Title:
ROTARY SOLENOID
Document Type and Number:
WIPO Patent Application WO/2018/078848
Kind Code:
A1
Abstract:
The present invention is provided with: a magnet rotor part 2 provided with a magnet part 7 having S and N poles in the radial direction Fd of a shaft 6; and a pair of stator parts 3s, 3t which are provided either side of the magnet part 7 in the radial direction Fd, and are formed by making one end 8sp, 8tp of each of a plurality of stator core parts 8s, 8t having coils 9s, 9t fitted thereto face the magnet part 7, and connecting another end 8sj, 8tj of each of the stator core parts to a casing 4 which also serves as a yoke. A pair of end surface parts 4f, 4r of the casing 4, which are provided with bearings 5f, 5r, and which face each other, are provided with a rectangular shape Sr which satisfies the condition that the length Ls of the short sides 4rs… be not greater than ½ of the length Lm of the long sides 4rm…. Furthermore, the position of a side surface part 4p of the casing 4 which extends from at least one long side 4fm… in an orthogonal direction is set as a close position Xs which allows the magnet rotor part 2 to rotate.
