The Panasonic MSMF502L1H6M is a 5000W (5.0 kW)
Low-Inertia AC servo motor from the MINAS A6 series, featuring an integrated electromagnetic
holding brake. It is the highest-output "fast-response" motor in the 3000 RPM range. [

The primary function of the Panasonic MSMF502L1H6M is to provide high-speed, high-power motion control with an integrated safety lock for heavy-duty industrial automation. It is the most powerful "low-inertia" motor in the 3000 RPM class, balancing extreme agility with fail-safe security.
1. Fail-Safe Vertical Security (Holding Brake)
The "H" designation identifies the built-in electromagnetic holding brake.
- Safety Lock: It automatically locks the motor shaft using internal springs whenever power is lost or an Emergency Stop is triggered.
- Gravity Protection: Its most critical job is to prevent heavy machine components (like a large robotic head or a vertical Z-axis) from crashing down due to gravity.
- Strong Holding Force: It provides 24.5 Nm of static holding torquesignificantly higher than the motor's running torque (15.9 Nm)ensuring the load stays "frozen" without needing active motor power.
2. High-Speed "Low-Inertia" Agility
The "MSMF" design is specifically engineered for acceleration.
- Rapid Cycling: Despite its massive 5.0 kW power, it has a lightweight internal rotor. This allows it to reach 3000 RPM almost instantly.
- Applications: It is the standard choice for high-output machines performing hundreds of operations per minute, such as high-speed bottling, large-scale plastic injection molding, and fast-cycle material handling.
3. Surgical Positioning Precision
Even when outputting massive force, it maintains micro-precision:
- 23-bit Encoder: It tracks its position within 8,388,608 steps per turn. This allows for micron-level accuracy when positioning heavy parts.
- Quick Settling: It works with the driver to stop instantly at a coordinate without "bouncing" or vibrating, which is vital for maintaining production quality at high speeds.
4. Continuous Heavy-Duty Output
- Sustained Force: It delivers a constant 15.9 Nm of torque, providing the necessary "muscle" to overcome mechanical friction and air resistance in large-scale automated systems.
- Environmental Protection: Its IP67 rating means it is functionally sealed against dust and liquid splashes, making it reliable for harsh factory floors (e.g., food processing or metal machine shops).
5. Real-Time Feedback Hub
- It communicates its status to the driver 3,200 times per second (3.2 kHz). This allows the system to make instantaneous power adjustments if the load changes, ensuring perfectly smooth motion even under stress.
