About MSMF102L1H6M Panasonic A6 1000W Motor + BRK, Torque Nm - 3.18, RPM - 3000
The Panasonic MSMF102L1H6M is a 1000W (1.0kW) low-inertia AC servo motor from the MINAS A6 series, featuring an integrated electromagnetic
holding brake. [

Function
Its primary function is to provide precise motion control for high-speed industrial automation. The integrated
holding brake acts as a safety mechanism, locking the motor shaft in place when power is removed to prevent accidental movement or "dropping" in vertical load applications. [

Physical Specifications
The inclusion of a brake adds both weight and length compared to the non-brake version (G6M). Based on technical data from
Panasonic Industry and retailers like
Industrybuying, the specifications are:
- Weight: Approximately 10.36 lbs (4.7 kg).
- Dimensions (Converted to Inches):
- Length: ~7.81 inches (198.5 mm) Total length including the brake, measured from the flange face to the rear.
- Width (Flange): 3.94 inches (100 mm square).
- Height (Flange): 3.94 inches (100 mm square).
- Shaft Diameter: ~0.75 inches (19 mm). [1, 2, 3]
Key Performance Specs
- Rated Torque: 3.18 Nm.
- Rated Speed: 3000 RPM.
- Protection Class: IP67, making it dust-tight and resistant to water immersion.
- Encoder: 23-bit (8,388,608 pulses/rev) absolute/incremental system for high-resolution positioning. [1, 2, 3, 4, 5]
Primary Functions
- Precision Motion Control: It converts electrical signals into highly accurate rotary motion. Its 23-bit encoder allows for "micro-degree" positioning accuracy (8.38 million pulses per revolution), making it ideal for tasks like semiconductor manufacturing or robotic assembly.
- Dynamic Response: Designed as a "Low Inertia" motor, it is optimized for applications requiring rapid acceleration and frequent starts/stops, such as packaging machinery.
- Safe Position Holding (Integrated Brake): Unlike the G6M model, this motor features a built-in electromagnetic holding brake.
- Fail-Safe Design: The brake is a "power-off" type, meaning it is automatically engaged by internal springs whenever power is lost or cut.
- Vertical Load Safety: It is specifically used to prevent a machine axis (like a robot arm or a CNC Z-axis) from falling or moving due to gravity when the system is powered down. [1, 2, 3, 4, 5, 6, 7]
Operational Requirements & Limits
- Not for Dynamic Braking: The internal brake is strictly a holding brake. It is designed to hold the shaft stationary, not to slow down or stop a motor while it is spinning. Using it to stop a moving load will cause rapid wear and eventual failure.
- Energise to Release: To allow the motor to rotate, you must apply 24V DC to the brake coil to overcome the spring force and release the friction disc.
- Holding Torque: The brake provides a static friction torque of 8.0 Nm or more, which is significantly higher than the motor's rated torque (3.18 Nm) to ensure a secure lock. [1, 2]
