The purpose of this paper is to study the design opportunities in high-speed toothless toroidal winding surface permanent magnet machine enabled by the implementation of silicon carbide-based power electronic inverters. High-speed machines designed with toothless toroidal winding configuration are beneficial to eliminating the cogging torque due to the absence of stator teeth, but the airgap flux density is reduced and inductance is small due to a large equivalent airgap. On the other hand, high-pole-count toroidal winding electric machines have the advantages of less total weight and volume than the low-pole-count machines. However, the high fundamental frequency required by the high-pole-count machine is challenging to meet with silicon-based power electronic drives because of the limited switching frequency. Silicon carbide-based devices have fast switching capability due to their MOSFET characteristics and can replace Silicon-IGBTs for high voltage applications, i.e. greater than 600 V. By using silicon carbide-based power electronic drives, the above two challenges of low inductance and high fundamental frequency requirement in high-pole-count toothless toroidal winding machines can be overcome. Research studies presented in this paper show that the implementation of silicon carbide-based drives reduces the current harmonic distortion of the high-pole-count toothless toroidal winding machine and makes it feasible for high-speed operation because low inductance and high current ripple issues can be mitigated.
