ABSTRACT:
The present invention relates to a synchronous electric motor of the type comprising at least one rotor part, substantially of annular disc form, magnetized so as to present on at least one of its opposite planar surfaces at least one series of magnetic poles of alternating polarities, disposed regularly along at least one annular zone, said rotor part being mounted on a rotatable shaft, the motor additionally comprising at least one assembly of several elementary magnetic circuits of a magnetically permeable material and at least one annular electric energizing coil coupled with said assembly of magnetic circuits, each of said circuits having at least one air-gap, and all of said air-gaps being arranged for cooperating with the said magnetic poles of an annular zone of said rotor part, each of said elementary magnetic circuits comprising at least two rectangular and essentially flat pole parts, which are arranged substantially radially with respect to said shaft of the rotor.
