INTRODUCTION:
  • It is estimated that electrical drives and other rotating equipment consume about 50% of the total electrical energy consumed in the world today (and this figure increases to 70% if you only consider industry.) The cost of maintaining electrical motors can be a significant amount in the budget item of manufacturing and mining industries. This course gives you a thorough understanding of electrical motor’s protection, control and maintenance and gives you the tools to maintain and troubleshoot electrical motors.
  • You will gain a fundamental understanding of the protection, control and maintenance of electric motors and drives. Typical applications of electric motors in manufacturing, materials handling, process control are covered in detail. The concluding section of the course gives you the fundamental tools in troubleshooting motors confidently and effectively.
OBJECTIVES:

 Upon completion of the course participants will be able to:

  • Specify protection requirements for motors o Maintain electrical motors
  • Specify speed control requirements for motors
  • Understand essentials of motors and drives
  • Detail the main issues with testing of motors
  • Prevent or at least minimize motor bearing failure
  • Troubleshoot and fix faults on motors and drives
  • Interface control circuits of motors with PLC’s/DCS’s
  • Reduce downtime on electrical motors
  • Improve plant safety
  • Improve plant throughput
  • Reduce your spares usage and requirements
