Mitsubishi’s HC-SFS152G2120 servo motor is engineered for precision applications. It operates at a nominal current of 9 A, capable of a maximum peak current of 27 A. The motor's continuous torque rating is 7.16 N·m, which can spike to 21.6 N·m during peak operational bursts. This unit provides 25.6 kW/s of power when maintaining continuous rated torque.

With speeds ranging from 2000 r/min as nominal to a maximum of 3000 r/min, it allows for versatile motion control. Instantaneous permissible speeds can reach up to 3450 r/min. An encoder provides feedback with a resolution of 131072 pulses per revolution, ensuring accurate performance tracking.

The standard straight shaft enables straightforward integration into systems requiring motion control. While an electromagnetic brake is not included, the fully enclosed design enhances its durability, allowing it to operate in dust or high moisture environments, as indicated by the IP65 protection rating.

Built with a moment of inertia of 20.0 × 10⁻⁴ kg·m², the motor is best suited for applications with a load to inertia ratio of 15 times or less. This component weighs 9.0 kg, making it manageable for various mounting contexts. With an insulation rating of Class F, the motor is developed to withstand a range of operating temperature conditions for reliable functionality.
