The present invention relates to a synchronous electric motor of the type comprising at least one rotor part of substantially annular disc form, magnetized axially so as to present, on its opposite flat faces, a series of magnetic poles of alternate polarities, disposed regularly along an annular zone of each face, the rotor part being mounted on a rotary shaft, the motor also comprising an assembly of several elementary magnetic circuits which are insulated magnetically from one another, an annular electric energizing coil which is coupled with the said assembly of elementary magnetic circuits, each of said circuits providing an air-gap and the assembly of these air-gaps forming an annular region in which are disposed the magnetized zones of the rotor part, each of the elementary magnetic circuits having substantially flat C-configuration, being placed substantially radially with respect to said rotor shaft and having a central opening in which is placed said annular coil.

A synchronous electric motor, comprising at least one rotor part of substantially annular disc form, magnetised axially so as to present, on its opposite flat faces, a series of magnetic poles of alternate polarities, disposed regularly along an annular zone of each face, the rotor part being mounted on a rotary shaft, the motor also comprising an assembly of several elementary magnetic circuits which are isolated magnetically from one another, an annular electric energizing coil which is coupled with the said assembly of elementary magnetic circuits, each of said circuits providing an air-gap and the assembly of these air-gaps forming an annular region in which are disposed the magnetised zones of the rotor part, each of the elementary magnetic circuits having a substantially flat C-configuration, being placed substantially radially with respect to said rotor shaft and having a central opening in which is placed said annular coil, the transverse sections of each elementary magnetic circuit, considered along the path of the magnetic flux generated by said energizing coil, having a practically constant area, at least in the portions of the circuit situated in proximity to the air-gap, in the portions situated at the height of the central opening, measured from the rotor shaft, and in the portion opposite to the air-gap with respect to the central opening.
