摘要： A movable assembly used in a cylinder type linear motor is provided which can be manufactured at low cost without requiring a cutting process while preventing its magnetic characteristics from deteriorating. The movable core is constructed of a laminated yoke which is formed of a plurality of electromagnetic steel plates laminated in an axial direction of the first and second direct drive shafts. A plurality of permanent magnets 31 fixed to the laminated yoke 29 are arranged in such a manner that the polarity appearing on the outer surface of the two permanent magnet 31 opposing each other through the laminated yoke 29. The first and second direct drive shafts each have a yoke mounting portion and paired supported portions at both axial ends of the yoke mounting portion. The first and second direct drive shafts are so shaped that the cross section of the yoke mounting portion orthogonal to the axial direction is smaller than that of the supported portions. Each of the electromagnetic steel plates is made up of first and second divided electromagnetic steel plate pieces of the same shape.

摘要： A plurality of grooves 25 are formed in an outer peripheral surface of a cylindrical rubber magnet 17. The grooves 25 extend in a direction in which the cylindrical rubber magnet 17 is inserted into a yoke 3. The grooves 25 are open on both ends in the direction of insertion and are also open outwardly in a radial direction of the cylindrical rubber magnet 17. The grooves are formed at predetermined intervals in a peripheral direction of the cylindrical rubber magnet 17. When the cylindrical rubber magnet 17 is inserted into the yoke 3, an adhesive 15 gets into the grooves 25 without being pushed out of a lower end surface 21 of the cylindrical rubber magnet 17. The adhesive located between adjacent grooves also readily gets into the grooves 25. By presence of the adhesive got into the grooves 25, a necessary and sufficient amount of the adhesive can be uniformly interposed between a peripheral wall section 11 of the yoke 3 and the cylindrical rubber magnet 17.

The open angle null1 of the p magnetic salient pole sections of the first group is smaller than the open angle null2 of the p magnetic salient pole sections of the second group. Then the open angles null1 and null2 are set to satisfy the expression null2nullnull1null2nullnull(2nnull1)nulls. n is a natural number. null is an angle between virtual center lines CL1 and CL2 of two adjacent magnetic salient pole sections which extend from the center of the shaft through the center of each salient magnetic pole sections. nulls is the slot pitch of the stator core.
