SMOOTHING REACTOR FOR MOTOR SMOOTH-STARTER Russian patent published in 2010 - IPC H01F21/08 H02P1/42 

FIELD: electricity.

SUBSTANCE: smoothing reactor for motor smooth starter contains a double-core magnetic system fabricated of thin-sheet cold-rolled anisotropic electrical steel, insulation cylinders, power windings, fixture elements represented by plates of a non-magnetic material installed at the butt-ends of the cores designed to be integral. The distance between the cores and their height are defined by the required reactor inductivity. The power winding wire cross section is selected subject to tolerable wire heating on starting the motor. The power winding wire is fabricated of a material with a high thermal capacity, at least - aluminium. On one of the insulation cylinders there are two power windings arranged.

EFFECT: considerable reduction of labour intensity, production prime cost and basic materials consumption.
