ABSTRACT:
An axial flux electromagnetic micromotor is described. The micromotor has a stator, a rotor which is pivotally mounted in relation to the stator about an axis of rotation, the rotor having at least one pair of magnetic poles producing in an air gap a magnetic field substantially parallel to the axis of rotation and at least one substantially planar coil situated in the air gap in such a way as to intercept a flux created by the field, this micromotor having an air gap that is solely delimited by the rotor. The micromotor can be used to drive a mechanism.
