<p>The structure of the motor is as follows: a rotor (1) of which the N magnetization axes are parallel to the rotation axis (1a) and alternatively opposite; two stators, an upper stator (b), and a lower stator (a); each stator is comprised of two coplanar polar parts interleaved one (2b, 2a) into the other (3b, 3a) and separated by a sinuous gap (4); each polar part has N/2 poles spaced by an angular interval which is double of that existing between the adjacent magnetization axes of the rotor; the magnetic link between the inner and outer polar parts of the upper and lower stators is provided by the core (6) of a coil (7). This structure provides for an optimum output. The mode of operation of the motor may be as follows, according to the different means comprised therein: bipolar stepping mode; unipolar stepping mode, or synchronous continuous mode.</p> |
