About MDMF402L1G6M Panasonic A6 4000W Motor , Torque Nm - 19.1, RPM - 2000

The Panasonic MDMF402L1G6M is a 4.0 kW middle-inertia AC servo motor from the MINAS A6 series, designed for applications requiring high precision and steady torque. Unlike low-inertia models, it provides a stable "middle inertia" rotor to better handle high-mass loads without vibration. [1, 2, 3, 4]

Physical Specifications (Inches & Lbs)

Based on official data from Panasonic Industry, the converted dimensions for this motor are:

Feature [1, 2, 3, 4, 5]	Specification
Weight	~29.54 lbs (13.4 kg)
Width & Height (Flange)	6.93 inches (176 mm)
Length (Motor Body)	~6.81 inches (173 mm) [Estimated based on A6 series 4kW middle inertia frame]
Shaft Diameter	1.38 inches (35 mm)
Shaft Length	2.76 inches (70 mm)

Function

High Torque Stability: Delivers a continuous rated torque of 19.1 Nm. Its middle-inertia rotor acts as a stabilizer for high-mass mechanical loads, making it ideal for CNC machinery and industrial robots.
Precision Positioning: Features a 23-bit absolute/incremental encoder, providing over 8.38 million pulses per revolution for ultra-fine accuracy.
Harsh Environment Use: Rated IP67, which ensures the motor is dust-tight and can withstand water immersion, essential for durability on factory floors.
High Performance: Capable of a peak torque of 57.3 Nm to overcome high starting friction. [1, 2, 3, 4, 5]

Key Technical Specs

Rated Output: 4000 W (4.0 kW).
Rated / Max Speed: 2000 RPM / 3000 RPM.
Voltage: 200 V AC.
Holding Brake: Not included (denoted by the "G" in the model number).

The primary function of the Panasonic MDMF402L1G6M is to provide high-torque, stable motion control for heavy-duty industrial machinery. It is the "power lifter" of the 4.0 kW range, specifically designed to move massive loads that require steady force rather than just high speed.

1. High-Torque Heavy Lifting

With a rated torque of 19.1 Nm (and a massive peak of 57.3 Nm), its main role is to provide the raw strength needed to move heavy mechanical parts. It is commonly used in:

Large CNC Milling & Boring: Moving heavy cutting heads or large metal workpieces.
Industrial Forming: Providing consistent force for metal bending, stamping, or pressing.
Heavy Material Handling: Driving large-scale conveyors or heavy-duty gantry systems.

2. "Middle-Inertia" Load Balancing

This is its most critical functional advantage over the "Low Inertia" models.

The Stabilizer: When moving a heavy load (like a 200kg steel table), a lightweight motor often vibrates or "shakes" because it lacks the physical mass to control the load's momentum.
Smooth Motion: This motor features a heavier internal rotor that acts as a mechanical stabilizer, providing a better "inertia match." This results in much smoother movement and significantly easier tuning for high-mass mechanical parts.

3. Precision at Scale

Despite its strength, it maintains surgical accuracy:

23-bit Resolution: It divides a single rotation into 8,388,608 steps. Even when pushing a load weighing hundreds of kilograms, it can position that load within microns of the target.
High Response: It communicates with its driver 3,200 times per second (3.2 kHz) to instantly correct any deviations in speed or position caused by changing resistance.

4. Rugged Industrial Durability

IP67 Rating: It is functionally sealed against heavy dust, oil mist, and water spray. This allows it to live in "dirty" environments like machine shops where coolants and metal shavings are constantly present.
Thermal Efficiency: Designed to run at its rated 2000 RPM continuously under full load without overheating, ensuring 24/7 reliability on production lines.

5. Smart Health Feedback

The motor acts as a diagnostic sensor, 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.
