Mitsubishi HG‑KN23BK Synchronous Servo Motor with Brake for MELSERVO-J4 Series

The Mitsubishi HG‑KN23BK (HG‑KN23BK) is an ultra-compact low-inertia synchronous AC servo motor designed for high-performance motion control within the MELSERVO-J4 series drive systems. Engineered for precision positioning and dynamic responsiveness, this rotary servo motor features an integrated electromagnetic holding brake and a built-in high-precision absolute encoder to ensure reliable position retention and exact feedback during automation tasks. The motor is suitable for integration into multi-axis robotic arms, electronic component assembly machines, packaging lines, and computerized numerical control machinery that require dependable and repeatable operation. By pairing seamlessly with compatible Mitsubishi MELSERVO-J4 servo amplifiers, the unit delivers stable velocity control and swift acceleration profiles under varying load conditions. Its low-inertia construction enables agile motion cycles, while the robust integrated brake secures the load safely when power is removed or in emergency stop situations. Built to withstand industrial factory floor environments, this servo motor helps maintain overall system efficiency, minimized downtime, and superior operational accuracy across critical production lines.
