  • Publication number: 20210294270
    Abstract: A horological movement includes an escapement with a magnetic system to generate magnetic force impulses, so as to sustain the oscillation of the mechanical resonator associated with the escapement. In order to make possible an effective self-starting of the assembly formed of the mechanical resonator and of the escapement during a winding of the barrel, after a stop of the horological movement due to the unwound barrel spring, the escape wheel includes teeth and the pallet assembly includes two mechanical pallet-stones arranged to receive, upon starting, at least one mechanical force impulse of the escape wheel via one of the teeth thereof, the mechanical force impulse generating a starting force torque on the pallet assembly that is transmitted to the balance of the mechanical resonator to begin an oscillation of the latter so that the assembly can operate normally after a starting phase.

  • Publication number: 20210294268
    Abstract: A horological movement including a mechanical resonator and a hybrid escapement including an escapement wheel and a pallet assembly with at least one magnetic pallet-stone formed of a magnet and associated with a mechanical banking, the escapement wheel including a periodic magnetised structure defining increasing gradients of magnetic potential energy for the magnetic pallet-stone, and protruding parts associated with the increasing gradients of magnetic potential energy. When the force torque is equal to a nominal force torque or has a value within at least an upper part of a given range of values, one of the protruding parts of the escapement wheel is subjected to at least one shock on the mechanical banking of the pallet assembly after the magnetic pallet-stone has climbed any one of the increasing gradients of magnetic potential energy, thus dissipating at least partially a kinetic energy of the escapement wheel.

  • Publication number: 20210018876
    Abstract: A timepiece movement includes a magnetic escapement formed of a magnetic escape wheel with an annular magnetized structure and a pallet fork whose shaft is formed by a ferromagnetic material. The pallet shaft exerts on the escape wheel a magnetic disturbance torque due to the fact that the annular magnetized structure exhibits an angular variation of at least one defining physical parameter thereof, such that the magnetic attraction varies as a function of the angular position of the escape wheel and has a tangential component. A magnetic compensation pin is incorporated in the timepiece movement, this magnetic compensation pin being arranged such that the second magnetic disturbance torque that it exerts on the escape wheel exhibits an angular phase shift relative to the first magnetic disturbance torque generated by the pallet shaft, so as to compensate largely for this first magnetic disturbance torque.
