WIPO Patent Application WO/2019/132436
Kind Code:
A1
Abstract:
The present invention relates to a high-speed solenoid. A case (10) forms the physical appearance of the present invention. At least two pairs of a first permanent magnet (14) and a second permanent magnet (14') are installed in the case (10), and a number of coils (26) corresponding to the pairs of the first permanent magnet (14) and the second permanent magnet (14') are provided in a bobbin (22) of a mover (20). Magnetic paths formed by the pairs of the first permanent magnet (14) and the second permanent magnet (14') and the coils (26) are separated from each other such that each magnetic path corresponds to each pair of the first permanent magnet (14) and the second permanent magnet (14'). Therefore, a plurality of magnetic paths are formed to operate the mover (20). The bobbin (22) is made of a synthetic resin material and has a primary coating layer (27) formed on the outer surface thereof and a secondary coating layer (27) formed on a portion in which the coils (26) are wound therearound and then exposed to the outside. The present invention has an advantage in that the mover (20) is operated at a relatively high speed.
