HG-SN202J-S100 | Mitsubishi Electric | Moteur servo

Description

Delivering precise motion control in high-inertia industrial environments, the Mitsubishi Electric HG-SN202J-S100 AC servo motor provides a rated output of 2.0 kW and comes equipped with a factory-installed oil seal. This motor is engineered to operate seamlessly with matching MELSERVO-JE amplifiers, offering dynamic response and robust protection under challenging factory conditions. Its totally enclosed, naturally cooled design ensures long-term reliability in demanding automated applications.

Features

• High-Inertia Design: Well-suited for heavy-load operations, providing stable speed control and high-accuracy positioning.
• IP67 Environmental Protection: The dust-tight and water-resistant enclosure is designed for wet or dirty manufacturing bays.
• Integrated Oil Seal: Provides robust protection against gear oil and cutting fluid migration along the motor shaft.
• Optimized Thermal Performance: Built with Class 155 (F) insulation to withstand continuous cycle-duty heat generation without degradation.

Applications

• Heavy-duty gantry axes and automated transfer systems.
• Material handling conveyors, lifters, and packaging equipment.
• Tension-control machinery, wire-drawing systems, and winders.

Empirical Engineering Insights

Alternative Models & Compatibility

The HG-SN202J-S100 is engineered specifically for pairing with the MR-JE-200A and MR-JE-200B servo amplifiers. When replacing older HC-SFS series motors, confirm the shaft dimensions and encoder connector style, as the newer HG-SN series utilizes different termination plugs. Additionally, ensure the controller firmware is updated to recognize the 131072 pulses/rev incremental encoder built into this motor.

Application Pitfalls & Engineering Notes

Although this unit is rated at IP67, the shaft passage is not fully waterproof. Overlooking the application of an appropriate gear-box seal or failing to maintain a downward-facing cable orientation can allow oil or moisture to collect at the shaft interface and eventually breach the motor housing. For continuous S1 duty cycles in enclosed control cabinets, ensure the mounting plate has a minimum surface area equivalent to a 400mm x 400mm x 12mm aluminum plate to serve as an adequate heat sink.

Commissioning & Wiring Tips

When wiring the HG-SN202J-S100, ensure you do not run encoder cables in the exact same conduit or wire duct as high-voltage motor power lines. Electromagnetic interference (EMI) can corrupt encoder feedback signals and trigger amplifier fault codes. It is highly recommended to use genuine, shielded Mitsubishi cable assemblies with correct grounding brackets. If the motor is mounted vertically, form a drip loop in the cables to prevent liquids from running down to the connectors.
