the load shaft to prevent excessive bearing loads and vibration.
• Environmental Limits: Install in an environment free of corrosive gases, flammable gases, and excessive oil mist. Ambient operating temperature must be maintained within 0 to 40 degC.
• Wiring: Route power cables and encoder cables separately to minimize electromagnetic interference (EMI). Ensure the motor housing is securely grounded using the designated grounding terminal.

Compliance and Certifications

• CE Mark
• UL/cUL Recognized
• RoHS Directive Compliant
