Summary

A highly efficient IPM synchronous motor used in a compressor for air conditioners, which has been developed and is now commercially produced, is presented. This IPM motor fed by an inverter is more efficient than any other type of motor at any rotational speed. There are two key factors enabling such high efficiency: one is rare-earth permanent magnets placed inside of the rotor, and the other is appropriate control of the motor current vector by the inverter.
