This course is structured specifically to provide know how knowledge of induction motor and variable speed drives (VSD). More than 80% of the machines in industry run with the induction motor. For two reasons, starters are used for the motor, one for protection of people and second for protection of motor itself. Even at this moment, there are still many motors running with electromechanical starters such as direct on line, star- delta etc. But recently, due to the rising concern in electric energy and the craving need for electric energy saving and better performance, VSD is gradually replacing electromechanical starters. In this course, the participants will be first given a thorough explanation on the induction motor to appreciate the importance of VSD. Secondly, the concept of VSD will be explained together with the sizing and selection procedures. The advantages and limitations of the VSD will be clearly explained. Last but not least, new problems found in power system with VSD installed will be explained with their effect and mitigation issues. Practical sessions on setting up of VSD system, parameter setting, and troubleshooting and many more are included in this workshop.

Target Audience:
Engineers, Technicians and Supervisors who are involved in the design, operation and maintenance of induction motor and inverter. Recommended also for those who are fresh and interested to gain knowledge on inverter for induction motor.
