Electric motor driven systems (MDS) account for over 50% electricity consumption. MDS can be inefficient and costly to operate if they are not properly designed, selected, and maintained.

Facility and operation managers can avoid unnecessary energy wastage by selecting MDS that are well suited to their applications and making sure that they are well maintained.

Cost-effective design, operation, and maintenance of a MDS requires attention not just to individual piece of equipment but to the total system performance which necessitates an analysis of the interaction of both the supply and demand sides. 

At the end of this course, participants will be able to:

  • Gain in-depth knowledge and skills to identify and evaluate energy conservation opportunities involving motor-driven equipment
  • Implement facility energy management programme involving motor-driven equipment
  • Familiarise with current and emerging energy-efficient motors, the associated power electronics, and control technologies
  • Design energy efficient motor-driven systems through theory-based calculations, and the appropriate sizing and selection of energy efficient components, such as fans and pumps
  • Evaluate system performance of MDS taking account of interactions of both supply and demand sides, and be able to deploy cost-effective measures to improve energy performance
  • Conduct performance evaluation and energy audit of motor-driven systems through authentic learning with hands-on practical sessions

Who Should Attend

  • SCEM and other energy professionals
  • Plant and facility managers and engineers who operate and maintain MDS
  • Mechanical & electrical engineers who design and select MDS
  • Qualified engineers who aspire to become an EEO assessor in motor driven systems
Prerequisites
  • Bachelor degree in engineering or engineering diploma with 2 years of relevant working experience
