230 – 6-Phase SPM Motor Inverter Fault Simulation
Overview
In recent years, multiphase design has been adopted for automotive motors due to the merits of cost reduction and improvement in functions.
For example, for power supplies there are 6-phase motors with 3-phase double windings that use two inverters, having a 30 deg phase shift in electrical angle. From this, by using multiple inverters, enhanced redundancy of the in-vehicle motor system is achieved. The motor system can be stopped safely without falling to be in an uncontrollable state even if a failure occurs in a part of an inverter. However, circuit simulation is necessary to accurately evaluate safety.

In this example, a JMAG-RT model of a 6-phase SPM is loaded into a control/circuit simulator, and circuit simulation for an inverter failure is carried out.

JMAG & PSIM Users Conference 2021
This is to announce that the European JMAG distributor POWERSYS will be holding the JMAG&PSIM Users Conference 2021.
This conference will center around case studies using JMAG and PSIM, and will be held online from September 27th to October 1st, 2021.
Experts and developers in the field of electricity and power electronics will be in assembly at the conference, with those from countries outside of Europe also more than welcome to take part.
We look forward to your participation.
