Design of Switched Reluctance Motor by JMAG for Automotive traction application

Yusuke Makino
Automotive Motor & Electronic Control R&D 2nd, NIDEC CORPORATION


Allow us to introduce a case study of magnetic field analysis using a simulation of an SR (Switched Reluctance) motor that does not use magnets. Nidec is already addressing the application of SR motors to traction motors for vehicles and we have progressed as far as the prototype stage. We will explain a case study that compares this motor’s JMAG analysis with performance actually recorded, and an example of reducing torque ripple that has the potential to become the source of noise vibration.
