Mitsubishi HF-KP43J Servo Motor

The Mitsubishi HF-KP43J AC Servo Motor from the HF-KP Series delivers 400 W of rated output power in a compact 200 VAC class package, making it well-suited for precision motion control in automated systems. Featuring a high-resolution incremental encoder for accurate position feedback, it achieves up to approximately 3000 RPM with a straight, keyed shaft and flange-mount design for straightforward installation. The unit is self-cooled and rated IP65 protection (excluding the shaft area), helping it stand up to demanding industrial environments in CNC machines, packaging equipment, robotics, and assembly lines. Typical applications include pick-and-place systems, conveyors, labeling machines, semiconductor equipment, and other precision manufacturing processes where smooth, reliable motion control is essential. Common replacements include Mitsubishi HF-KP23J, HF-MP43, and HC-KFS43.
