The Panasonic MGMF242L1H6M functions as an Extra-Heavy Duty Safety Actuator. It is designed to combine massive 2.4 kW power with a mechanical "fail-safe" system, making it the standard choice for moving large, heavy machine components vertically.
1. High-Force Mechanical Holding (The Brake)
The primary function of the "H" model is to provide a physical lock when the machine is powered down.
- Static Friction Lock: It provides a holding torque of 16.1 Nm or higher. Since the motor's rated torque is 15.3 Nm, this brake is strong enough to hold the motors maximum continuous load indefinitely without electricity.
- Gravity Defense: On vertical (Z-axis) applications, it functions to prevent a heavy cutting head or robotic arm from crashing down during an emergency stop or power failure.
- Holding, Not Braking: It is designed to hold the position at 0 RPM, not to slow the motor down while it is spinning.
2. High-Torque Prime Motion (2.4 kW)
- 15.3 Nm Continuous Torque: It functions to move massive mechanical assemblies, such as heavy gantries or large ball screws, at full speed (3000 RPM) without losing position.
- 45.9 Nm Peak Burst: It can provide a 3x "punch" of torque to overcome "stiction" (static friction) when starting a heavy machine from a dead stop.
3. Load Stabilization (Middle Inertia)
Because this is a Middle Inertia motor in a large 176mm frame, its physical build serves a specific stabilization function:
- Mechanical Buffer: The internal rotor has significant mass, which acts as a "damper." This functions to prevent the machine from "shaking" or vibrating when attached to high-friction or heavy loads.
- Consistent Control: It is ideal for machines where the load weight might vary, as the motor's own inertia helps maintain smooth, predictable motion.
4. Surgical Precision on a Large Scale
- 23-bit Feedback: Despite its 37 lb weight, it functions with microscopic accuracy, monitoring 8,388,608 unique points per revolution.
- Absolute Tracking: It functions as a permanent digital ruler. It remembers its exact mechanical position even after power is cut, so you never have to "home" the machine at the start of a shift.
5. Rugged Environmental Protection
- IP67 Sealing: It is designed to function in "wet" areas. It is fully protected against dust and can be sprayed with high-pressure cutting oils or coolants without internal damage.
Typical Use Case:
This is the ideal motor for the vertical (Z-axis) of large-scale CNC machines, heavy-duty injection moulding auxiliary axes, and large robotic joints that requi
