摘要： An injection molding machine using a linear motion type electric motor (10, 20), as a drive source, is provided, which is simple and compact in construction. The linear motion type electric motor includes a non-magnetic shaft (21) on which yokes (22) and permanent magnets (23) are alternately fitted, and an annular stator (10) having an outer tube (11) within which cores (12) and printed type coils (13-18) are alternately disposed, the shaft extending through the stator. Upon supply of three-phase alternating currect to the coils, a screw of the injection molding machine coupled to the shaft is moved in unison with the shaft to thereby perform injection operation.

摘要： A linear motor (10) comprises a field portion (20) and an armature (15) arranged in predetermined spaced relation with the field portion and adapted to linearly move along the field portion. The field portion includes a plate (21), a plurality of permanent magnets (24) arranged adjacently to each other so as to arrange different polarities alternately on the plate, and mechanical fixing units (30) for fixing the permanent magnets mechanically on the plate. The permanent magnets are thus prevented from being separated under an external force which may be applied thereto. Each mechanical fixing unit each may include a cover portion (31) to cover the exposed surfaces of the permanent magnets. The mechanical fixing units are preferably formed of a non-or slightly-magnetic material.

摘要： A permanent-magnet field rotor (10) includes a plurality of permanent magnets (18) disposed in a radial fashion, and yokes (19) disposed between each two successive permanent magnets (18) and made of a lot of sheet elements (20). The method of manufacturing the permanent-magnet field rotor comprises the step of stacking a lot of same shaped thin plate members (25) each having a plurality of sectoral york element portions (26) arranged in a radial fashion and link portions (27) each linking the outer circumferential edges of each two successive york element portions (26) to one another so as to define therebetween a permanent magnet receiving slot (29). In the state where permanent magnets (18) are inserted in the slots (29) of the stacked thin plate members (25), respectively, the stacked thin plate members (25) are firmly fixed to each other. Each of the link portions (27) of the stacked thin plate members (25) is cut out in the stacking direction by a range which is less than the width of each permanent magnet (18). From this, the yokes (19) made of sheet elements (20) are formed at the opposite sides of each permanent magnet (18) and separated from one another.

A rotor assembly (29) is rotatably supported on the brackets through bearings mounted to the brackets, respectively. The brackets and stator iron core are tightened in the axial direction thereof and firmly fixed to each other. At least two rods (31) having the same length are provided on the stator iron core. Each of the rods extends through the stator iron core in the axial direction. When the stator iron core is contracted to a predetermined length, the opposite end surfaces thereof abut against the brackets, respectively, and limit the distance between the brackets.
