Training ELECTRIC MOTOR CONTROL

It  is  estimated  that electrical drives and other rotating equipment
consume about 50% of the total electrical energy consumed in the world
today.  The cost of maintaining electrical motors can be a significant
amount in the budget item of manufacturing and mining industries. This
workshop  gives  you  a  thorough  understanding of electrical motor’s
working,  maintenance  and  failure  modes  and gives you the tools to
maintain  and  troubleshoot  electrical motors. You will gain valuable
insight  into the selection of the protection necessary to ensure your
motors  are  protected  against  fault  conditions,  so  as  to ensure
reliability and long life.
You   will  gain  a  fundamental  understanding  of  the  installation
operation and troubleshooting of electric motors. Typical applications
of  electric  motors  in mining, manufacturing, materials handling and
process  control are covered in detail. You will learn the basic steps
in  specifying,  installing,  wiring  and  commissioning  motors.  The
concluding  section  of  the course gives you the fundamental tools in
troubleshooting motors confidently and effectively
