Variable Speed Drives (VSD)
Course Description
The continuous advancement of power electronics technology provides significant opportunities for the industry to operate all process control equipment and associated motors with better efficiency and higher reliability than ever before. Variable speed motor drives are widely used in the industry to continually adjust the speed and torque of motors to achieve the required control for automation with the most efficient approach possible. This seminar has been acknowledged by delegates for it: • Offers a strong practical background to the understanding of all the concepts associated with variable speed drives technology. • Covers many applications, including the selection, handling, commissioning and operation of the said technology. • Ensures that delegates fully understand the difference between soft-starting and VSD technology which are commonly mistaken and clears all misconceptions attached to the technology. • Discusses case studies and showcases software technology for easy configuration of drives and their integration with the industrial plant.

Training Objective

The main objectives of the seminar can be summarized as follows:

  • To ensure attendees understand the basic components of an electric drive and the associated solid-state converter circuits.
  • To learn the various types of motors and the related applications in an industrial process.
  • To familiarize with various speed control methods and the important braking of motors, a capability of advanced hardware that can make huge potential savings in a large plant.
  • To discuss the future of this technology and the market trends.

Target Audience

The seminar is designed for electrical/electronic engineers and technicians, maintenance personnel, plant technical staff, and supervisors who have some basic knowledge of electrical engineering and wish to expand their knowledge and learn the state-of-the-art in variable speed motor drive technology and the issues associated with it. Mechanical and chemical engineers will also benefit as most industrial processes, if not all, are controlled and adjusted using this technology. From the management point of view, significant savings in a very short payback period can be justified with the technology presented in this seminar.

The emphasis is placed on practical concepts used widely in industrial environments so that the presented material is more relevant for practical use by the attendees.

Training Methods

The latest educational methods and strategies are employed. The course is designed to not only give the required fundamental knowledge but also to provide a strong background for all attendees towards practical industrial applications.
