White Papers: In depth research


Title Author Date
Understanding programmable automation controllers (PACs) in industrial automation Opto 22 01/25/2007
This paper provides an understanding of how PACs provide in a single compact controller the advanced control features, network connectivity, device interoperability, and enterprise data integration capabilities found in PLC- or PC-based automation controllers. 
DC drive fundamentals 01/12/2007
This paper examines some of the basic characteristics obtainable from DC motors and their associated solid-state controls. 
The world of drives Baldor 11/27/2006
This white paper explores the world of drives used in motion control applications--including inverter, vector, servo and now, linear drives--and explains where each is best used. 
How to choose a digital motion control network G&L Motion Control 07/10/2006
There are so many digital networks available today that the buyer has their hands full trying to pick a digital network to go with. This White Paper helps define reasons why a digital network should be chosen for your control platform, and offers suggestions on how to make the best choice for your motion control applications. 
New technologies for multi-axis drive systems Siemens E&A 06/22/2006
Converting, printing, packaging, paper machines and machine tools are just a few of the various applications that have standardized on multi-axis designs. This White Paper shows how multi-axis drive systems are becoming an increasingly popular method to provide customers with compact, efficient, and cost-effective drive solutions. 
Mechatronic solutions for intelligent motion control Siemens Energy & Automation 04/21/2006
Modular machine building is becoming one of the next challenges of control system builders to make distributed machine control possible. Find out how mechatronic solutions are being used to simplify construction with servo drives and intelligent motion control software. 
Functional safety concepts in motor control Underwriters Laboratories 03/23/2006
The approach for addressing functional safety of embedded software dependent motion controls is becoming a growing concern as programmable components replace traditional electromechanical components in safety-related systems.  
PMSM technology in variable speed applications Automotion Inc. 02/16/2006
When machine designers are called upon to maximize performance in variable speed applications, they often select the permanent magnet synchronous motor (PMSM) over AC induction alternatives. This article examines the typical selection criteria and justification for PMSM technology. 
Understanding linear motor parameters Parker-Trilogy 01/18/2006
This paper will use first principles to develop specifications specifically for three phase, brushless linear servo motors based on fundamental characteristics. It will also develop relationships between certain motor parameters and show how some are dependant on winding type and others are not. 
Closed loop control of stepper motors without position sensor Allied Systems 11/17/2005
This paper presents a patent-pending method to operate stepper motors in closed loop position without position sensors, boosting stepper-motor performance into the range of servomotor performance while maintaining the inherent simplicity of the conventional stepper motor drive system. 
Ironless versus ironcore motor solutions HST-Etel 10/20/2005
This article presents an engineering-based comparison of the two predominant linear motor types, with the objective of providing the knowledge needed to properly specify the correct type of motor for a given application. Real world examples of both motor types (ironcore and ironless) are presented. 
Success with variable frequency drives (VFDs) EASA 08/18/2005
Variable frequency drives offer many benefits, not the least of which is the ability to directly drive variable-speed loads using AC induction motors. This White Paper begins with a bit of theory, then takes a look at how to avoid problems by providing guidelines for ways to gain the benefits of reduced costs and increased success with your production goals. 
Success with variable frequency drives (VFDs) EASA 07/21/2005
VFDs can reduce costs while increasing success with production goals. This White Paper takes a look at how to avoid the problems and gain the benefits, beginning with a bit of theory. 
Keep motor drives ready for production ABB 05/20/2005
This "special to the web" White Paper serves as a guide to keeping motor drives at the ready, and points out what OEM customers should know about mothballing drives and motors due to production slowdowns. 
Influence of the motor feedback sensor on AC brushless servo drive performances Infranor S.A. 02/18/2005
