The Delta ECMA-K11310RS is a 1000W medium-inertia motor designed for high-stability applications. It functions as a precision actuator that balances torque and control, making it ideal for systems where the load might fluctuate or cause mechanical vibration.
Core Functions
- High-Stability Motion (Medium Inertia): Unlike low-inertia motors that can "jitter" under heavy loads, this motors Medium Inertia design provides a built-in mechanical dampening effect. This ensures smooth movement even when the load is heavy or unbalanced.
- Ultra-Precise Positioning: Equipped with a 20-bit incremental encoder, it provides 1,280,000 pulses per revolution. This allows for extreme accuracy in positioning and stable rotation even at speeds as low as 1 RPM.
- Constant Torque Delivery: It delivers a steady 4.77 Nm of torque (peaking at 14.32 Nm). This is significantly higher torque than a standard 1kW low-inertia motor, making it better for "pushing" or "lifting" tasks at 2000 RPM.
- Advanced Suppression: When paired with its drive, it utilizes Automatic Vibration Suppression to cancel out low-frequency mechanical shaking and Auto-Notch Filters to eliminate high-frequency resonance.
Typical Applications
- CNC Lathes & Milling: Used for axis control where cutting forces require high torque and stability.
- Printing & Textile Machinery: Ideal for maintaining constant tension in winding/unwinding processes.
- Automated Assembly: Perfect for pick-and-place robots that handle varying weights.
