Technical specifications for
HG-KN43
The Mitsubishi HG-KN43 servo motor
The Mitsubishi HG-KN43 servo motor from the MELSERVO-JE series is a high-performance, compact, low-inertia AC servo motor built for precision-driven applications. Ideal for robotics, packaging machinery, and semiconductor equipment, it delivers exceptional accuracy and responsiveness, making it a reliable choice for systems requiring tight control.With a rated output power of 0.4 kW (400 W) and rated torque of 1.3 Nm, it is designed to deliver up to 3.8 Nm of maximum torque, ensuring sufficient headroom for dynamic loads. Operating at a rated speed of 3000 rpm and capable of reaching 5000 rpm at maximum, it supports rapid acceleration and deceleration.
The motor features low inertia (0.375 kg·cm²), which enhances responsiveness in high-speed motion applications. It comes with a keyway shaft type, no brake, and a high-resolution 17-bit encoder (131,072 pulses/rev) for precise feedback control. The motor’s IP65 protection rating ensures durability against dust and water, suitable for demanding industrial environments.
The natural cooling method contributes to a compact and maintenance-free design, while its dimensions (60 mm × 60 mm × 128.3 mm) and light weight (approximately 1.4 kg) make it easy to integrate into space-constrained systems. Additionally, it meets international standards with CE, UL/cUL, EAC, and UKCA certifications, ensuring global compliance and quality assurance.
