Description
Mitsubishi HG-KR43 MELSERVO-J4 Series Low-Inertia AC Servo Motor
The Mitsubishi HG-KR43 (part number 248654) is a high-performance low-inertia, small-capacity AC servo motor from the MELSERVO-J4 series. Engineered for applications demanding high precision, rapid response, and compact design, this motor delivers 400W rated output and operates at speeds up to 6000 r/min. With IP65 protection rating and a high-resolution 22-bit encoder, the HG-KR43 ensures reliable, precise positioning in harsh industrial environments.
Key Features & Benefits
  • High-Precision Motion Control: 22-bit absolute/incremental encoder (4,194,304 pulses/rev) for nanometer-level positioning accuracy
  • High Dynamic Response: Speed response frequency up to 500 Hz (2.5 kHz with advanced amplifiers) for ultra-fast start/stop cycles
  • Compact & Lightweight Design: Weighs 1.4 kg (standard) to 1.8 kg (with brake) for space-saving installation
  • Robust Construction: IP65 rated (dust-tight and protected against water jets) for harsh environments
  • High Overload Capacity: Delivers up to 350% of rated torque for stable operation during load changes
  • Energy Efficient: Optimized magnetic design reduces iron losses and heat generation
  • Seamless Integration: Compatible with MR-J4 series servo amplifiers and supports SSCNET III/H and EtherCAT protocols
