Non-intrusive efficiency estimation of induction machines

Determining the efficiency of an in-service motor requires the motor to be decoupled from its load or the use of highly specialised equipment which is often unavailable on site. In order to assess the efficiency of an induction machine, it is subjected to numerous testing procedures established by recognised international testing standards. These procedures are considered to be time consuming, manually intensive and disruptive to the machine’s operation. Also, the efficiency of the machine quoted after these laboratory tests often does not reflect the motor’s efficiency under operating conditions. This thesis aims to address the aforementioned concerns by implementing a non-intrusive efficiency estimation technique that is applicable to induction motors in industry.
