About ECMA-FA1830SS Delta Servo Motor 3000W H , Torque Nm - 19.1 , RPM - 1500
The Delta ECMA-FA1830SS is a heavy-duty 3000W AC servo motor designed for "High-Torque, Low-Speed" applications. Its primary function is to move and hold extremely heavy loads with pinpoint precision.
Core Functions
- High Torque Output: It delivers a massive 19.10 Nm of continuous torque at a rated speed of 1500 RPM. This makes it the "muscle" for heavy industrial equipment that requires consistent force rather than high speed.
- Maximum Load Stability (Medium-High Inertia): The "FA" series features higher rotor inertia. This acts as a stabilizer, preventing the motor from vibrating or overshooting when moving massive mechanical structures like heavy bridge mills or large gantry systems.
- Absolute Position Tracking: Equipped with a 17-bit absolute encoder, it provides 131,072 pulses per revolution. It "remembers" its exact physical location even after a power failure, meaning you never have to perform a "homing" sequence to reset the machine.
- Safety Static Braking: The "SS" suffix indicates an integrated electromagnetic brake. Its function is to lock the shaft firmly in place (with a holding torque of at least 25 Nm) when the power is cut, which is critical for vertical axes to prevent heavy tools from falling.
Typical Applications
- Large CNC Boring & Milling: Ideal for driving the primary axes of large-scale machine tools where cutting resistance is high.
- Heavy-Duty Indexing: Used in rotary tables or tool changers that must rotate heavy workpieces to exact angles.
- Material Forming: Controlling the stroke of industrial presses or large injection molding machines.
Drive Compatibility
This motor is typically paired with the ASDA-A2-3023-M servo drive. This combination allows for advanced functions like E-CAM (Electronic Cam) for synchronized multi-axis motion and Full Closed-Loop Control to eliminate mechanical backlash.

Key Technical Notes
- Medium-High Inertia: The "FA" series is a Medium-High Inertia motor. This provides superior stability for heavy industrial loads that might cause vibrations in low-inertia motors.
- High Torque at Lower Speed: Unlike the 3000W "CA" or "EA" models, this motor is rated for 1500 RPM, allowing it to produce a higher rated torque of 19.10 Nm.
- Integrated Brake: The "SS" suffix indicates it includes an electromagnetic holding brake. This adds significant weight, bringing the total to nearly 50 lbs.
- Mounting: The mounting hole spacing for this 180mm frame is approximately 7.874 inches (200 mm). [1, 2, 3, 4, 5, 6]
Function
This motor functions as a powerhouse for applications requiring heavy lifting or high constant force. Its absolute 17-bit encoder ensures high-precision positioning (131,072 pulses/rev) without needing to home the machine after every power cycle
