Mitsubishi Electric HG-SN202BJ-S100 HG-SN Serie Servomotor

Description

Designed for precise industrial motion control, the HG-SN202BJ-S100 is a high-performance AC servo motor within the Mitsubishi Electric HG-SN series. This motor delivers a nominal rated output of 2.0 kW and operates at a base rated speed of 2000 r/min. To handle demanding environmental conditions and vertical axis safety, the motor is equipped with an integrated electromagnetic brake and a factory-installed oil seal, ensuring reliable holding torque and protection against fluid ingress.

The unit features a totally enclosed, naturally cooled design with an IP67 protection rating (excluding the shaft-through portion). It is engineered for low-inertia load matching, offering stable torque output up to a maximum speed of 3000 r/min. This motor integrates seamlessly into automation architectures using compatible MELSERVO drive units, providing high dynamic response and absolute positioning reliability.

Features

• Electromagnetic Brake: Built-in safety brake for secure holding during power loss or emergency stop sequences.
• Oil Seal Protection: Factory-installed oil seal (J-type) prevents fluid and lubricant ingress at the shaft interface.
• High Environmental Resistance: Totally enclosed, natural cooling system rated to IP67.
• Vibration Resistance: Rated at vibration rank V10, minimizing rotational noise and mechanical wear.
• Optimized Inertia Ratio: Recommended load to motor inertia ratio of 15 times or less for precise servo tuning.

Applications

• Vertical axis axes in CNC machinery and gantry systems requiring fail-safe braking.
• Material handling and automated warehouse transfer systems.
• Food processing and packaging machinery exposed to light washdown or moisture.
• Textile, printing, and paper converting machinery demanding constant tension and speed control.

Technical Specifications

Installation Guidelines

• Shaft Alignment: Ensure precise concentric alignment when coupling the motor shaft to the load to prevent premature bearing wear.
• Brake Control Wiring: Wire the electromagnetic brake using a dedicated, surge-protected 24V DC power line separate from the main motor power supply.
• Cooling Clearance: Mount the motor with sufficient clearance around the frame to allow natural convection cooling.
• Grounding: Ensure the motor frame is grounded via the grounding terminal in the power connector before applying control power.
