Abstract :
On the basis of FEM simulations star-delta mixed winding application in Line Start Permanent Magnet Synchronous Motors was investigated. The main goal of star-delta mixed winding in LSPMSM is current higher harmonics limitation. LSPMSM (based on the 90L-4 IM type) FEM model was built. Two stator winding types were utilized: conventional star winding (the same like in the 90L-4 IM type) and star-delta mixed winding. EMF during idle-running and influence of load torque on current higher harmonics were examined.
