High Dynamic AC Servo Motor 60mm Low Inertia- Suzhou Retek Electric Technology Co., Ltd.

60mm Low-Inertia AC Servo: Rapid Acceleration and Deceleration

The 60mm Low-Inertia AC Servo Motor is designed with a small rotor diameter and a longer axial length (high L/D ratio). This design drastically reduces the rotor's Moment of Inertia (Jm).

A low inertia rotor enables extremely high acceleration and deceleration rates (rad/s2) with minimal current draw, making it ideal for tasks that require rapid, repetitive point-to-point movements (e.g., pick-and-place, vision systems). While the continuous torque is moderate, the peak torque is often 3 to 5 times the continuous rating, allowing the motor to achieve instant bursts of high force for dynamic motion.

Introduction

Minimal Cogging: Advanced slot/pole combination minimizes detent torque, ensuring smooth, precise low-speed motion.
High Peak Torque: Capable of providing massive transient forces required for instantaneous acceleration.
High Energy Efficiency: Minimal winding losses during acceleration/deceleration cycles due to the small rotor mass.

Frequently Asked Questions

Common Inquiries Regarding Low-Inertia Servos

Q: When should I choose a Low-Inertia over a High-Inertia servo?
A: Choose low-inertia when the load inertia is similar to or less than the motor inertia (JL≤Jm)—i.e., light loads requiring very fast cycle times. Choose high-inertia when driving heavy, high-friction loads (e.g., ball screws, large gantries).

Q: Can I direct-drive a heavy load with this motor?
A: No. The high inertia mismatch would severely limit the acceleration rate. Low-inertia servos are best used for direct drive of light loads or coupled via a gearbox for heavy loads, effectively lowering the reflected load inertia.

Q: What is the highest recommended resolution for the encoder?
A: For high-dynamic systems, the encoder resolution is paramount. We recommend absolute encoders with 20 to 23 bits of resolution (over a million counts per revolution) to ensure precise velocity and position feedback.
