Which of these best describes the purpose of an industrial drive?

  • A.To run at the highest possible efficiency at all times
  • B.To operate at exactly its rated speed continuously
  • C.To deliver the torque and speed the process requires
  • D.To draw the smallest possible current from the supply

Answer: C

Everything else, efficiency included, is subordinate to serving the process, and a drive that saves energy while failing to make the product is worthless. Recognising that ordering is what keeps specifications sensible.
