ECMA-C11010RS DELTA A2 Series AC Servo Motor 1 kW

Product Overview

The ECMA-C11010RS (ECMAC11010RS) is a high-performance AC Servo Motor from Delta's renowned ASDA-A2 series, engineered for high-speed and high-precision motion control applications. Delivering a robust 1 kW of power at a rated speed of 3000 r/min, this motor is an industry staple for applications requiring rapid acceleration and precise positioning, such as CNC milling, high-speed pick-and-place robotics, and automated textile machinery. The motor features a 20-bit incremental encoder, providing a resolution of 1,280,000 pulses per revolution, which ensures exceptionally smooth motion and minimizes torque ripple. Encased in a 100 mm frame, this model is built for durability with an integrated oil seal, though it is configured without a mechanical brake, making it ideal for horizontal axes where high dynamic response is the primary requirement.

Suffix & Part Number Breakdown

The ECMA-C11010RS follows Delta's systematic coding for the A2 Series to define its mechanical and electrical characteristics:

• ECMA: Electrical Commutation Motor (AC Servo).

• C: Rated Voltage / Rated Speed (220 V / 3000 r/min).

• 1: Encoder Type (20-bit Incremental Optical Encoder).

• 10: Motor Frame Size (100 mm).

• 10: Rated Output Power (1.0 kW).

• R: Shaft and Seal Type (Keyway with fixed screw hole, without brake, with oil seal).

• S: Standard Shaft Diameter and Connector.

Technical FAQs

In what scenarios is the "Non-Brake" (R) version preferable over the brake version?

The ECMA-C11010RS is preferred for horizontal motion applications where the load does not need to be held in place during a power-off state. By omitting the brake, the motor has lower mass (4.3 kg vs. 5.5+ kg for brake models) and a shorter physical length, allowing for higher acceleration rates and easier integration into compact machinery where gravity-induced "back-driving" is not a concern.

How does the 20-bit encoder affect the performance of the A2 series?

The 20-bit resolution allows the servo drive to achieve superior low-speed stability and extremely precise position control. In the ASDA-A2 system, this high-resolution feedback is also utilized to implement advanced vibration suppression and notch filters, which help stabilize machines with low mechanical stiffness or high resonance.

Is this motor compatible with the ASDA-B2 series drives?

While the ECMA series motors are primarily designed for the ASDA-A2 series drives to take full advantage of the 20-bit feedback and E-CAM functions, they are often compatible with ASDA-B2 drives. However, the drive's control parameters must be correctly mapped to the 20-bit encoder feedback to ensure stable operation.

Engineering & Installation Guide

• Oil Seal Protection: The integrated oil seal is designed to prevent the ingress of gearbox oil or contaminants into the motor housing. To ensure longevity, avoid "submerged" operation where the oil level is higher than the shaft center. Regularly inspect the shaft area for any leakage, as dry-running the oil seal can cause friction-related heat damage.

• Radial and Axial Loads: When installing pulleys or couplings using the keyway, avoid excessive hammering on the shaft, which can damage the sensitive 20-bit optical encoder disk at the rear of the motor. Use the fixed screw hole on the shaft end to pull couplings into place smoothly.

• Cabling and Grounding: Due to the high-frequency switching of the AC servo drive, always use shielded power and encoder cables. Ensure the motor frame is grounded to the machine base and the cable shields are grounded at the drive side to prevent "ghost" pulses or encoder signal interference which can lead to position errors.
