Panasonic MSMA042A1F AC Servo Motor 400W High Inertia with 20-bit Encoder MINAS A5 Series

The Panasonic MSMA042A1F is a precision-engineered AC brushless servo motor from the industry-standard MINAS A5 series. This 400W motor is a High Inertia model, specifically designed to provide superior stability and control for applications with larger load-to-rotor inertia ratios. Whether you are maintaining a legacy system or building a new high-torque machine, the MSMA042A1F offers the reliability and performance required for modern industrial automation.

• High Inertia Stability: Optimized to handle heavy mechanical loads and fluctuating inertia, ensuring smooth motion without oscillation.
• High-Resolution Feedback: Equipped with a 20-bit incremental/absolute encoder (1,048,576 pulses/rev) for ultra-precise positioning and reduced vibration.
• Rapid Response: Features a 2.0 kHz frequency response, significantly shortening machine cycle times and improving throughput.
• IP65 Rated Protection: Built to withstand harsh factory conditions, with a dust-tight and water-resistant enclosure (excluding the shaft).
• Low Cogging Torque: Advanced magnetic design ensures smooth rotation even at very low speeds, critical for high-precision finishing tasks.

Ensuring an exact match is critical for servo replacements. Here is the technical breakdown of the MSMA042A1F code:
