Content Training Methodology
The Course

AC motors represent industry's workhorse in small, medium and large size applications. It is no exaggeration to suggest that more than 50% of the energy consumed worldwide is converted by AC motors into work and these motors are controlled by drives. These drives are ever increasing more intelligent, electrical and their monitoring and operation can be integrated with the plant's SCADA system. Understanding maintenance and troubleshooting procedures of such vital industrial equipment means that reduced downtime and increased productivity are the immediate benefits for the company and its management. Equally important, the protection requirements along with their function and integration with the overall system ensures that such expensive apparatus, requiring high capital investment, is well guarded against failures further offering safety for operations personnel as well. The seminar addresses the three topics mentioned above for both AC motors and their drives.

The Goals
The objectives of the seminar are:
  • To present the operation and construction of AC electrical motors and the electrical drives based on modern state-of-the-art inverter technology, and their characteristics that need to be matched with those of loads.
  • To discuss maintenance procedures both for motors and drives following well-established industrial procedures as outlined in standards.
  • To familiarize with troubleshooting methods for both motors and drives following methodologies that have been developed by manufacturers in order to reduce downturn time dramatically.
  • To become familiar on how to utilize single-line drawings and other documentation to successful perform commissioning, maintenance and troubleshooting.
  • To analyse case studies and learn from such experience.
The Process

The latest educational methods and strategies will be employed. The seminar is designed to maximize delegate benefit from the outset and any specific goals of each participant will be discussed to ensure needs are fulfilled as far as possible. Questions are encouraged throughout the day and at the daily wrap-up sessions. This provides opportunities for participants to discuss with the presenter and other delegates specific problems and appropriate solutions. All delegates take away a detailed and comprehensive copy of the material presented; therefore minimal note taking is encouraged to ensure maximum participation and attention.

The Benefits
At the end of the seminar, each delegate will:
  • Understand the operation and construction of AC electrical motors and the electrical drives based on modern electronics technology.
  • Be able to explain their characteristics and the need to match various load needs.
  • Become more confident on how to maintain both motors and drives following well-established industrial procedures as outlined in standards.
  • Become familiar with troubleshooting methods for both motors and drives following methodologies that have been developed by manufacturers in order to reduce downturn time dramatically.
  • Learn how to utilize single-line drawings, and other documentation to successfully perform commissioning, maintenance and troubleshooting of both motors and drives.
  • Become exposed to industrial standards and case studies so that to be able to apply this knowledge in the industrial plant as quickly and efficiently as possible.
The Results

In many onshore and offshore industrial and commercial plants, automation of any process and associated control relies heavily on motors and their drives. The technical skills of engineers and technical managers as far as the operation, maintenance and troubleshooting of such important industrial equipment are vital for the efficient and cost effective operation of the plant with minimum downturn. These skills, as technology makes ever fast advancements need to be acquired and employees need training on the latest technologies and methods of motor drives and control in order to offer best solutions for the enterprise. Maintenance and operation of the plants on an efficient and reliable manner rely on strong skills of employees. The seminar addresses the fundamental topic of the key technology associated with the factory automation, i.e., motors and variable speed drives.

The Core Competencies

At the end of the seminar, the delegates will have confidence and fully understand how the motors are designed and controlled using the latest technology of electric drives. Exposure to industrial standards and industrial state-of-the-art computer software used for commissioning, testing, and operation of these systems is also provided, giving the delegates the necessary knowledge and experience to make improvements in their own work practice should these are needed.
