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.
