Locked-rotor analysis of a Prius 2004 IPMSM motor with Digital-Twin-Distiller

In this paper, an open-source tool, the Digital-Twin-Distiller, is used, which can encapsulate the realized FEM model into a web application as a digital twin. Many papers have proposed the cogging torque and the locked-rotor FEM calculations of the Toyota Prius 2004 motor. However, these models have minor differences, mainly in rotor topology. This paper presents a fully defined motor model and the effect of the flux barrier shape on the locked-rotor simulations. The results show that minor structural changes in the flux barrier's shape in the manufacturing tolerance range significantly affect the calculated torque.
