With regard to accuracy, a typical servo motor is accurate to about +- 0.02 degrees, whereas a stepper motor is accurate to +- 0.005 degrees. Responsiveness The last criteria I would consider is the responsiveness of the application. Stepper motors, by design, are quick to change position—...
The current state of the art in servo systems, their performance characteristics, ultimate performance limitations, optimal design and selection criteria are discussed for high-speed high-precision incremental motion control applications such as assembly machines and x-y table based machines....
Press Selection Tool AIDA Presses That Meet Your Criteria This filtering tool, provided by AIDA, helps to identify which presses best meet a certain set of requirements. Selection in the four categories of Application, Tonnage, Stroke Length, and Bed Size help narrow your search for a stamping ...
Unlike a stepper motor functioning as an open-loop mechanism, a servo motor is merged with a controller and a feedback device into a closed-loop system. In the arrangement, the engine produces kinetic energy, turning its shaft to cause the driven machinery to rotate clockwise or anticlockwise....
1. Selection of motor size The three most important criteria when starting with the motor are: Speed Torque Rotor inertia. The first two are pretty obvious and are typically calculated using "sizing" programs that are offered by various manufacturers. In these programs you can enter the types ...
To provide maximum transparency, the Siemens EcoTech Profile (SEP) were created for all Siemens EcoTech products. It is a Siemens-created, standardized product data sheet which gives insight about the product performance in environmental relevant criteria as well as about interpretation and comparison...
Selection Criteria for Servo Motor Drives The power density and acceleration characteristics of the ac servo drive are being recognized as being superior to those of the dc counterpart. The ac serv... R Krishnan - 《IEEE Transactions on Industry Applications》...
programming language which evolved from Compumotor's X-language. This popular language provides both ease- of use and the ability to program complex motion. UL-Recognized Microstepping Systems Today's laboratory and factory automation products face increasingly stringent performance and safety criteria. ...
Suppliers seek advantages for their servo drive lineups in system-level criteria including control performance, connectivity, ease of use and cost. Higher performance and higher precision control will always be sought after for some machine functions. However, given the strides already made in digital...
After h0 is selected based on Trumpler’s criteria as given in Eq. (A.4), Eq. (A.5) is given as the eccentricity (e) [1]. This value is used in Eq. (A.6) to define the maximum film thickness (hmax). Dimensionless relative eccentricity (ε) is found by using Eq. (A.7), ...
