About MDMF752L1H6M Panasonic A6 7500W Motor + BRK , Torque Nm - 48, RPM - 1500

The Panasonic MINAS A6 MDMF752L1H6M is the version of the 7.5 kW middle inertia motor that includes a built-in holding brake. Because of this additional component, it is heavier and longer than the non-brake version. [1, 2]

Physical Specifications (Imperial Units)

Weight: Approximately 70.3 lbs (31.9 kg).
Width & Height (Flange): 6.93 inches (176 mm). This is a square flange motor.
Total Length:
- Body Length (with Brake): ~10.31 inches (262 mm).
- Total Length (Body + Shaft): ~14.76 inches (375 mm).
Shaft Dimensions:
- Diameter: 1.65 inches (42 mm).
- Length: 4.45 inches (113 mm). [1, 2, 3, 4]

Core Technical Specs

Rated Output: 7500 W (7.5 kW).
Rated Torque: 47.8 Nm (approx. 48 Nm).
Rated Speed: 1500 r/min (Max: 3000 r/min).
Holding Brake: Included (Electro-magnetic type).
Protection: IP67 rated for dust and water resistance. [1, 2, 3]

Key Differences from MDMF752L1G6M

The "H" in the model number (MDMF752L1H6M) indicates the holding brake, which adds roughly 9 lbs (4.1 kg) to the total mass and extends the body length compared to the "G" model you previously asked about.

The Panasonic MDMF752L1H6M performs the same high-precision motion tasks as the previous model, but with one critical added function: a Mechanical Holding Brake.

1. The Brake Function (The "H" in the Model)

The primary functional difference is the built-in electromagnetic brake.

Safety & Holding: Its main job is to hold the motor shaft in place when the power is turned off. This prevents heavy loads from falling due to gravity (common in vertical Z-axis applications) or moving due to external force.
Not for Stopping: It is a holding brake, not a braking brake. It should only be engaged once the motor has already come to a stop via electronic control; using it to stop a spinning motor will cause rapid wear.

2. High-Inertia Load Management

Because this is a 7.5 kW Middle Inertia motor, its function is to provide "muscle" for heavy machinery without losing control.

Balance: It provides enough internal inertia to handle large external loads (like a heavy CNC gantry) without the system becoming unstable or "shaking."
48 Nm Torque: This high torque allows for rapid acceleration and deceleration of heavy parts, significantly shortening machine cycle times.

3. Precision & Intelligence (MINAS A6 Features)

23-bit Absolute Positioning: It functions as its own "GPS." It remembers its exact position even after a power outage, so you don't have to "home" the machine every morning.
Vibration Suppression: It automatically detects "chatter" or resonance in the machine frame and uses software filters to cancel it out, ensuring smooth cuts or movements.
Predictive Maintenance: The motor monitors its own internal components (like the encoder and brake temperature) and can signal the controller if it detects it might fail in the future.

Summary of Use Case

If your machine has a vertical axis or a heavy tilted load that might slide when the power is cut, this "H" model is the required choice for safety.
