The interior permanent magnet (IPM) synchronous machines have several desirable features for automotive, tools machines and residential drive applications. When operating over a wide speed range, the main problem is to assure a proper and automatically set flux weakening. The paper presents a control structure of an IPM synchronous machine proper to be used… (More)
The paper reports design and FEM simulation comments on a fractional power three-phase induction motor with severe constraints as regards frame size and supply electric parameters. The simulation stage consists in magnetodynamic and transient analyses both in 2D and multilayer approach. The study takes into consideration different topologies (straight or… (More)
The paper presents a study concerning the influence of the excitation pole shape upon the output voltage of a hybrid synchronous generator. The analysis is based on FEM simulation and represents a step in the optimization process of an existent H.S.G.
