Abstract
Regulating body for a wristwatch, comprising: a generator provided with a rotor and a stator with M+N coils, M being a whole number higher than, or equal to, 1; and an electronic regulating circuit having a first load impedance with an adjustable value for adjusting the current in N of said M+N coils, and therefore the rotational speed of the rotor. Only a limited number of coils is therefore used for the braking, the other coils continuing to supply the electronic regulating circuit.
Claims21
Regulating member for a wristwatch, comprising:
- a generator provided with a rotor and a stator with M+N coils, M and N being each a whole number greater than or equal to 1;
- and
- an electronic regulating circuit arranged for controlling the braking of the rotor, characterized in that the circuit is arranged for controlling the braking exerted by the M coils differently from the braking exerted by the N coils.
