Stator dual-excitation limited angle moment motor

Abstract

The invention belongs to the field of a limited turning corner, and concretely discloses a stator dual-excitation limited angle moment motor. The stator dual-excitation limited angle moment motor comprises a stator iron core, a rotor, a magnet and a winding, wherein the stator iron core comprises a first split stator iron core and a second split stator iron core in symmetrical arrangement; two magnets are arranged between the first split stator iron core and the second split iron core; the two magnets are arranged on the center surface passing through the rotor axial line and are symmetrical by using the rotor as a symmetry center; four pole shoes are arranged on the stator iron cores; two completely identical armature windings are symmetrically sleeved on each pole shoes. The two magnetsare arranged between the first split stator iron core and the second split stator iron core of the motor; the two magnets enables the rotor to have a stable position; when the winding on the stator iron core is electrified, under the effect of the winding, the stable position of the rotor changes a certain angle relative to the stable position given to the rotor by the two magnets, so that the limited rotating angle regulation is realized; the angle position is precisely controlled.
