Modern engineering challenges demand compact, high-performance motion systems. ECM’s new harmonic drive servo motor—nicknamed the Eight Ball—delivers exceptional torque density, precision, and efficiency in a lightweight, space-saving design.
Challenge
Industries such as robotics, automation, medical devices, and aerospace are constantly pushing the boundaries of performance and efficiency. However, engineers in these sectors face a common set of challenges:
- Space Constraints: Traditional servo motors can be bulky, limiting integration possibilities.
- Weight Sensitivity: Every gram matters in aerospace and medical devices, where lighter components reduce inertia and power consumption.
- Torque Density: Applications require high torque output without sacrificing compactness.
- Precision & Reliability: Advanced tasks demand smooth, accurate motion control with minimal cogging and robust feedback mechanisms.
Solution
ECM PCB Stator Technology’s new High-Torque 50:1 Harmonic Drive—nicknamed the ‘Eight Ball’—directly tackles these challenges by offering an ultra-compact, lightweight, and torque-dense servo motor that fits seamlessly into space-constrained applications.
Key Innovations
Compact & Lightweight Design
The Eight Ball’s ultra-compact dimensions (2.95″ x 3.35″ x 1.96″) and minimal weight (only 0.57 kg/1.26 lbs) allow seamless integration into space-constrained systems, reducing overall system complexity.
High Torque Performance
Despite its compact form factor, the motor delivers a remarkable 33.9 Nm of peak torque and 18.8 Nm of continuous torque, powered by an integrated 50:1 harmonic drive for robust performance in demanding applications.
Precise Control
A dual encoder system provides closed-loop feedback, ensuring smooth, cog-free operation with accurate speed and position control—essential for high-precision tasks.
Efficiency Benefits
The innovative design not only enhances performance but also minimizes inertia and energy consumption, making it an ideal solution for applications where efficiency is critical.
Real-World Applications
