About ECMA-K11315RS Delta Servo Motor 1500W M , Torque Nm - 7.16 , RPM - 2000
The Delta ECMA-K11315RS is a 1500W medium-inertia motor designed for high-stability motion control in 400V industrial environments. It functions as a powerful actuator that balances precision with the ability to handle mechanical "noise" and load fluctuations.
Core Functions
- Load Stabilization (Medium Inertia): The primary function of the "K" series is to provide a higher rotor inertia. This acts as a mechanical buffer, preventing the motor from vibrating or overshooting when moving heavy or resonance-prone loads.
- High-Resolution Feedback: Equipped with a 20-bit incremental encoder, it provides 1,280,000 pulses per revolution. This allows for extreme accuracy in positioning and ensures smooth, jitter-free rotation even at very low speeds.
- Constant Torque Delivery: It delivers a steady 7.16 Nm of torque (peaking at 21.48 Nm). This allows it to "push" or "pull" heavy mechanical parts with more authority than a low-inertia motor at 2000 RPM.
- Active Suppression: When paired with its drive, it utilizes Auto-Notch Filters and Vibration Suppression algorithms to automatically detect and cancel out mechanical resonance in real-time.
Typical Applications
- CNC Lathes & Milling: Ideal for feed axes where cutting resistance varies.
- Textile & Paper Machines: Used for maintaining precise tension in winding/unwinding.
- Material Handling: Driving conveyor systems or pick-and-place robots that move varying weights.
Key Technical Note
- No Brake (RS Series): This model does not include a holding brake. If you are using this on a vertical axis (where the load could fall when power is lost), you should use the SS version (ECMA-K11315SS) instead.
The Delta ECMA-K11315RS is a 1500W medium-inertia motor from the 400V class, designed to provide a balance of high torque and motion stability.
