Description

Technical Field

[0001] The invention relates to the technical field of motor position magnetic ring rapid positioning, in particular to a motor position magnetic ring rapid positioning device. Background Art

[0002] In a brushless motor that uses Hall signals as position resolution signals, the Hall needs to collect signals from the position magnetic ring to resolve the position of the motor's main magnetic poles, and then control the main winding action based on the position of the main magnetic poles. There are many types of existing position magnetic rings, including position magnetic rings made by lengthening the main magnetic poles and independent position magnetic rings. The position magnetic ring made by lengthening the main magnetic poles has the advantages of having the same position angle as the main magnetic poles and a simple structure. The independent position magnetic ring has strong versatility, does not need to have too high magnetic properties, is applicable to many occasions, and is more common in conventional structures.

[0003] With respect to the above-mentioned related technologies, the applicant believes that: as the main magnetic pole is lengthened, the cost will also increase significantly, especially in the structures of some high-value magnetic materials such as neodymium iron boron. Because the position magnetic ring is installed secondary, its position relationship with the main magnetic pole is not unique. Usually, the position of the position magnetic ring is adjusted or the Hall position is adjusted, which increases the operating procedures and makes the structure relatively complicated.

[0027] The present invention provides a motor position magnetic ring rapid positioning device. Compared with the prior art, it has the following beneficial effects:

[0028] (1) The motor position magnetic ring quick positioning device is configured to sleeve the position magnetic ring body at the bottom of the shaft body through the position magnetic ring body, and the connecting component is sleeved at the middle of the outer wall of the shaft body. The movable cylinder drives the lower bearing seat and the lower connecting seat to move downward, and the lower connecting seat drives the mounting seat, the abutting seat, the rubber pad and the placement seat to move downward, and the placement seat drives the limit seat to move downward into the inner wall of the magnetic pole slot.
