Improved design of a novel PM disc motor by using soft magnetic composite material

Summary form only given. We present some aspects of soft magnetic composite (SMC) material application in electrical machines. The object applied in the research is an inverter fed double sided axial field permanent magnet disc motor having two stators with 36 slots each and a centred rotor with 8 skewed neodium-iron-boron permanent magnets. Although the SMC materials have low permeability and high iron loss at low frequencies they are still very attractive for manufacturing the stator cores of permanent magnet motors in general. We present not only the construction procedure improvement of the permanent magnet disc motor (PMDM), but also an improvement of the PMDM parameters, magnetic field and magnetic characteristics when SMC material is used as a magnetic material for the stator construction. The complex analysis of the electromagnetic characteristics will also be performed.
