Digitalisation in electric motor systems – Part III: Catalogue of case studies

The case studies cover all major motor system applications, i.e. pump, ventilation and compressor systems.

During the collection and evaluation of the case studies, the following conclusions were made:

  1. Digitalisation is an enabler to create transparency in terms of when and how energy is being used. This is a crucial first step when it comes to the optimisation of motor systems’ operation.
  2. The potential savings vary greatly. In general, savings depend largely on the following factors:
    1. Is the information that is provided through the digital solution used to implement optimisation measures? Does this necessitate human intervention and is this intervention being followed through?
    2. What is the starting point, i.e. is the motor system already optimised to some level (e.g. use of a Variable Speed Drive)? Typically, higher savings can be achieved if the motor system is not optimised at the outset. In the case studies presented, the highest savings were achieved by simply using as much energy as is really needed.
  3. Energy savings are not always the primary driver but rather a side-effect of the optimisation. Non-energy benefits play a more decisive role (e.g. avoiding downtime, decreasing maintenance cost, increasing production efficiency, extending the lifetime of equipment).
