Product Overview
The Delta Tau ECMA-LA1875R3 is a high-performance permanent magnet AC servo motor designed for precision motion control applications across industrial automation, robotics, and CNC machinery. As part of Delta Tau’s ECMA series, renowned for reliability and versatility, this model delivers 7.5kW of continuous power and is engineered to integrate seamlessly with Delta Tau’s ASD-A2 and ASD-A3 series servo drives. Its core functionality includes precise torque and speed regulation, making it ideal for demanding tasks such as high-speed positioning, synchronized multi-axis motion, and dynamic load handling.

 

Key to the ECMA-LA1875R3 is its 20-bit incremental encoder, which ensures exceptional positional accuracy (16,777,216 pulses per revolution) and smooth low-speed operation . The motor supports 220V AC input and features a rugged construction with IP65 environmental protection, enabling reliable performance in dusty or wet industrial environments. Its compact design (180mm frame size) and standardized mounting flange simplify retrofitting into existing systems, while its compatibility with advanced communication protocols like EtherCAT and CANopen enhances integration with modern automation architectures.

 

For industries requiring high throughput and minimal downtime, the ECMA-LA1875R3 offers fast acceleration/deceleration cycles (up to 3,000 r/min in 7ms) and built-in vibration suppression technology to reduce mechanical wear . This makes it a preferred choice for applications like automotive assembly lines, packaging machinery, and semiconductor manufacturing.

Key Features and Benefits

 

  1. Precision and Stability
    The ECMA-LA1875R3’s 20-bit encoder ensures micron-level positioning accuracy, critical for applications like PCB drilling or robotic assembly. Its auto-tuning algorithm dynamically adjusts gain parameters to minimize vibration and overshoot, even under varying loads .
  2. High Dynamic Performance
    With a peak torque of 47.74N·m and rapid acceleration capabilities, the motor excels in high-speed pick-and-place systems and CNC machining centers where split-second responsiveness is essential.
  3. Rugged Design
    The IP65-rated housing and reinforced bearings withstand harsh conditions, while the anti-corrosive surface treatment extends lifespan in challenging environments such as steel mills or food processing facilities .
  4. Flexible Integration
    Compatible with Delta Tau’s ASD-A2/A3 drives, the motor supports advanced motion control features like electronic cam profiling (E-CAM) and gantry synchronization, enabling complex motion trajectories without external controllers . Its plug-and-play compatibility with EtherCAT reduces wiring complexity and system setup time.
  5. Energy Efficiency
    The motor’s permanent magnet design minimizes power loss, while regenerative braking (via compatible drives) recovers energy during deceleration, lowering operational costs.
