[0038] The present invention will be further described in detail below in conjunction with accompanying drawings and examples.
[0039] The design idea of the present invention is as follows: due to the low efficiency and low precision of offline dynamic balancing, online dynamic balancing has its own advantages and disadvantages. Among them, the online dynamic balancing device based on static magnetic field has certain advantages for high-precision dynamic balancing, but it adopts The mouse dragon coil winding is extremely complicated, and secondly, because of the limited electromagnetic force and limited balance ability, it is difficult to apply to high speed. In order to make the dynamic balancing device simple, easy to process, and realize high-speed, high-precision, high-efficiency on-site dynamic balancing. The invention adopts U-shaped annular iron core and corresponding boss to generate electromagnetic force whose size changes with the magnetic field and whose direct...
