Although the skin effect has been widely studied over the years, many of its topics remain
unclear for most electrical engineers, including undergraduate students and fresh …

The aim of this paper is to investigate the impact of material properties on performance and
optimal geometry of high-speed drag-cup induction motor (IM). Preliminary analytical …

In the designing steps of the induction machines, reducing the power consumption level of
the induction machine is a very important issue. Winding topology is one of the most …

In this study, a new design has been developed to reduce the rotor reaction generated in
squirrel cage induction motors. In this new design, slits have been opened between the slots …

Paper presents analytical and numerical model of three-phase asynchronous squirrel cage
motor suitable for fast computation of motor steady state and transient performance …

Vector control can not be well applied directly to the starting of large-power induction motors.
The starting current is so large as to cause damage to power-conductors and the whole …

Constant demands for increasing power density and safety of drive units are very actual,
especially in the automotive applications. This is the reason why high-speed machines have …

This paper presents important aspects of dragcup induction machine (DGIM) design. Firstly,
some benefits of DGIM are outlined, which make them a potential candidate for high-speed …
