The Mitsubishi HG-KN43J-S100 is a 400 W servo motor from the MR-JE series, built for positioning and speed control in automated machinery. It delivers 1.3 Nm of rated torque at 3000 r/min, with a peak torque of 3.8 Nm available up to 5000 r/min for short-duration acceleration or deceleration moves. The 17-bit encoder provides absolute position feedback on power-up, so homing sequences are unnecessary on each cycle — a practical advantage for pick-and-place or shuttle applications where the axis must know its position immediately after a power loss.
