About ECMA-E11310RS Delta Servo Motor 1000W M , Torque Nm - 4.77 , RPM - 2000
The ECMA-E11310RS is a medium-inertia actuator designed to move heavier mechanical loads with high stability. Its primary function is to convert electrical power from the drive into precise rotational motion, specifically optimized for applications where load resistance is higher.
Core Functional Roles
- High-Torque Performance: Unlike high-speed models, this motor provides a higher rated torque of 4.77 Nm. This makes it the "muscle" of the system, capable of starting and stopping heavy machinery parts without losing synchronization.
- Medium Inertia Stability: The "E" series design has a higher internal rotor inertia. This is functional for maintaining smooth motion and reducing vibration when the motor is coupled to heavy loads (like large lead screws or heavy conveyor belts).
- Precision Positioning: It uses its 20-bit incremental encoder to send 1,280,000 pulses per revolution back to the drive. This allows for microscopic accuracy in positioning, even under significant weight.
- Environmentally Sealed Operation: Its IP65 rating and built-in oil seal allow it to function inside oily, dusty, or damp industrial environments without internal damage.
Common Industry Tasks
- Material Handling: Driving heavy-duty conveyors and elevators.
- Machine Tool Feed: Powering the axes of large CNC milling or boring machines.
- Textile & Printing: Maintaining steady tension and precise feed in heavy fabric or paper processing.
- Industrial Robotics: Providing the high torque needed for the base or primary joints of heavy robotic arms.
The ECMA-E11310RS is a 1000W (1.0 kW) Medium Inertia AC Servo Motor from Delta's ASDA-A2 series. Compared to the "C" series you asked about earlier, this "E" series motor provides higher torque at a lower rated speed, making it better for moving heavier loads.

Function & Performance
- High Torque: Delivers a rated torque of 4.77 Nm (significantly higher than the 3.18 Nm of the 1kW "C" series) and a peak torque of 14.32 Nm.
- Medium Inertia: Designed for applications with larger mechanical loads where stability and high torque at 2,000 RPM are more important than raw speed.
- Precision: Features the standard 20-bit incremental encoder (1,280,000 pulses/rev) for high-accuracy positioning.
- Durability: Rated IP65 with a built-in oil seal to protect against dust and liquid splashes.
