Document Type and Number:
WIPO Patent Application WO/2002/091551
Kind Code:
A1
Abstract:
The miniaturization of a magnetically driving apparatus for driving a permanent magnet with the magnetic field of a solenoid coil and the generation of a strong drive power. Two air−core coils (22, 23) are arrayed linearly with their axes kept coincident so as to generate magnetic fields in opposite directions. A perforated flux converging core (21) of a ferromagnetic material is sandwiched between the air−core coils (22, 23).
