Embodiment 2
[0058] Next, refer to Figure 6 Next, an electromagnetic device related to Embodiment 2 of the present invention will be described.
[0059] The electromagnetic device consists of a figure 1 The electromagnetic device 1 shown is of almost the same construction, but the form of the second slot 17 provided in the outer leg 12 of the fixed core differs from the form of the slot in the electromagnetic device 1 . Next, the form of the second groove 17 will be mainly explained. exist Figure 6 in, with figure 1 Components and regions of the electromagnetic device having substantially the same structure and effect are denoted by the same reference numerals, and descriptions thereof will be omitted.
[0060] A protrusion 17 b is formed on the bottom surface of the second groove 17 . The protrusion 17b is formed at the center portion in the width direction of the bottom surface ( Figure 6 center portion in the vertical direction) so as to extend parallel to the groove 17. The...

The present invention relates to an electromagnet device (1) which has an approximately E-shaped fixed core (10) and a correcting coil (40). The fixed core is obtained by laminating the steel plates. The correcting coil is integrally formed by punching an approximately elliptical frame by the metal plates. The correcting coil is provided with a first straight-line segment (40a) and a second straight-line segment (40b) which are parallel with each other approximately. The outside leg (12) of the fixed core (10) is provided with a first core (15) and a second groove (17) which are parallel. The first groove is formed on the magnet pole face through causing the depression of the magnet pole face (12a), and the second groove is formed on the outer face through causing the depression of the outer face. The first groove (15) and the second groove (17) are approximately parallel. One part of the first straight-line segment (40a) is included in the first groove (15), and one part of the second straight-line segment (40b) is included in the second groove (17). The first straight-line segment (40a) and the second straight-line segment (40b) are respectively fixed to the first groove (15) and the second groove (17) of the fixed core (10) through squeezing. Thus a small electromagnet device which can be produced through a relatively simple method and an electromagnetic contactor provided with the electromagnetic device can be provided.
Description
technical field [0001] The present invention relates to an electromagnetic device mounted on a unit such as an electromagnetic contactor and an electromagnetic contactor provided with the electromagnetic device, and more particularly, to a device such as an electromagnetic device having a core provided with a correction coil. Background technique [0002] First, an example of an electromagnetic device having a core provided with a correction coil will be described. The correction coil is a coil provided in a single-phase AC electromagnet, which is used to suppress changes in electromagnetic attraction due to changes in alternating magnetic flux as well as noise and vibration. [0003] Figure 5 A and 5B are diagrams schematically showing an example of an electromagnetic device, wherein, Figure 5 A is a front view of the electromagnetic device viewed from a direction perpendicular to both the driving direction of the movable core and the arrangement direction of legs forming...
