Comparative performance analysis of a standard three-phase induction motor and an asymmetric three-phase induction motor fed from a single-phase network

• The comparisons realized are built upon experimental results, based on the two three-phase induction motors of equal power.
• The models used are of the standard or traditional type and the other modified to be supplied through a single-phase network.
• This motor comprises of a new option for driving high power loads in places where only single-phase networks are available.
• The asymmetric motor showed the be more efficient than those observed on traditional three-phase motor.

This paper aims at conducting a comparative study between a traditional three-phase squirrel cage induction motor and asymmetrical three-phase induction motor fed by single-phase voltage. For the purpose of this study, two engines with the same power were employed. During the research herein, the authors investigated the behaviour of various magnitudes for each machine. It was found that the asymmetric motor features a number of advantages over traditional motors, which makes it an excellent choice when the application requires the drive loads of high power and do not have an available three-phase supply.
