About MDMF302L1H6M Panasonic A6 3000W Motor + BRK , Torque Nm - 14.3, RPM - 2000

The Panasonic MDMF302L1H6M is the 3.0 kW Middle-Inertia AC servo motor equipped with an integrated holding brake. It is designed for heavy-duty applications where high torque and vertical safety are paramount. [1]

Function

Fail-Safe Vertical Security: The integrated electromagnetic brake's primary function is to lock the shaft when power is removed. This prevents heavy vertical loads (like a large CNC spindle) from falling due to gravity during an emergency stop or power failure.
High-Torque Heavy Lifting: Delivers a massive 14.3 Nm of continuous torque, allowing it to drive heavy mechanical parts such as large ball screws and high-mass industrial robotics.
Load Stability (Middle-Inertia): The heavier internal rotor acts as a stabilizer. This provides a better "inertia match" for massive loads, preventing the vibrations and shaking that occur when using smaller-inertia motors on heavy machines.
Extreme Precision: Uses a 23-bit encoder (8.38 million pulses/rev) to ensure that even while moving heavy loads, the motor maintains micron-level positioning accuracy. [1]

Technical Specifications

Based on official Panasonic Industry data:

Feature [1, 2, 3]	Specification
Rated Output	3000 W (3.0 kW)
Rated Torque	14.3 Nm (Peak: 42.9 Nm)
Rated Speed	2000 RPM (Max: 3000 RPM)
Brake Torque	16.1 Nm or more (Static friction)
Brake Voltage	24 V DC ( 2.4V)
IP Rating	IP67 (Dust-tight and waterproof)

Physical Dimensions & Weight (Inches & Lbs)

Because this motor combines a 3kW stator, a middle-inertia rotor, and a brake assembly, it is one of the larger units in the A6 3kW class. [1, 2]

Weight: Approximately 26.90 lbs (12.2 kg).
Width & Height (Flange): 6.93 inches (176 mm square).
Length (Total Body): Approximately 8.33 inches (211.5 mm).
Shaft Diameter: 0.94 inches (24 mm). [1]

Compatible Drivers

This motor requires the 3.0 kW "F-Frame" drivers: [1]

Multifunction: MFDLTA3SF
Basic / Position: MFDLNA3SE
Network (EtherCAT): MFDLNA3NE

The primary function of the Panasonic MDMF302L1H6M is to provide high-torque power with a fail-safe safety lock for heavy-duty industrial machinery. It is the "heavy-lifter" of the 3.0 kW range.

1. Fail-Safe Position Holding (Primary Brake Function)

The "H" designation identifies the integrated electromagnetic brake.

Safety Lock: It automatically locks the motor shaft using internal springs whenever power is lost or an Emergency Stop is triggered.
Vertical Protection: Its most critical job is to prevent heavy machine parts (like a large milling head or vertical lift) from crashing down due to gravity.
Strong Holding Force: It provides 16.1 Nm of holding torquehigher than the motor's running torqueensuring the load stays "frozen" without needing active motor power.

2. High-Torque Force (Heavy Duty Output)

While high-speed motors spin faster, this motor focuses on pushing power.

Raw Strength: It delivers a constant 14.3 Nm of torque (surging to 42.9 Nm peak). This allows it to move heavy loads that require massive force to start, such as large-diameter ball screws.
Applications: Ideal for large CNC machines, industrial presses, and heavy robotic arms.

3. "Middle-Inertia" for Stability

The rotor inside this motor is specifically weighted to act as a mechanical stabilizer.

Inertia Matching: Moving a heavy load with a lightweight motor causes vibration. The "Middle-Inertia" design provides a physical balance, allowing the motor to control high-mass loads with smooth, steady motion and zero shaking.
Easier Tuning: It makes the machine much easier to calibrate because the motor isn't "jumpy" when the weight of the load changes.

4. Precision at Scale

Despite its brute force, it maintains surgical accuracy:

23-bit Accuracy: It tracks its position within 8,388,608 steps per turn. This allows for micron-level precision even on machines moving hundreds of kilograms.
Real-Time Correction: It communicates with the driver 3,200 times per second to instantly correct any deviations in speed or path.

5. Rugged Protection (IP67)

It is functionally sealed against heavy dust, oil, and water splashes. This allows it to work reliably on factory floors where metal shavings and coolants are present.
