Economic aspects of minimising the effects of mechanical stress in induction motor stator cores

摘要: Abstract The localised flux density distribution and corresponding iron loss of stacks non-oriented, silicon free iron, induction motor stator laminations have been measured together with a finite element analysis mechanical stress caused by radial clamping. results show the value choosing an inner frame diameter large enough to avoid high compression in terms annual saving cost core or reduction conductor cross sectional area.
