Electro-Magnetic and Structural Analysis of Six-Pole Hybrid-Excited Permanent Magnet Motors

Potentials and limits of the Hybrid-Excitation Permanent-Magnet (HEPM) synchronous machine are dealt with in this paper. A six-pole is taken into consideration, both parallel series configurations analysed compared. Taking advantage rotor excitation coils, permanent magnet (PM) flux can be adjusted according to operating speed improve its performance parameters. The electro-magnetic force first harmonic complete shape. Moreover, a comparison between analytical numerical formulation has been done for current control. In particular, range extended, electro-mechanical torque power increased, as well efficiency. It will shown that reduction by using winding yields an improvement motor performance. main obtained during flux-weakening operations. paper, different topologies highlight advantages drawbacks each them, how it possible achieve higher without high saliency ratio. magnetic network introduced explain contribution flux. Furthermore, amount volume PM, copper iron internal (IPM) HEPM analysed. Actually, analysis content electro-motive even varying mechanical stress shown. Finally, verified losses represent minimum component total losses.
