It delivers 0.16 N·m of continuous rated torque at 3000 rpm, with a peak of 0.56 N·m available for acceleration moves. The 22-bit absolute/incremental encoder (4194304 pulses/rev) gives you position feedback fine enough for most pick-and-place and indexing applications without needing a separate feedback cable run. The 0.9 A rated current and 3.2 A peak current tell you the amplifier sizing: pair this motor with a MR-J4-10A1 or MR-J4-10A1-RJ servo drive. The IP65 all-enclosed self-cooled construction means the motor body and encoder survive washdown spray — no extra cover needed on a food-grade conveyor or a coolant-drenched machine tool axis. The 17× or less recommended load-to-motor inertia ratio is the practical limit for stable tuning; exceed it and you'll fight gain settings at startup. ## Encoder and feedback detail The 22-bit encoder is shared between absolute and incremental modes — one device, no extra wiring for multi-turn position retention. That 4194304 pulses/rev resolution gives you sub-arc-minute positioning at the motor shaft; paired with a 10:1 or 20:1 gearbox, it resolves down to a few arc-seconds at the load. Vibration resistance rated at 49 m/s² on X and Y axes — typical for a machine-tool spindle or high-speed pick head.","metaTitle":"Mitsubishi HG-KR053 MELSERVO-J4 Servo Motor, 100V, 0.16 N·m","metaDescription":"Mitsubishi HG-KR053 MELSERVO-J4 servo motor, 100V class, 0.16 N·m rated torque, 0.9 A rated current, IP65, 22-bit encoder.
