Title:
TRANSFORMER AND TRANSFORMER UNIT AND AC INDUCTION MOTOR SYSTEM
Document Type and Number:
Japanese Patent JP2601967
Kind Code:
B2
Abstract:
PURPOSE: To exhibit energy saving effect without lowering motor efficiency.
CONSTITUTION: A transformer has secondary winding n2 all of whose magnetic fluxes cross the magnetic fluxes made by primary winding N1, and it is in such winding relation that these primary winding N1 and secondary winding n2 are depolarized, and it is constituted such that the input terminal 2 on the primary winding side and the output terminal 3 on the secondary winding are connected to each other. Moreover, these transformers are combined in three sets into a transformer unit 10, and these are combined with each other, placing the secondary winding n2 of each transformer 1 at one end, whereby these are made into three phases, and the input terminal 2 on the secondary winding side of each transformer 1 is connected to a power source 12, and the output terminal 3 on the primary side of each transformer 1 is connected to an AC induction motor 11.
