The Panasonic MGMF442L1G6M functions as an Extra-High Torque Prime Mover. At 4.4 kW, it is designed to provide massive "muscular" force for heavy-duty industrial axes that require high-speed movement without losing accuracy.
1. Massive Mechanical Drive (Power Function)
The primary function is the delivery of 28.0 Nm of continuous torque.
- High Force Output: It maintains this 28 Nm force at its rated speed (1500 RPM), allowing it to drive massive ball screws or heavy industrial belt systems.
- 84 Nm Peak "Punch": It can provide a momentary burst of 84 Nm (3x its rating). This is critical for overcoming "stiction" (static friction) when starting a multi-ton machine from a dead stop or for rapid, aggressive accelerations.
2. Stability for Massive Loads (Middle Inertia)
This motor is a Middle Inertia type, which serves a specific damping function:
- Mechanical Stabilizer: The internal rotor has significant mass, which acts as a "gyroscope." This functions to prevent the machine from "shaking" or vibrating when it is attached to a load that is much heavier than the motor itself.
- Resonance Suppression: It is ideal for machines where the load weight varies, as the motor's own inertia keeps the control loop stable and predictable.
3. Surgical Precision at Scale
Despite its 46 lb weight, its function is high-resolution tracking:
- 23-bit Position Feedback: It monitors its position at 8,388,608 unique points per revolution. This allows a 4.4 kW machine to position tools with a precision thinner than a human hair.
- Absolute Memory: It functions to "remember" its location. You never need to "home" the machine because the motor tracks its mechanical position even when the power is off.
4. Heavy-Duty Mechanical Interface
- 35mm Reinforced Shaft: The shaft is extra thick to function as a bridge for the 84 Nm peak torque without twisting or snapping under extreme stress.
- IP67 Sealing: It is designed to function in "wet" areas. It is fully protected against dust and can be sprayed with high-pressure oils or coolants inside a CNC machining center.
Typical Applications
- Large CNC Boring & Milling: Driving the primary X or Y axis of machines used for mining or aerospace parts.
- Industrial Presses: Providing precise depth control for heavy metal forming.
- Material Handling: Moving heavy automotive chassis or steel pallets at high speed.
