STATOR OF CONSTANT CURRENT ELECTRIC MACHINE WITH CONSTANT MAGNETS Russian patent published in 2007 - IPC H02K23/04 H02K1/17 H02K21/26 

FIELD: electro-mechanical engineering, in particular, constant current electric machines with constant magnets, possible use in electric motors and constant current generators.

SUBSTANCE: in known stator of constant current electric machine with constant magnets, containing closed magneto-conductive yoke, polar constant magnets, mounted with alternating polarity on the stator axis, and polar tips, made of magneto-soft material and positioned on constant magnets on the side of air gap, in accordance to invention, symmetrically between neighboring poles (in inter-polar space) sectors made of non-magnetic materials are mounted, on sectors on the side of air gap, inter-polar flat constant magnets are positioned, having tangential magnetization, oriented with polarity of the same name to nearby polar tips and divided by nonmagnetic gap with polar magnets and polar tips, length-wise magnets are made within limits of stator poles along the axis of machine and oriented in parallel to polar magnets and tips. Inter-polar magnets are held on sectors with possible movement in radial direction.

EFFECT: increased power due to increased working magnetic flow and increased stability of output characteristics due to possible adjustment thereof.
