Its 0.8 A rated current and 0.32 N·m rated torque suit light-duty positioning axes — think pick-and-place, small conveyors, or tool changers. The 22-bit absolute encoder (4194304 pulses/rev) gives you position hold through power cycles without a home search, which saves a cycle on every startup. IP65 all-enclosed self-cooled construction means the motor body handles washdown and dust ingress — fine for food packaging or machining coolant splash, as long as the shaft extension isn't directly hosed. The oil seal is listed as None, but a variant with an oil seal (HG-KR_J) is available if you need shaft sealing against oil mist. ## Integration notes The motor mates with MR-J4-10A-RJ (general-purpose) or MR-J4-10B-RJ (SSCNET/H) servo amplifiers. The 22-bit encoder is compatible with both interfaces; no separate battery unit needed for absolute position retention if the amplifier supplies backup power. Rated speed 3000 rpm, max 6000 rpm — the 6900 rpm instantaneous limit is the hard stop for overspeed faults. Recommended load inertia ratio is 17 times or less; moment of inertia is 0.0837 × 10⁻⁴ kg·m². Keep the reflected load inertia within that ratio to avoid tuning headaches and resonance. The regenerative braking frequency of 1350 times/min applies when paired with MR-J4W_ series amplifiers — relevant for high-cycle indexing.","metaTitle":"Mitsubishi HG-KR13B Servo Motor 100W, MELSERVO-J4, 0.8 A, IP","metaDescription":"Mitsubishi HG-KR13B MELSERVO-J4 servo motor, 100W, 0.8 A rated, 0.32 N·m torque, IP65, 22-bit encoder.
