A polyphase variable reluctance electric motor is provided which may be of the linear or rotary type. It has a stator with m windings (34, 36, 38) creating a magnetic flux in the direction of movement of the mobile core and a source (40, 42) for energizing the windings with a differential phase shift, each winding being associated with its own ferromagnetic circuit completed through the core, characterized in that the core has several ferromagnetic first blades (18) parallel to the direction of movement and each split up in the longitudinal direction into first studs (20) having a given pitch p and in that the ferromagnetic circuit of each winding includes interleaved second blades alternating with those of the core and split up into second studs (14) at the same pitch p.
