23Q110 Oriented Electrical Steel

The early application of grain-oriented silicon steel (GOSS) in motors began with traditional radial flux motors, where the stator material was replaced with GOSS to develop high-performance motors. Throughout the evolution of GOSS motor applications, the GOSS teeth + NOSS yoke configuration has demonstrated the most significant performance improvement and is the most practical to implement. This approach is likely to become the most widely adopted solution for radial flux GOSS motors in the future. However, performance prediction at the tooth-yoke junction and material compatibility remain key research challenges.

GO electrical steel is not only applied in radial flux motors but has also been studied in axial flux motors. The primary difference lies in the planar air gap of axial flux permanent magnet synchronous motors (PMSMs), where the magnetic field is distributed axially rather than radially. In the development of axial flux CRGO silicon steel motors, implementations such as GOSS teeth with NOSS yokes have been explored. Considering both cost and performance, tooth-yoke hybrid designs and yokeless stator structures are expected to become mainstream solutions for future axial flux GOSS motors.

Beyond radial and axial flux motors, researchers have also investigated GOSS applications in specialized motor types. For example, Matthew C. Gardner et al. developed a double-conical rotor PM motor using GOSS. Compared to conventional radial flux motors, this design reduces core losses and improves energy efficiency without sacrificing stator flux density. As research on GOSS motor materials and structural design matures, more specialized motors are expected to adopt grain oriented silicon steel to enhance performance.
