Mitsubishi HF-KP23K-S11 Low-Inertia Servo Motor for MELSERVO HF Series

The Mitsubishi HF-KP23K-S11 (HF-KP23K-S11) is an ultra-compact low-inertia AC synchronous servo motor developed for high-precision motion control within the Mitsubishi MELSERVO HF series family. Engineered for dynamic positioning tasks, this servo motor features an ultra-compact mechanical design with a low moment of inertia, enabling fast acceleration, sharp deceleration, and responsive cycling across demanding industrial machinery applications. The motor incorporates an integrated high-resolution encoder to deliver dependable feedback for closed-loop position and speed regulation. Built with a keyway shaft configuration, the HF-KP23K-S11 provides positive torque transmission and secure mechanical coupling to gearboxes, drive pulleys, and machine axes. Designed to operate seamlessly alongside compatible Mitsubishi MELSERVO servo amplifiers, the unit supports industrial automation equipment such as assembly stations, packaging machinery, electronic manufacturing systems, material handling mechanisms, and automated feed systems. Its low-inertia construction minimizes mechanical stress during rapid reversal cycles, making it suitable for both routine maintenance replacements and new automation builds requiring reliable, repeatable dynamic control.
