Abstract
The present invention concerns a two-phase, stepping or synchronous motor. The rotor (6) includes five pairs of poles and the stator consists of two identical stator components (1,2) made from a low retentivity material, each having two stator poles (19,20) and (21,22) linked by a median part (23,24) surrounded by a winding (3,4) of a length substantially equal to the width of the opening of the stator component (1,2), the median lines (25 to 28) of said stator poles (19 to 22) being spaced apart by approximately 108.degree.. The second stator part (5) is composed of a low retentivity material for closing the magnetic circuit.
