ECMA-F11830RS | DELTA | Moteur servo AC

Description

Designed for high-precision motion control applications, the Delta Electronics ECMA-F11830RS is a high-performance AC Servo Motor within the ASDA-A2 Series family, delivering a nominal power output of 3.0 kW. This industrial-grade rotary actuator converts electrical energy into precise mechanical rotation, utilizing a 20-bit incremental encoder to feedback high-resolution position data to compatible servo drives. Engineered with a robust 180mm frame size, this electrical commutation motor (ECM) operates on a 220V rated voltage at a base speed of 1500 r/min. It is constructed without a mechanical brake and features an integrated oil seal to maintain reliable operation in demanding environments containing fluids or airborne mist.

Key Technical Features

• 20-Bit Incremental Encoder: Provides 1,048,576 pulses per revolution (ppr) for extreme positioning accuracy and low-speed stability.
• Integrated Oil Seal: Provides a physical barrier against liquid splashes and industrial environmental contaminants along the drive shaft.
• Optimized Electrical Commutation: Ensures high efficiency, low cogging torque, and dynamic acceleration performance across the entire speed envelope.
• Keyway with Screw Hole: Standardized shaft interface featuring keyway execution (Type R) and an integrated screw thread for secure coupling alignment.

Industrial Applications

• Multi-axis CNC machining, milling, and precision metal cutting machinery.
• High-speed industrial packaging, wrapping, and bottle-filling systems.
• Material handling automation, gantry systems, and robotic pick-and-place units.
• Precision metal forming, stamping, and automated bending presses.

Technical Specifications

Connections and Interfaces

Alternative Models & Compatibility

The ECMA-F11830RS servo motor is designed specifically to interface with Delta's ASDA-A2 Series and ASDA-M Series servo drives rated at 3.0 kW (specifically the ASD-A2-3023-L or ASD-A2-3023-M). If transitioning from older ECMA-F11830SS (which features a standard keyway without screw hole), the physical frame, electrical performance, and wiring pinouts remain fully identical, allowing a direct drop-in mechanical replacement.

Application Pitfalls & Engineering Notes

Due to the absence of an integrated holding brake on this specific model (designated by the 'R' code in the suffix), this motor must not be used for vertical axis applications without an external, independent mechanical brake setup. In vertical installations, a sudden power failure or drive de-energization will result in immediate gravitational descent of the load. Additionally, ensure the oil seal is kept clear of abrasive dry dust particles, which can accelerate seal lip wear and lead to fluid ingress.

Commissioning & Wiring Tips

To maintain signal integrity of the high-speed 20-bit feedback system, always use Delta's factory-assembled, double-shielded twisted-pair encoder cables. Run motor power cables and low-voltage encoder signal cables in separate conduits or wire trays separated by at least 100 mm. Improper grounding of the motor frame to the electrical panel backplate can introduce high-frequency PWM switching noise, triggering drive communication faults (AL011 or AL012).
