VIBRATION MOTOR

摘要

The invention relates to an electromagnetic vibration motor operating at industrial frequency, meant to drive into rotation motion with the possibility of modifying the speed independently for both rotation senses. According to the invention, the vibration motor mainly consists of a rotor (1) fixed on a support (3) by means of vertical shaft (2) and also of a stator formed of two identical vibration systems, each comprising an electromagnetic vibrator (6 and 6') acting upon an elastic ferromagnetic blade (5 and 5'), the blades (5 and 5') being provided at one end with a system of rolled blades (4 and 4'), the two vibration systems being rigidly fixed on a support (9 and 9') which may move vertically in relation to the shaft (2) of the rotor (1), on a guide (11 and 11') by means of a driving screw (12 and 12') driven by a crank (13 and 13').
