Abstract :
In this paper, for a single-phase line start permanent magnet (LSPM) motor, a condition for balanced operation is analytically induced to remove a rotor current loss due to unbalanced magnetic field in steady state. To minimize stator loss as well as rotor loss, a condition of minimal stator copper loss is also introduced. Finally a design methodology using two conditions is applied to a practical single-phase LSPM motor to maximize efficiency.
