Problems solved by technology

[0004] However, in the motor described above, when mounting the bobbin CB to the stator core CA, only the salient poles p1 and p2 of the stator core CA are inserted into the mounting holes, and therefore, the bobbin CB is not The installation position relative to the stator core CA is likely to change due to vibration, etc., and the end of the bobbin tends to protrude toward the radially inner position of the stator core where the rotor is to be installed. Therefore, when the bobbin is assembled When a rotor with magnets is installed on the stator core, it is easy to cause the magnets of the rotor to contact the bobbins

Embodiment approach 1

[0068] - Embodiment 1 -

[0069] according to Figure 1 to Figure 10 , to describe Embodiment 1 of the present invention, wherein, figure 1 It is an external perspective view of the motor according to Embodiment 1 of the present invention viewed from one direction (the output shaft side of the motor), figure 2 is an external perspective view of the motor according to Embodiment 1 of the present invention viewed from another direction (the side opposite to the output shaft of the motor), image 3 is a perspective view of the motor according to Embodiment 1 of the present invention with the second casing constituting a part of the casing separated and shown, Figure 4 It is an exploded perspective view of the motor according to Embodiment 1 of the present invention, Figure 5 is an explanatory plan view of the motor according to Embodiment 1 of the present invention, Figure 6 is an explanatory side view of the motor according to Embodiment 1 of the present invention, Fi...

Embodiment approach 2

[0088] - Embodiment 2 -

[0089] The motor according to Embodiment 2 of the present invention is basically the same in structure as the motor according to Embodiment 1 above. The only difference lies in the structure of the stator core. Figure 11 , Figure 12 To illustrate, among them, Figure 11 is a plan view of a stator core of a motor according to Embodiment 2 of the present invention, Figure 12 It is a perspective view of the stator of the motor in Embodiment 2 of this invention.

[0090] In this embodiment, if Figure 11 As shown, first protrusions 851 and 851 protruding inward are symmetrically formed on the inner peripheral edge of the connecting portion of the stator core with the first salient pole 81 interposed therebetween, and inside the connecting portion of the stator core First protrusions 851 , 851 protruding inward are symmetrically formed on the periphery so as to sandwich the second salient pole 82 . ,like Figure 12 As shown, the flange portions of...

Embodiment approach 3

[0093] - Embodiment 3 -

[0094] The motor according to Embodiment 3 of the present invention is basically the same in structure as the motors of Embodiment 1 and Embodiment 2 above. The only difference lies in the structure of the stator core and the bobbin. Therefore, the following will focus on the differences, according to Figure 13 to Figure 18 To illustrate, among them, Figure 13 is a plan view of a stator core of a motor according to Embodiment 3 of the present invention, Figure 14 is a perspective view of a stator core of a motor according to Embodiment 3 of the present invention, Figure 15 It is a perspective view of the bobbin of the motor according to Embodiment 3 of the present invention viewed from one direction, Figure 16 It is a perspective view of the bobbin of the motor according to Embodiment 3 of the present invention viewed from another direction, Figure 17 In the motor according to Embodiment 3 of the present invention, in the state where the bob...

Abstract

A motor may include a rotor having a magnet and a stator having a stator core and a coil. The stator core is provided with salient poles, including a predetermined salient pole, separately formed in the circumferential direction, the salient poles are protruded to an inner side and face the magnet through a gap space, and the predetermined salient pole is wound around with the coil through a coil bobbin. The stator core is provided with a connecting part which connects end parts of the salient poles. The coil bobbin is provided with a body part around which the coil is wound and an insertion hole formed in the body part and into which the predetermined salient pole is inserted. The coil bobbin and the stator core engage with the other to restrain displacement of the coil bobbin to the inner side.

Description

technical field [0001] The present invention relates to a motor in which a plurality of salient poles of a stator core are provided along the peripheral surface of a magnet, and a coil is wound around a predetermined salient pole among the salient poles. Background technique [0002] In some display devices such as measuring devices for automobiles and clocks, a pointer is attached to an output shaft of a motor. As a motor used in this display device, someone has proposed such a technical solution: Figure 28 As shown, a plurality of salient poles of the stator core CA are arranged along the circumferential direction, and bobbins CB, CB on which coils are wound are attached to two salient poles p1, p2 of these salient poles (see Patent Document 1). . In the motor described in Patent Document 1, such as Figure 28 As shown in , a mounting hole is formed on the bobbin CB where the coil is wound, and the salient pole of the stator core is inserted into the mounting hole. By in...
