About MSMF402L1H6M Panasonic A6 4000W Motor + BRK , Torque Nm - 12.7, RPM - 3000

The Panasonic MSMF402L1H6M is a 4000W (4.0 kW) low-inertia AC servo motor from the MINAS A6 series, specifically equipped with an integrated holding brake. [1, 2]

Function

Precision Motion & Fast Response: Its primary function is to provide rapid, high-accuracy positioning for industrial automation. As a low-inertia model, it is optimized for applications with frequent starts, stops, and high acceleration, such as in packaging and robotic machinery.
Safety Holding: The built-in electromagnetic holding brake automatically locks the motor shaft when power is removed. This is critical for preventing heavy vertical loads from falling or axes from moving during an emergency stop or power failure.
High-Resolution Feedback: It utilizes a 23-bit absolute/incremental encoder (8,388,608 pulses/rev), allowing for extreme positioning precision and real-time monitoring. [1, 2, 3]

The primary function of the Panasonic MSMF402L1H6M 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, combining extreme agility with fail-safe security.

1. Fail-Safe Position Holding (Primary Brake Function)

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.
Vertical Load 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.
High Holding Force: It provides 16.2 Nm of static holding torquesignificantly higher than the motor's running torqueensuring the load stays "frozen" in place without needing active motor power.

2. High-Speed "Low-Inertia" Agility

The "MSMF" design is built for acceleration.

Rapid Cycling: With its lightweight internal rotor, this motor can reach its 3000 RPM rated speed 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 packaging, and electronic component placement.

3. Surgical Positioning Precision

Despite its brute 4.0 kW power, it functions with extreme accuracy:

23-bit Encoder: It tracks its position within 8,388,608 steps per single turn. This allows for micron-level accuracy when positioning heavy parts.
Rapid Settling: It works with the driver to stop instantly at a coordinate without "bouncing" or vibrating, which is vital for high-speed production quality.

4. Continuous High-Frequency Output

Sustained Force: It delivers a constant 12.7 Nm of torque, providing the necessary "muscle" to overcome mechanical friction in heavy-duty machinery.
Environmental Protection: Its IP67 rating means it is functionally sealed against dust and liquid splashes, making it a reliable component for harsh factory floors (e.g., food processing or metal machine shops).

5. Real-Time Feedback Hub

It communicates its position, speed, and torque data back to the driver 3,200 times per second. This allows the system to instantly adapt to changes in the mechanical load, ensuring perfectly smooth motion.
