CS Type Closed Loop Stepper Motor Hollow Rotary Actuators
The CS type of GIGAGER Hollow Rotary Actuator is a line of products that combine a high rigidity hollow rotary table with a dedicated closed loop stepper motor and driver package. It retains the ease of use of a stepper motor, while also allowing for highly accurate positioning of large inertia loads.
• Integrated actuator and stepper motor makes design easier
• Large-diameter hollow output table
• Stepper motor provides excellent performance
• High precision
• Agile responsiveness
• Stability at low speeds
• High torque output
• Simple setting
• Pulse Input, 4-digit display, 4-digit function button type driver
1. What is the Hollow Rotary Actuator?
The Hollow Rotary Actuator is a brand-new kind of rotating load device packed with motor and driver. Incorporating high transmission efficiency, high precision, high rigidity, and high cost performance, it combines the advantages of the servo motor, cam indexer and DD motor, obtaining a balance between these three products.
With high-precision gear structure and radial bearings, torque and rigidity improved, the loading become more stable. It can make segments at any angle with servo motor or stepping motor, which can meet the digit control that the cam indexer cannot achieve. The positioning accuracy is comparable with the direct drive motor which can realize the positioning of the inertia load in a short time.
2. What is the product features of CS type Hollow Rotary Actuator?
• Improve Reliability and Reduce Cost Through Direct Connections
The equipment table and robot arm can be directly mounted on the output table of Hollow Rotary Actuator. It can save the time and cost for mechanical design, parts allocation, belt debugging, etc., which compared with the use of mechanical parts such as pulleys and belt.
• Ideal Alternative to DD Motor and Cam Indexer
GIGAGER Hollow Rotary Actuator takes the advantages of servo motor, cam indexer and DD motor, making the indexing at any angle and high performance.
• High Precision Positioning without Backlash
Non-backlash, repetitive positioning accuracy up to ±5 arc seconds, positioning accuracy ≦ 2 arc min.
Note: The repetitive positioning accuracy is measured at a constant temperature (normal temperature) under a constant load.
• Large Diameter Hollow Structure Makes Wiring and Piping Possible
Wiring and piping are more convenient and simple, and the advantages of this feature are particularly prominent in complicated wiring and piping environments.
