Problems solved by technology

[0006] However, in conventional armatures, gaps are formed between winding frames arranged side by side. Therefore, when resin molding is performed, the winding wires may move due to the pressure of the resin and fit into the gaps, thereby causing contact with the armature iron. Case of core contact

Abstract

An armature of a linear motor is provided. The armature includes an armature core having a plurality of teeth arranged linearly and spaced at predetermined intervals, and a plurality of bobbins fitted onto adjacent teeth, each of the bobbins having flange parts, a winding being wound around the bobbin to form a coil. At least one of the flange parts of the bobbin is formed with a first protrusion and a second protrusion. An overlapped section is formed by the first and second protrusions of two adjacent bobbins contacting or overlapping with each other.

Description

technical field [0001] The disclosed embodiments relate to an armature for a linear motor, a linear motor, and a method of manufacturing the armature. Background technique [0002] Conventionally, there is a linear motor that includes: an armature; a field section in which a plurality of magnets are arranged in parallel; and an armature that is arranged to face the field section. [0003] As an example of the armature of the linear motor, there is known a structure including: an armature core in which a plurality of teeth are arranged linearly at predetermined intervals; and a plurality of bobbins in which It has a flange portion, and the winding wire is wound around the bobbin in a coil shape, and each of the plurality of bobbins is attached to the tooth portion. [0004] Furthermore, the bobbin on which the winding wire is wound in a coil shape is resin-sealed with respect to the armature core, thereby preventing winding damage and the like of the winding wire (for exampl...
