Harmonic Drive LLC Introduces SHA-CG Hollow Shaft Actuators
Direct Drive Motor Performance in an extremely compact size
Peabody, MA, November 4, 2015 -Harmonic Drive LLC, a leader in high precision motion control introduces new actuators with surface run-out less than 10 microns. The SHA-CG models are the newest offerings in the company's Rotary Acutator product category.
The SHA-CG actuators feature a compact, hollow shaft configuration for design versatility in demanding applications. Ideal for machine tool applications, the SHA Series of brushless actuators provide high torque for fast acceleration and positioning. SHA-CG actuators are composed of a Harmonic Drive CSG zero-backlash gear combined with a brushless servomotor with an encoder resolution at the output up to 20,971,520 pulse/rev.
The actuators are also available with an optional brake. Positional accuracy better than 1 arc-min and repeatability better than ±5 arc-sec is achieved while delivering up to 3,400 N m of torque. A robust cross-roller bearing allows mounting of large loads directly to the actuator without the need for additional support.
The SHA-CG has a Torque to Weight ratio as much as 8 times greater than comparable housed direct drive motors, and a Torque to Volume ratio as much as 6 times greater. This allows for a more compact and light-weight machine design.
Known for its expert engineering and manufacturing, Harmonic Drive LLC products are relied upon every day for precision motion control.
SHA-CG Specifications:
* High Accuracy: Zero-backlash Harmonic Drive® gear reducer
* Hollow Shaft diameter: 17-45mm
* Available in 4 sizes, 20, 25, 32, 40
* Maximum speed up to 120 rpm
* Design: Compact, flat, hollow shaft

uEye XC AUTOMATICALLY PERFECT IMAGES
Combining the ease of use of a webcam with the performance and reliability of an industrial camera? The uEye XC autofocus camera from IDS Imaging Development Systems proves that this is possible. Its high-resolution imaging, simple setup and adaptability make it an invaluable tool for improving quality control and streamlining workflows in industrial settings - especially for cases where users would normally employ a webcam. The uEye XC autofocus camera features a 13 MP onsemi sensor and supports two different protocols: USB3 Vision, which enables programmability and customization, and UVC (USB Video Class). The UVC functionality enables a single cable connection for easy setup and commissioning, while delivering high-resolution images and video. This makes the uEye XC camera an ideal option for applications that require quick setup and need to manage variable object distances. Additional features such as digital zoom, automatic white balance and color correction ensure precise detail capture, which is essential for quality control.
