  • Abstract
    High speed electric machines have been widely used in many applications nowadays and are gaining more attention. However, many special design challenges exist for HSEMs. This paper aims to discuss major challenges and design considerations for HSEMs. Four different loss components of high speed design are discussed and the methods to reduce each loss component are elaborated. Bearing options for HSEMs are compared. In addition, the rotor dynamics and thermal challenges are discussed in detail, following with some design suggestions and considerations.
