New theoretical approach to the synchronous reluctance machine behavior and performance

This paper introduces and develops a new operating diagram and parameter estimator for the synchronous reluctance machine, based on the machine equivalent vector model in the synchronous reference frame. The operating diagram demonstrates the machine main performance parameters, like torque, current, voltage, frequency, power factor and current angle, behavior all together in one graph. This diagram can easily be used to describe different control strategies, possible operating conditions below and above rated speed, etc. The saturation effect is also discussed with this diagram by FEM calculations.
