       So where do drives live 
                     in Chemical 
             Engineering Land?
      They live next to…
         – Pumps
         – Compressors
         – Fans
         – Conveyor belts
         – Crushers
         – Mills
      And many more 
        places…

       Electric Motors
       • Constant Speed:
           – A/C Squirrel-Cage 
             Induction, Synchronous 
             A/C, etc.
       • Variable Speed
           – Two-Winding, Single-
             Winding Consequent-
             Pole, etc.
