MITSUBISHI HC-SFS1024B AC Servomotor 2000rpm 1kW

Buy online your MITSUBISHI HC-SFS1024B AC Servomotor 2000rpm 1kW reference HC-SFS1024B from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This MITSUBISHI axis unit from the HC-SFS series is a closed-loop AC servo motor for the MELSERVO platform, used to drive CNC feed axes with precise position and speed control. It is a practical replacement motor for machine-tool service tasks, commonly sourced as a spare part for maintenance teams managing downtime and retrofit work.

Rated at 1.0 kW with a nominal speed of 2000 rpm, this model integrates an encoder for feedback and an integrated holding Brake for safe axis retention when power is removed. It is frequently used on X, Y or Z axes where reliable positioning and repeatability are required during CNC operations.

The mechanical interface includes a 24 mm smooth shaft and a 110 mm pilot that aligns with common machine-tool mounting faces. The motor is unventilated, which suits enclosed cabinets and harsh shop-floor environments where forced ventilation is not desired. A front-mounted power connector simplifies cable routing in tight spaces.

Electrical characteristics are designed for the MITSUBISHI servo ecosystem, with a nominal supply of 243 V three-phase AC and a current rating of 2.8 A. Encoder feedback supports precise axis control within MELSERVO drive configurations. Always verify the nameplate and drive parameters during field replacement to ensure a true drop-in match.

This reference is also encountered under common print variants such as HCSFS1024B, HC SFS1024B or HC-SFS1O24B, and is manufactured in Japan.
