Abstract

The electric machine (100) comprises a stator (102) comprising at least two pairs of stator teeth (110, 112, 114, 116) and a rotor (104) comprising rotor teeth (126, 128). At least one coil (118, 120, 122, 124) is wound around a stator tooth, intended to generate a magnetic flux (132, 134). The electric machine comprises at least one magnetic flux diversion piece (130) and, when the coils of the stator teeth are generating a magnetic flux, said at least one piece is intended to capture a first part (132) of the magnetic flux so that it spreads from one stator tooth (110) to the other (114) avoiding the rotor (104), while a second part (134) of the magnetic flux spreads from the same stator tooth to the other passing via the rotor teeth so as to apply a driving torque to the rotor.
