POLARIZED ELECTROMECHANICAL CONVERTER OF BRIDGE TYPE FOR ELECTRONIC WATCH Russian patent published in 1995 - IPC

FIELD: watch making. SUBSTANCE: invention refers to stepping electric motor drives. It makes it possible to expand of application of polarized electromechanical converter of bridge type of construction of magnetic circuit thanks to increased reliability and ease of manufacture with increased stability of movement and steps within limits of one turn. Axle of converter carries rotor with poles. Magnets magnetized in opposition are positioned uniaxially to rotor. Winding with insulating frame is installed on magnetoconductive frame between plates of stator with poles. Plate is positioned on columns between magnets. Additional poles are made in plate by means of slots, equal in angular extent with poles on plates having same direction of principal and additional poles. EFFECT: increased reliability and ease of manufacture. 6 dwg
