PEIC_PM_V12 - multi-phase IPM machine model
Abstract
Motor model to be used in SyR-e of the PEIC_PM_V12 machine, that is a 12-phase interior permanent magnet (IPM) electric motor available in PEIC laboratory at Politecnico di Torino, designed to validate and test multi-phase motor modeling and fault models.
