The Mitsubishi HG-KR053D is a 50 W servo motor from the HG-KR series, a low-inertia, small-capacity line sized for light-axis positioning on pick-and-place, labelling, and small-conveyor stations. Rated speed sits at 3000 r/min, which is the standard speed class for this power band — the motor delivers its torque curve right up to that corner speed, so the drive tuning stays within the familiar 3 kHz velocity-loop bandwidth range.
Shaft is a D-cut profile (053/13 pattern), which mates directly to the standard Mitsubishi coupling range without an adapter bushing. No oil seal is fitted on this variant — the standard build is intended for clean, dry cabinet environments where ingress protection is handled by the enclosure, not the motor seal. No electromagnetic brake is present either, so the load must hold position through the drive's holding torque or an external brake resistor on the vertical axis.
