Low Inertia Series Servo motor
The low-inertia Series is a lineup of AC servo motors designed for high-speed, high-responsiveness motion control applications. These motors feature a small-inertia rotor, enabling rapid acceleration and deceleration, precise positioning, and excellent dynamic performance. The series is commonly found in applications such as robotics, pick-and-place machines, indexing systems, and high-speed assembly lines.
Key Features
Low Rotor Inertia: The rotor’s moment of inertia is minimized, enabling faster acceleration/deceleration and improved system responsiveness.
High Dynamism: Designed for high-speed motion axes where quick changes in direction or speed are required.
Compact Size with High Power Density: Despite its low inertia, the Low-Inertia Series provides adequate torque for servo applications in a compact frame (e.g., 0.05-0.75 kW per the manufacturer).
Precision Feedback: Typically includes high-resolution encoders for tight positioning accuracy and repeatability.
Servo Drive Compatibility: Designed to work with servo drive systems that support motion profiles, tuning, and closed-loop control.
Typical Specifications
Power Range: Approximately 0.05 kW to 0.75 kW (as listed by the manufacturer).
Motor Type: Brushless AC servo motor with feedback device (encoder/resolver).
Applications: High-dynamic axes in automation, electronics manufacturing, and light industrial robotics.
Advantages in Motion Systems
Faster Response Time: Low inertia allows the motor to accelerate or decelerate more quickly, reducing cycle time and improving throughput.
Improved Accuracy: With less inertial load, the servo system can achieve tighter control, lower overshoot, and better settling times. This is particularly beneficial in applications with frequent start/stop or directional changes.
Energy Efficiency: Because less mass needs to be accelerated, energy consumption during dynamic motion may be lower than with higher-inertia motors.
Compact Footprint: The design allows integration into compact machine frames or axes with limited space.
Application Highlights
Pick & Place Robots: High-speed pick-and-place machines that require quick, precise movement of lighter payloads.
Indexing Tables & Rotary Stages: Applications where the motor must repeatedly accelerate, stop, and reverse with high precision.
Assembly Machines: Light-duty assembly lines where positioning accuracy and fast cycle times are critical.
Automation Modules: Smaller axes in multi-axis systems (e.g., feeders, conveyors) where weight and space are constrained.
The Low-Inertia Series is a high-performance servo motor solution for systems requiring dynamic motion, a compact design, and precise control. By selecting a low-inertia Series motor, system designers can achieve faster motion, better control, and higher overall productivity.
