Problems solved by technology

[0003] In the prior art, due to the particularity of the filter frequency band, the traditional robot filter generally has a complex structure, resulting in a large overall volume of the filter, making it difficult to install the filter, and being affected by vibration during work. Components are vulnerable to damage

Embodiment Construction

[0025] refer to figure 1 , figure 2 , a common mode inductor proposed by the first embodiment of the present invention, comprising: two magnetic rings 101, a skeleton 102 is arranged outside the magnetic rings, and a plurality of magnetic rings overlap in the axial direction to form a magnetic core 103; one of the magnetic cores A first winding 104 is wound on one side, and a second winding 105 is wound on the other side; an insulating sheet 106 is provided between the first winding and the second winding.

[0026] In this embodiment, the skeleton 102 is composed of two annular shells, and the magnetic ring 102 is accommodated between the two annular shells.

[0027] It should be noted that, in other embodiments of the present invention, the number of magnetic rings is not limited to two, and the number of magnetic rings can be adjusted according to actual needs to achieve the required inductive reactance.

[0028] In the present invention, the common-mode inductor adopts a...

Abstract

The invention discloses a common-mode inductor and a single-phase robot filter. The common-mode inductor comprises at least two magnetic rings, the exterior of each magnetic ring is provided with a skeleton, and the plurality of magnetic rings are overlapped in the axial direction to form a magnetic core; a first winding is wound on one side of the magnetic core, and a second winding is wound on the other side of the magnetic core; and an insulating sheet is arranged between the first winding and the second winding. According to the common-mode inductor, a plurality of same magnetic rings are respectively sleeved with a skeleton and buckled together to wind two windings to form a brand-new coil, and the problems that a traditional coil with the same performance is large in size, a varnished wire is thick and difficult to wind, and the thick varnished wire is not tight enough to wind are solved.

Description

technical field [0001] The invention relates to the field of filters, in particular to a common-mode inductor and a single-phase robot filter. Background technique [0002] The control circuit part of the industrial robot, especially the power supply of the control part and the power supply of the actuator will use components such as filters. Filter is a common electrical component, which is used to effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point, to obtain a power signal of a specific frequency, or to eliminate a power signal of a specific frequency . Robot-specific filters require excellent anti-electromagnetic interference performance to ensure precise control of industrial robots. [0003] In the prior art, due to the particularity of the filter frequency band, the traditional robot filter generally has a complex structure, resulting in a large overall volume of the filter, making it diffic...
