Function & Features
- Integrated Safety Brake: The built-in electromagnetic brake provides 24.5 Nm or higher of static friction torque. Its primary function is to hold the load in place during a power loss or emergency stop, which is critical for vertical (Z-axis) safety.
- Middle Inertia Stabilization: The rotor design (63.3 x 10 kgm) acts as a mechanical damper, providing high stability and reducing vibration for heavy or fluctuating loads.
- 23-bit Absolute Encoder: Offers surgical precision with 8,388,608 pulses per revolution and remembers its position without a battery.
- Environmental Protection: IP67 rated, making it completely dust-tight and resistant to high-pressure water/oil spray.
The Panasonic MGMF292L1H6M functions as an Ultra-High Power Safety Actuator. It is the "top-of-the-line" model for the 176 mm frame size, providing the maximum torque (18.5 Nm) available before moving to the massive 220 mm motors.
1. High-Load Mechanical Locking (The Brake)
The primary function of the "H" model is to act as a fail-safe.
- Static Safety Lock: It provides a holding torque of 24.5 Nm. Because this is significantly higher than the motor's rated torque (18.5 Nm), it can easily hold the weight of a heavy machine gantry or a large robotic arm indefinitely without power.
- Emergency Brake: On vertical (Z-axis) axes, it functions to instantly lock the shaft the moment power is cut, preventing a "free-fall" that could destroy expensive tooling or cause injury.
2. Maximum Torque in a Compact Frame
- 18.5 Nm Continuous Torque: It functions to move heavy mechanical assemblies at high speeds (up to 3000 RPM). It is designed for applications where you need the strength of a large motor but have limited space in the machine frame.
- 55.5 Nm Peak "Punch": It can provide a 3x torque burst for rapid accelerations, allowing a heavy machine to reach full speed almost instantly.
3. Precision Tracking & Position Memory
- 23-bit "Microscopic" Feedback: Despite its 45.4 lb weight, it functions with incredible precision, monitoring 8,388,608 unique points per revolution. This allows a 2.9 kW machine to perform cuts or placements with micron-level accuracy.
- Absolute Tracking: It functions as a digital memory. It remembers exactly where the machine was when it was turned off, so you never have to "home" the machine at the start of a shift.
4. Stability for Shifting Loads (Middle Inertia)
- Vibration Cancellation: Because it is a Middle Inertia type, the rotor has enough mass to act as a mechanical stabilizer. It functions to prevent the machine from "shaking" or becoming unstable when moving loads with high friction or varying weight.
5. Rugged Industrial Build
- IP67 Sealing: It is designed to function in the "danger zones" of a factory. It is fully protected against metallic dust and can be sprayed with high-pressure oils or coolants without failing.
- 35mm Shaft: The shaft is extra thick to handle the 55.5 Nm peak torque without twisting or snapping under heavy stress.
