Course Description:

This course is part of the Electrical Equipment Specialist Certificate program. Although it can also be taken on its own. 

Maximum efficiency, reliability, and longevity of the various types of motors, and variable-speed drives are of great concern to many industries. These objectives can only be achieved by understanding the characteristics, selection criteria, common problems and repair techniques, preventive and predictive maintenance. This course is a MUST for anyone who is involved in the selection, applications, or maintenance of motors, and variable-speed drives. It provides the latest in technology. The course covers how this equipment operates and provides guidelines and rules that must be followed for a successful operation. Their basic design, operating characteristics, specification, selection criteria, advanced fault detection techniques, critical components as well as all maintenance issues are covered in detail.

The PDDP Distance Education program works as follows:

  • Once you register for this course, you will be sent a login username and password for our online distance website.

  • You will receive the course notes in hard copy through the online website, you will receive a set of notes each week covering the course material.

  • A one hour video-conference session will be conducted by your instructor each week (if required). The objective of this session is to assist in solving the assignments, as well as answer student questions that should be sent to instructor early enough prior to the meeting time. In addition with being able to communicate with the instructor, you will also be able to communicate with other students in the same class and watch their questions being answered as well. (A high speed internet connection is strongly recommended for this feature).

  • Each set of exercises can be completed and submitted by the indicated date and your completed exercise will be marked online and and returned by your instructor.

  • To gain the most from your course, it is highly recommended that you participate fully in all discussions and exercises. Please remember that each course has a form of quiz or exercise at the end to test your understanding of the material. You will be informed of these dates when you receive the course schedule.

*Course commencement date is subject to instructor availability.
