Evaluation of a semi claw-pole machine with SM 2 C core

New development in material and production technology influences the design of electrical machines. This paper presents a theoretical calculation and experimental verification of a single-phase semi claw-pole machine, which core is made of Soft Magnetic Mouldable Composite - SM 2 C. In comparison with a conventional claw-pole configuration the semi-claw pole machine has a higher torque capability. This is due to a slightly increased winding arrangement.
