Panasonic MHMF022L1U2M | 200W MINAS A6 High Inertia Servo Motor
Product Overview
The Panasonic MHMF022L1U2M is a high-precision AC servo motor from the industry-leading MINAS A6 Series. Engineered for applications that demand superior motion stability, this 200W (0.2kW) motor is a High Inertia model. It is specifically designed to provide the mechanical matching necessary to handle loads with fluctuating mass, effectively eliminating the vibration and "hunting" common in low-inertia systems.
With its 23-bit high-resolution encoder, integrated oil seal, and rugged IP67-rated construction, the MHMF022L1U2M is the premier choice for high-speed packaging, electronic assembly, and medical automation.

Key Features & Industrial Benefits
- Superior Stability for Resonant Loads: The MHMF "High Inertia" design is optimized for machines where the load-to-motor inertia ratio is high. This ensures shorter settling times and remarkably smooth motion control during rapid start-stop cycles, even in systems with mechanical non-rigidity.
- Ultra-High 23-bit Encoder Resolution: Equipped with a state-of-the-art 23-bit optical encoder, this motor provides over 8 million pulses per revolution. This allows for sub-micron positioning accuracy and minimizes torque ripple, leading to quieter operation and ultra-smooth rotation at low speeds.
- Industrial Durability (IP67 + Oil Seal): Engineered for the factory floor, the IP67 rating ensures the motor is completely dust-tight and can withstand powerful water jets. The factory-installed oil seal provides critical protection against industrial lubricants and coolants, significantly extending the service life in CNC environments.
- Compact "A6" Power Density: Panasonic has redesigned the internal structure to make the A6 series up to 30% smaller and lighter than the previous A5 generation. The MHMF022L1U2M offers a high power-to-size ratio, perfect for space-constrained robotic arms and compact control cabinets.
Common Industrial Applications
- Electronic Assembly: High-speed SMT pick-and-place and PCB handling
- Packaging Machinery: Precise labeling, capping, and film tension control
- Medical Automation: High-accuracy laboratory liquid handling and sample sorting
- Semiconductor Tools: Stable wafer handling in cleanroom environments
- Printing Equipment: High-resolution paper feed and carriage movement
