A three-phase induction motor has higher efficiency than the single-phase motor counterpart. It is possible to run a three-phase motor with a single-phase source to develop a single-phase high efficiency system. The single-phase high efficiency motor, or SHE-motor, uses capacitor banks to operate at a balanced three phase induction motor using a single phase source. Unfortunately, this design has been limited, as it can only be balanced for one load configuration at a time. This provides the system to have maximum system performance. Due to this limitation in operations, it has proven to be non-ideal in commercial applications. It is seen that conventional three-phase induction motors are more practical and better suited for field applications.
