HF-KN13 Mitsubishi Electric MR-JE Series Low Inertia AC Servo Motor

The Mitsubishi Electric HF-KN13 is a high-precision, low-inertia AC servo motor belonging to the advanced MR-JE Series. Designed as a cost-effective yet high-performance successor to the popular MR-E series, the HF-KN13 delivers exceptional responsiveness and positioning accuracy in a compact form factor. With a rated output of 100W, this motor is engineered for applications requiring rapid start-stop cycles, high-speed operation, and precise torque control.

The "KN" designation identifies this as a low-inertia, small-capacity motor (3000 r/min rated speed), making it ideal for driving lightweight loads with maximum efficiency. It features a high-resolution 17-bit encoder (131,072 pulses/rev) and an IP65 protection rating (for the motor body and encoder), ensuring reliable operation in harsh industrial environments. Whether used in packaging, electronics assembly, or general automation, the HF-KN13 offers a perfect balance of power, precision, and ease of use.

Key Features & Benefits

• High-Precision Control: Equipped with a standard 17-bit incremental encoder (131,072 pulses/revolution), enabling ultra-fine resolution for precise positioning and smooth low-speed operation.
• Ultra-High Response: Achieves a speed frequency response of 2.0 kHz, significantly reducing settling time and improving cycle efficiency in high-speed picking and placing applications.
• Compact & Lightweight: Weighing approximately 0.6 kg (for the J-model), the low-inertia design allows for rapid acceleration and deceleration, minimizing mechanical stress on the driven equipment.
• Rugged Construction: Features an IP65 protection rating (motor and encoder), making it resistant to dust, water jets, and oil, suitable for harsh factory floors without additional enclosures.
• Advanced Tuning Capabilities: Supports "One-Touch Tuning" for automatic gain adjustment and includes Adaptive Vibration Suppression and Robust Filter II to eliminate resonance and stabilize operation.
• Energy Efficient: Incorporates a "Tough Drive" feature with large-capacity capacitors to utilize regenerative energy, reducing power consumption and heat generation.
• Flexible Wiring: Supports both Sink (NPN) and Source (PNP) wiring configurations for input signals, simplifying integration with various PLCs and controllers.

• Built-in Positioning: Eliminates the need for an external motion controller in simple point-to-point applications.
• Communication: Supports Modbus RTU and can be integrated into CC-Link, MECHATROLINK, or EtherCAT networks via optional adapter cards.

Typical Applications

• Packaging Machinery: Labeling machines, filling nozzles, and sealing bars requiring high-speed synchronization.
• Electronics Manufacturing: Pick-and-place machines, wire bonders, and PCB handling equipment.
• Small Conveyors & Feeders: Precise indexing and length measurement in material handling systems.
• Medical & Lab Automation: Precise fluid handling and sample positioning.
• Textile Machinery: Yarn guides and tension control in knitting or weaving machines.
