Core Features & Benefits
Middle Inertia Design
The MDMA152A1G features a middle inertia rotor (11.2 × 10⁻⁴ kg*m² without brake), specifically optimized for applications requiring balanced performance between rapid acceleration and stable load handling. This design provides:
Enhanced stability for general industrial automation
Reduced settling time in point-to-point positioning
Smooth operation with moderate load inertia ratios
300% Overload Capacity
With a peak torque of 21.5 N*m (300% of rated torque), this motor handles demanding acceleration requirements and sudden load fluctuations without stalling.
Robust Mechanical Construction
Oil Seal: The shaft includes an oil seal to prevent lubricant ingress - ideal for gearbox or pulley-coupled applications
IP65 Rating: Standard protection against dust and water jets enables use in harsh workshop environments when used with oil-resistant cylindrical connectors
High-Resolution Feedback
Equipped with a 2500 P/R incremental encoder, providing precise position and speed feedback for high-resolution control loops. The motor also supports 17-bit incremental and 17-bit absolute encoder upgrades.
Wide Speed Range
Capable of operation from standstill up to 3000 RPM maximum speed, making it suitable for both high-speed machining and low-speed positioning applications.
IP65 Environmental Protection
Rated IP65 (excluding shaft penetration and connector pin parts), the motor is protected against dust ingress and low-pressure water jets, ensuring reliable operation in demanding industrial environments.
Applications
The Panasonic MDMA152A1G was originally engineered for demanding industrial automation applications requiring middle inertia performance:
General Automation Machinery: Assembly lines, pick-and-place systems, and indexing drives
Material Handling: Conveyor systems, palletizers, and automated storage/retrieval systems
Packaging Machinery: Wrapping, filling, and labeling equipment requiring precise torque control
Textile Machinery: Spinning, winding, and yarn tension control systems
Machine Tools: Feed axis drives for milling, turning, and grinding equipment
Industrial Equipment: Injection molding machines and press feeders
Research & Development: Academic research on PMSM control systems

Why Choose This Motor (For Legacy Systems)
OEM Replacement
For existing machinery with failed MDMA152A1G units, direct replacement minimizes downtime and avoids control system re-engineering.
Proven Reliability
Panasonic MINAS A series has been widely adopted across industrial sectors worldwide, with decades of proven field performance.
Cost-Effective Maintenance
Replacing with an identical model eliminates:
Mechanical rework (mounting dimensions match exactly)
Drive reprogramming and re-tuning
Cabling modifications
Available Substitute
The MDMA152A1C is listed as a direct substitute, providing an alternative sourcing option.
