Moteur servo AC série DELTA ECMA-C10807SS ASDA-A2

High-Performance Rotary Motion Overview

The ECMA-C10807SS (ECMA-C10807SS) is a heavy-duty synchronous AC servo motor designed and manufactured by Delta for high-precision motion control within the ASDA-A2 system architecture. Operating at a rated output of 750 W, this industrial electrical commutation motor delivers high torque density and exceptional dynamic response across its entire speed range. For demanding applications such as multi-axis CNC machine tools, automated packaging systems, and precise pick-and-place robotic arms, the ECMA-C10807SS minimizes positioning errors and cuts unexpected machine downtime through its integrated high-resolution encoder and rugged mechanical build. Its built-in holding brake ensures reliable positioning stability and safe load holding during emergency stops or power loss scenarios.

Technical Knowledge Base & Common Inquiries

What are the functional benefits of the integrated 20-bit incremental encoder?

The 20-bit optical encoder delivers a resolution of 1,048,576 pulses per single revolution. This ultra-high resolution significantly enhances low-speed stability, minimizes velocity ripple, and allows the matched ASDA-A2 servo drive to execute precise micro-positioning loops, which filters out structural resonance on the mechanical axis.

What is the correct operation sequence for the integrated holding brake?

The built-in electromagnetic brake is strictly a holding brake designed to lock the motor shaft in position when the system is unpowered or in an emergency stop state. It must never be used to decelerate a spinning motor. The servo drive's brake output relay control must be interlocked with the servo-on signal to release the brake only after the motor fields are energized.

How does the integrated oil seal protect the internal components?

The heavy-duty oil seal installed on the front flange prevents cutting fluids, gear oil mist, and moisture from penetrating along the motor shaft into the bearings and encoder housing. This makes the motor suitable for mounting directly onto oil-lubricated gearboxes or CNC spindle heads.

Field Commissioning & Safety Guidelines

• Radial and Axial Shaft Load Limits: During mechanical coupling to lead screws or belt pulleys, ensure the shaft alignment is within specified tolerances. Excessive parallel misalignments exceed the structural limits of the front bearing, accelerating wear on the oil seal and triggering premature mechanical binding. Do not strike the shaft with hammers during installation as this shatters the internal glass encoder disk.

• Thermal Dissipation Protocols: Install the motor onto a metal mounting plate that acts as a heat sink (minimum recommended size: 250 mm x 250 mm x 6 mm aluminum). Ensure ambient air around the 80 mm frame does not exceed 40 deg C. Clean any accumulated dust or grease off the motor housing regularly to maintain optimal convective cooling.

• Shielded Power and Feedback Routing: Run the heavy-duty power cable and the sensitive encoder signal feedback cable in separate conduits or energy chains separated by a minimum of 100 mm. Ground the braided cable shields at the drive enclosure to avoid high-frequency PWM switching noise from corrupting the encoder data packets.
