Description
This book covers special machines, including switched reluctance motors, permanent magnet DC machines, permanent magnet synchronous machines, stepper motors, universal motors, hysteresis motors, axial flux ironless PM motors, and SyRM. Most literature available today only covers conventional motors and their controls with applications such as induction motors, synchronous motors, PMDC motors, servo machines, and transformers. However, trends towards more specialized motors according to exact application requirements and innovations occurred with greater control and modification. This book aims to expand on these new special machines by giving in-depth information on their operating principles, applications, and controls.
