Brushless DCV Motor White Paper Cover

Ten Reasons to Consider Brushless DCV Motors in Electric Valve Actuators

Are brushless motors worth the investment?
Brushless DC electric (BLDC) motors have been in use for nearly 50 years but have only recently been employed in smart actuation. By incorporating sophisticated electronics such as responsive motor controllers, BLDC technology offers significant advantages, including superior precision, safer and quieter operation, compact size, and longer equipment life. While BLDC motors require electronics, they are virtually maintenance-free, highly efficient and cost-competitive in smaller torques.

This white paper explains the advantages of BLDC motors in actuation and details the business case for using BLDC-powered actuators in plant systems requiring increased levels of safety and control. You’ll also learn why the benefits they offer in safety, reliability and predictability — at competitive cost — is already driving a trend toward the gradual replacement of most other motor types.

Intrusive vs. Non-Intrusive Electric Actuator White Paper Cover

Intrusive vs. Non-Intrusive Electric Actuators

Is an intrusive or non-intrusive electric actuator right for your application?
Many factors influence the choice of electric actuators, and no single design or feature set meets the need of every application. This paper is designed to make these decisions easier by providing a clear overview of the two major categories of electric actuators:

  • Intrusive — Electromechanical devices with all controls and components typically combined in a single compartment, which simplifies installation and maintenance.
  • Non-Intrusive — Actuators with electronic controls located in a separate sealed enclosure, enabling position and torque limits to be set without opening the control compartment.

The benefits and limitations of each design are detailed in this paper. It also offers guidance on selecting the right type for your site’s application needs and resources. Your unique application is likely to suggest which category offers your site an ideal balance between functionality and cost of ownership.

Built in Self Test White Paper Cover

BIST (Built-in-Self-Test) Features for Electronic Valve Actuators

Do electric rotary actuators require highly trained technicians?
While smart electronic actuators increase performance, they also raise the level of sophistication needed for troubleshooting. Built-in-Self-Test (BIST) features counter this challenge by building diagnostic logic directly into the device, ensuring proper operation and predicting failures before they occur.

In this paper, you’ll learn the key BIST features that will provide you with the assurance that an electric actuator is designed with plant-wide safety and operational integrity in mind. Such devices enable safety system managers to maintain systems at the highest possible safety integrity levels. Asset managers also benefit from reduced maintenance costs and significant improvements in uptime because only those systems reporting BIST-diagnosed or -predicted failures require service.
