High efficiency motors

• These should be used for all high use new plant and equipment.
  
  

Variable speed drives

• Motor type should be checked on all new equipment - it is best to buy a machine with a VSD, rather than retrofitting at a later date.
  
  
• A feasibility study into retroffiting refurbished machines should be undertaken.
  
  

Controllers

• Where electric motors run for long time periods at low loads, motor controllers should be considered.
  
  
• New controllers should be considered with new and refurbished equipment. Fitting VSD's is perhaps most feasible for old equipment.
  
  
• Load sensing control systems should be considered for idling plant to turn plant off over a specified period.
