It delivers 0.64 N·m rated torque and 2.2 N·m maximum torque, with a rated speed of 3000 rpm and a maximum of 6000 rpm. The motor is IP65-rated (all enclosed self-cooled), meaning it handles splash and dust ingress — suitable for machine-tool spindles, pick-and-place axes, and packaging lines where washdown or debris is present. It carries a 22-bit absolute/incremental shared encoder (4194304 pulses/rev), giving fine position feedback for closed-loop servo control without needing a home cycle on power-up. ## Load and mechanical limits The recommended load-to-motor inertia ratio is 26 times or less (motor inertia 0.243×10⁻⁴ kg·m²), which guides coupling selection — exceeding that ratio risks instability at high gains. Allowable radial load on the shaft is 245 N, thrust load 98 N. These are the bearing limits; a direct-coupled load that exceeds them needs a separate bearing support. Instantaneous allowable speed is 6900 rpm — a 15% overshoot margin above the 6000 rpm max operating speed, useful for brief transient moves. ## Environmental and installation Ambient operating temperature range is 0 °C to 40 °C, with storage from -15 °C to 70 °C. Humidity must stay under 80% RH (non-condensing) during operation, 90% RH storage. The motor is rated for installation indoors, no direct sunlight, and in atmospheres free of corrosive gas, flammable gas, oil mist, and excessive dust. Elevation limit is 2000 m above sea level. Vibration resistance is specified at X: 49 m/s², Y: 49 m/s² (V10 class), which covers most machine-tool and general automation environments without additional damping. ## Interface and drive compatibility The HG-KR23B can be paired with multiple drive interface options: CC-Link IE Field Network, SSCNET/H, 2-axis or 3-axis integrated SSCNET/H, or general-purpose interface — choose the MR-J4 drive variant that matches your network topology. Rated current draw is 1.3 A, maximum 4.6 A. The recommended power supply capacity is 0.5 kVA. These numbers drive the sizing of the servo drive and upstream cabling. Overseas compliance documentation (international standards and laws) is referenced in the manufacturer's Standards Compliant page — consult that for specific UL, CE, or other regional marks.","metaTitle":"Mitsubishi HG-KR23B MELSERVO-J4 Servo Motor, 0.2 kW, 3000 rp","metaDescription":"Mitsubishi HG-KR23B servo motor from MELSERVO-J4 series. 0.2 kW rated output, 0.64 N·m rated torque, 3000 rpm, IP65.
