Steady-state Analysis for Synchronous Motor on Step Motion by State Space

In this paper, the state-variable equations of synchronous motor on step motion which are used to describe steady -state characteristics are developed by state space analysing to synchronous motor with current type converter. To select rotor linkages as state variables, the difficulty of derivation to stepping sinusoidal current is solved. These models have been developed to analyse steady - state and also dynamic characteristics conveniently. The solutions are found by computer and the steady -state characteristics of synchronous motor on step motion are simulated and analyzed by using these state space models.
