About MHMF402L1G6M Panasonic A6 4000W Motor , Torque Nm - 19.1, RPM - 2000
The Panasonic MHMF402L1G6M is a 4000W (4.0 kW) High-Inertia AC servo motor from the MINAS A6 series. It is the most stable 4kW motor in the lineup, specifically designed to handle very large mechanical loads without vibration.
Function
- Maximum Load Stability: Its primary function is to provide steady, vibration-free motion for machines with high-mass components. The High-Inertia rotor acts as a mechanical stabilizer, making it the best choice for large gantries or heavy robotic arms.
- Precision Control: Equipped with a 23-bit absolute/incremental encoder (8.38 million pulses/rev) for micron-level positioning accuracy.
- High-Torque Performance: Delivers a robust 19.1 Nm of continuous torque, capable of surging to 57.3 Nm to overcome high starting friction.

The primary function of the Panasonic MHMF402L1G6M is to provide maximum mechanical stability and power for very large, high-mass industrial loads. It is the "heavyweight stabilizer" of the 4.0 kW A6 range, built to move massive parts without the vibration that smaller motors would suffer from.
1. Maximum Stability (High-Inertia Advantage)
The "High-Inertia" design is its most critical functional feature.
- The "Flywheel" Effect: When moving a massive machine part (like a large steel gantry), a lighter motor may cause the system to shake or "hunt" for its position. This motor has a heavy internal rotor that acts as a mechanical stabilizer, absorbing mechanical shocks and preventing resonance.
- Load Matching: It is designed specifically for machines with a high "load-to-motor" inertia ratio, ensuring smooth control even when the weight being moved is significantly larger than the motor itself.
2. High-Torque Sustained Power
While high-speed motors (MSMF) focus on agility, this motor is built for sustained force.
- Raw Push: It delivers a constant 19.1 Nm of torque (surging to 57.3 Nm peak). This provides the necessary "muscle" to drive large-diameter ball screws and heavy-duty gearboxes that move massive components.
- Applications: It is the standard choice for large-scale CNC gantries, heavy material handling robots, and industrial spinning/winding machinery.
3. Precision at Scale
Despite the brute force and heavy loads, it maintains surgical accuracy:
- 23-bit Resolution: It tracks its position within 8,388,608 increments per single turn. This allows a massive machine part to be positioned within microns of its target.
- High Response Frequency: It communicates with the driver 3,200 times per second (3.2 kHz) to instantly correct any deviations in speed or path caused by the heavy load.
4. Rugged Industrial Performance
- IP67 Environmental Shield: The motor is functionally sealed against heavy dust, oil mist, and high-pressure water/oil spray. This allows it to work reliably on the "front lines" of heavy manufacturing floors.
- Heat Dissipation: Its larger physical size (176mm flange) allows it to dissipate heat efficiently even when running at its rated 2000 RPM for 24/7 production cycles.
5. Smart Feedback
- It acts as a diagnostic hub, feeding real-time data back to the driver about its temperature and torque usage. This allows for predictive maintenance, warning the operator of mechanical wear before a breakdown occurs.
