Title:
VIBRATION FORMING DEVICE
Document Type and Number:
Japanese Patent JP2000301064
Kind Code:
A
Abstract:

To obtain a vibrating motor having thin and light structure and generating strong vibration under low electric power by constituting an integrated type unit by combining a rotor and an eccentric body and also permanently magnetizing the unit by constituting the unit of a ferromagnetic material and combining the rotor to a stator.

A vibrating mechanism 3 is constituted of the stator and the rotor 5. A flat disk shaped element is used as the stator. The rotor 5 consisting of a disk 18 and a shaft is used. The disk 18 is constituted of a permanently magnetized magnetic material and formed to make a thin cylindrical fan shape of about ≤180°. An assembly of the vibrating mechanism 3 is compactly housed in a compartment of a housing since the stator and the rotor 5 have a flat disk shape cooperating together. The increase the number of a winding wires this constitution makes it possible to of the stator, thus reducing the size of a necessary permanent magnet and power consumption.
