Abstract
A motorization group including power and control devices, and a motor module for watches, with a motor with a coil driving an output wheel set on an output arbor, this motor module includes main mechanical and electrical connectors to a structure or another motor module, and flat links cooperating with another motor module, each coil being electrically connected to two main connectors or to two flat links, more particularly, the flat links of the motor modules are arranged for an electrical connection, a main motor module carrying a main arbor parallel to each output arbor, electrically connected by main connectors or flat links, either to the structure, or to another motor module.
Claims14
A motorization group, comprising:
- a motor unit including a main motor module, another motor module, and at least one passive sector,
- wherein said main motor module and said another motor module each comprise:
- a receiving wheel;
- at least one motor comprising a coil and driving a gear train comprising an output wheel set on an output arbor;
- main connectors for mechanical and/or electrical connection;
- and
- flat links, said coil being electrically connected to two of said flat links or to said main connectors,
- wherein said main motor module carries a main arbor parallel to said output arbor of the main motor module, and remote from said output arbor of the main motor module,
- wherein said flat links of the main motor module and of the another motor module each comprise link means and complementary link means, said link means of the main motor module being arranged to cooperate in a link attachment, in a plane perpendicular to said output arbor of the main motor module, with said complementary link means of said another motor module,
- wherein said link means and said complementary link means of said main motor module define an opening angle of a sector extending from a main pivot axis and said main motor module is inscribed in said sector, and
- wherein said at least one passive sector has a geometry, gear train, output wheel set, main connectors and flat links, like said main motor module and said another motor module, but said passive sector is devoid of said motor, and said passive sector includes an input wheel driven by said receiving wheel of said main motor module or of said another motor module, said input wheel being arranged to drive said output wheel set of said passive sector via said gear train of said passive sector, every wheel set of the passive sector being idle.
