Title:
CYLINDRICAL TYPE LINEAR MOTOR
Document Type and Number:
Japanese Patent JP3217476
Kind Code:
B2
Abstract:
PURPOSE: To reduce magnetic leakage by making the line of magnetic force generated by an armature coil flow through a first core section consisting of a tabular magnetic bodies laminated in the stroke direction of a movable shaft and a secound core section composed of a tabular magnetic bodies laminated in the circumferential direction of the movable shaft.
CONSTITUTION: Tabular magnetic bodies 27, which have circuit holes 23, through which magnetic shafts 13a, 13b can be passed, on the inside of an armature core 21 and in which the outsides are formed in the shape of an equilateral octagon 25, are laminated in the axial direction of movable shafts (PS) 13, thus forming a plurality of first core sections 29 in slots 31 at proper intervals. The first core sections 29 are brought into contact magnetically with each piece of the peripheries of the outsides of the first core sections 29, and the tabular magnetic substance 27 are laminated on the PSs 13 in the circumferential direction, thus forming second core sections 33. Armature coils 35 wound in a ring shape are inserted into the slots 31. That is, when ACs are made to flow through the armature coils 35, magnetic fields in dotted lines are generated. The magnetic fields are moved in the axial direction of the PSs 13, thus generating thrust in the azial direction by magnets mounted on the PSs 13.
