The Mitsubishi HC‑RF103K is part of the HC‑RF/HC‑RFS ultra‑low‑inertia, middle‑capacity servo motor series, optimized for applications requiring very fast acceleration and deceleration with low load inertia, such as pick‑and‑place, light tooling axes, and high‑speed positioning stages. Rated at 1 kW and 3000 rpm on a 200 V AC supply, it fits into a compact 100 × 100 mm frame with approximately 147 mm depth and around 3.9–4.5 kg mass, making it easy to integrate into tight machine layouts while still delivering adequate torque for small and medium axes.
HC‑RF103K uses a straight shaft with key output (keyed shaft), allowing secure torque transmission to couplings, pulleys or gears; it shares mechanical dimensions with the HC‑RFS103 family, and IP65‑class protection on the motor body helps it withstand typical industrial environments (shaft through portion excluded). The motor is built to Class F insulation standards and is intended for use with Mitsubishi MELSERVO J2‑Super and related 200 V servo amplifiers, forming a high‑response servo system suitable for precise position, speed and torque control. Encoder configuration follows the HC‑RF(S)103 family, which typically uses a 17‑bit (131072 ppr) encoder in the HC‑RFS103 variant; HC‑RF103K is the keyed‑shaft version within this 1 kW/3000 rpm family.
