Abstract
A vibration motor (1), in particular for a horology movement, the motor (1) including a rotor (2) fitted with a magnet, a stator (3) fitted with at least one coil enabling the rotation of the rotor (2) to be actuated, the rotor (2) being rotationally mobile relative to the stator (3) by oscillation between two end positions, when it is actuated by the coil, and including resilient means for returning the rotor (2) between the end positions and an intermediate locked position, when the rotor (2) is no longer actuated by the coil, the motor (1) functioning by a rotationally oscillating movement of the rotor (2) to generate each step.

A vibration motor (1), in particular for a horology movement, the motor (1) comprising:
- a rotor (2) fitted with a magnet (32);
- a stator (3) fitted with at least one coil (31) enabling the rotation of the rotor (2) to be actuated, the rotor (2) being rotationally mobile relative to the stator (3) by oscillation between two end positions, when the rotor is actuated by the coil (31);
- and
- resilient means for returning the rotor between the end positions and an intermediate locked position, when the rotor (2) is no longer actuated by the coil (31), the motor (1) functioning by a rotationally oscillating movement of the rotor (2) to generate each step.
