Реферат: The vibration device has a rotor (11) located within the stator field (36) of a stator (3) with supplied windings (7), causing it to oscillate about a fixed rest point defined by cooperating springs (25). The magnetisation direction (25) of the rotor (11) lies perpendicular to the stator field (36) along a centre plane (31) passing through the rotor axis (13). The springs (25) are attached to opposite ends of a tensioning cable (21) which is secured to the rotor (11) adjacent one end and to the vibration stage (35) at a point adjacent the other end. ADVANTAGE - Compact size and reduced operating noise.
Electrically-operated vibration device for razor or hair-cutter - has lever device between oscillation element operated via stator and vibration stage
