Abstract
A machine () for stirring a liquid food substance has: a container () delimiting a cavity () with a bottom () and a peripheral wall () for containing the liquid food substance to be stirred; an impeller () comprising an impelling member () which is configured to be rotated in the cavity (), the impeller () including an arrangement of driven magnetic elements () in the form of permanent magnets; and a motor () having an output shaft () that is magnetically coupled to the impelling member () via the container bottom () and/or peripheral wall () for driving the impelling member (), the output shaft () driving an arrangement of driving magnetic elements (') that cooperate magnetically with the driven magnetic elements () so as to drive the impeller () in rotation. One of the driven magnetic elements () is positioned to: generally face a first driving magnetic element () in a generally attraction orientation relative to said one driven magnetic element (), the first driving magnetic element () driving this one driven magnetic element () in rotation; and be off-set relative to a second driving magnetic element (′) in a generally repulsion orientation relative to the one driven magnetic element (), the second magnetic element (′) driving the one driven magnetic element () in rotation.
