no. 1 approach

[0028] Hereinafter, a motor according to a first embodiment of the present invention will be described. Figure 1A It is a longitudinal sectional view showing the motor 1 according to the first embodiment of the present invention. Figure 1B It is a cross-sectional view showing the motor 1 according to the first embodiment of the present invention.

[0029] Such as Figure 1A and Figure 1B As shown, the motor 1 according to the first embodiment of the present invention is an outer rotor type motor provided with a casing. The motor 1 includes a stator 2 as a stationary member, a rotor 3 as a rotating member, a case 4 , and a shock absorber 5 . The motor 1 of the first embodiment is a radial gap type, wherein the direction of the gap K between the stator 2 and the rotor 3 is in the axial direction of the rotor 3 ( Figure 1A Up and down direction) Orthogonal radial direction ( Figure 1A left and right directions).

[0030] The stator 2 includes a stator core (not shown), a s...

no. 2 approach

[0052] In the first embodiment, the shock absorber 5 is fixed to a portion of the stator 2 that faces the rotor 3 . In contrast, as Figure 2A and Figure 2B As shown, in the electric motor 1A of the second embodiment, the shock absorber 5 is fixed to a portion of the rotor 3 that faces the stator 2 . That is, in the second embodiment, the shock absorber is not provided on the stator 2 side but is provided on the rotor 3 side and rotates together with the rotor 3 .

no. 3 approach

[0054] The electric motor 1B of the third embodiment will be described. Figure 3A It is a vertical sectional view showing a motor 1B according to a third embodiment of the present invention. Figure 3B It is a cross-sectional view showing a motor 1B according to a third embodiment of the present invention. Such as Figure 3A and 3B As shown, in the motor 1B of the third embodiment, the buffer member 5 is arranged in the gap K, specifically, in the portion of the stator 2 that faces the rotor 3 when the rotor 3 rotates, and in the portion of the rotor 3 that faces the stator 2. A position where none of the opposing parts touch. The buffer member 5 is fixed on the base 122 .

[0055] Next, a motor 101 according to a fourth embodiment of the present invention will be described. Figure 4A It is a vertical cross-sectional view showing a motor 101 according to a fourth embodiment of the present invention. Figure 4B is a diagram showing a motor 101 according to a fourth embo...

Abstract

The present invention pertains to a motor 1 or a power generator provided with: a stator 2; a rotor 3 that rotates about a rotation shaft 313 so as to be apart from the stator 2 by a space K; and a buffering member 5 located in the space K.

Description

technical field [0001] The invention relates to electric motors and generators. Background technique [0002] Generally, a motor has a stator (fixer) and a rotor (rotator) that rotates around a rotating shaft with a gap between the stator and the stator. A driving force (rotational driving force) for rotating the rotor is generated by a magnetic field generated by the stator. As the rotor rotates, the rotating shaft rotates to output a rotating force (for example, refer to Patent Document 1 below). [0003] From the standpoint of miniaturization of the motor, etc., it is preferable to reduce the gap between the stator and the rotor. However, when the rotation of the rotor deviates, for example, if the stator comes into contact with the rotor, it will cause damage, breakdown, malfunction, and the like. Therefore, in order to avoid contact between the stator and the rotor, a method such as setting a large gap between the stator and the rotor or improving the manufacturing a...
