Mitsubishi HG-KR13 100W 200V AC Low-Inertia Servo Motor with 22-Bit Encoder

The Mitsubishi HG-KR13 is a compact, low-inertia servo motor developed for the MELSERVO-J4 servo system. With a rated output of 0.1 kW (100 W), it delivers 0.32 N·m rated torque and 1.1 N·m maximum torque. The motor operates at a rated speed of 3,000 r/min and reaches a maximum speed of 6,000 r/min, providing responsive rotary motion for small-capacity automation and positioning applications.

For accurate motion feedback, the HG-KR13 uses a 22-bit absolute/incremental encoder with a resolution of 4,194,304 pulses per revolution. Its low moment of inertia of 0.0777 × 10⁻⁴ kg·m² supports responsive acceleration and deceleration. The standard HG-KR13 has a straight shaft, no electromagnetic brake, and a totally enclosed, natural-cooling structure with IP65 protection, excluding the shaft-through portion.

The HG-KR13 is intended for general industrial machinery where compact size, high-resolution feedback and precise motion control are required. Mitsubishi specifically gives applications such as X-Y tables and semiconductor manufacturing equipment. The motor can also be used in compatible positioning and automation systems requiring a 100 W Mitsubishi servo motor. When replacing an existing motor, the exact model, servo amplifier compatibility, shaft configuration and system requirements should be verified before installation.
