Description

Designed for high-precision industrial motion control, the HG-SR102-K(B) is a medium-inertia AC rotary servo motor engineered by Mitsubishi Electric as part of the highly reliable MELSERVO MR-J4 series. This high-performance motor delivers a rated output of 1.0 kW and is optimized for heavy-duty industrial applications requiring robust torque stability and accurate positioning. Built to withstand demanding factory environments, this unit features a robust keyway shaft configuration for secure mechanical connection alongside an integrated electromagnetic brake designed to secure loads during power loss.

The HG-SR102-K(B) functions seamlessly with compatible MELSERVO MR-J4 series servo amplifiers, leveraging high-resolution encoder technology to ensure closed-loop feedback and minimal speed fluctuation. The design emphasizes thermal efficiency and durability, making it an excellent fit for dynamic machinery setups where reliability and operational uptime are critical.

Features

  • Medium-inertia design optimal for stable control of high-load mechanical systems.
  • Integrated electromagnetic holding brake for enhanced safety and position-holding during power-down states.
  • Standard keyway shaft configuration ensuring secure mechanical torque transmission without slippage.
  • High-resolution encoder integration for exceptional positioning accuracy and minimal velocity ripple.
  • Industrial-grade winding insulation and IP-rated construction protecting internal components from debris.

Applications

  • Material handling systems, packaging lines, and high-speed conveyors.
  • CNC machine tools, textile machinery, and printing presses.
  • Robotic gantry systems and multi-axis positioners.
  • Automated assembly systems and metal forming equipment.

Installation Guidelines

  • Shaft Alignment: Ensure precise coupling alignment between the keyway shaft and the driven machinery to prevent excess radial or axial forces on the motor bearings.
  • Thermal Management: Maintain unobstructed airflow around the motor body to ensure the ambient temperature does not exceed 40 degC during continuous operation.
  • Brake Wiring: Connect the electromagnetic holding brake to a dedicated, surge-protected control circuit. Do not use the holding brake for dynamic deceleration or stopping.
  • Cable Routing: Separately route the power and feedback cables to mitigate electromagnetic interference (EMI) and ensure reliable signal transmission.
