Feedback Sensors Keep Servo Motors on Target
Author: Gene Matthews, product manager for Kollmorgen
Fundamentally a servo system can perform no more accurately than the accuracy of the feedback device controlling it. In addition, errors in speed or position can be introduced into the system by the less than perfect mechanisms that transfer the motor power to the load. Environmental factors like electrical noise or temperature may also introduce positioning errors. Sometimes the errors are acceptable. More frequently, however, they are not. After all, servo motors can be expensive, and the expectation is that they will be the most reliable and accurate of all positioning devices.
When it comes to high-performance servo applications, feedback devices fall into several different categories. In this white paper, learn how each offers unique advantages and disadvantages, both electrical and mechanical, which make one better suited for a particular application than another.
Motion, Drives and Motors: Usage and Application Trends
An electronic survey of our readers was conducted in February 2013 in order to identify usage and application trends of motion, drives and motors among the industrial machine builders that comprise our readership. In this Market Intelligence Report, you will find detailed survey results with key findings summarized. The survey consisted of the following questions:
1. What types of motors do you primarily use?
2. If you use servo motors are they mostly for digital or analog?
3. If you use steppers are they closed loop or open loop?
4. Rate the importance of these performance characteristics for your drive requirements
5. If you use a digital bus for motion control, which ones do you use?
6. What update rate is required?
7. What is the biggest motion control challenge for you?
Five Things To Consider Before Buying Spiral Bevel Gear Drives
Author: George Abbot, product manager for Mitrpak
Spiral bevel gear drives play a critical role where motive force must be transferred "around a corner" and this new technical brief is written to help you obtain the most suitable spiral gear drive for your specific requirements. It touches on variables such as lead times, costs, reliability, ordering ease, applications expertise and the types of customization solutions that are available. It is organized around the key questions you'll want to discuss with a prospective vendor. This white paper will help you determine which spiral bevel gear drives are the optimum choice for your unique application.
Why Pay for More Than You Need?
Author: Dunkermotor Senior Applications Engineer Jay Becker
Today's technology brings servo manufacturers many options when it comes to designing their motor drives and controls. With all the different possible functions that can be implemented in a servo drive, many manufacturers are tempted to pack them all into one "full-featured" product. This can be a problem however for the OEM when it comes time to select the right one for their application. This white paper describes the different levels of capability of Dunkermotoren's servo motor/drives.
- Motors include two-stage, worm-geared motors and gearboxes with special input units for synchronous and asynchronous IEC standard motors and IE3-efficiency-class motors.
- Stages claim accuracy to 20 arc sec, with 8 arc sec bi-directional repeatability, 30 rpm maximum speed, and 360° continuous or optional limited travels.
- iPOS3604 VX intelligent drives, and provides connectors (motor, encoder feedback and I/O signal) for each drive through a CANbus link.
- Currently being used in small axis optical metrology machines, the RS8 nut is the smallest drive in the RS line, yet it provides the same axial thrust (100 Newtons) as the next larger size drive unit
