Description

Technical Field

[0001] The utility model relates to the technical field of motor rotors, in particular to a magnetic steel structure which is easy to replace. Background Art

[0002] As we all know, magnetic steel generally refers to aluminum-nickel-cobalt alloy. Magnetic steel is composed of several hard and strong metals, such as iron and aluminum, nickel, cobalt, etc., and sometimes copper, niobium, and tantalum. It is used to make super-hard permanent magnetic alloys. In addition, magnetic steel is also an important component required for the operation of motors and other equipment. As a prior art of magnetic steel structure, the patent with the publication number CN220342128U disclosed by the China Patent Network, a magnetic steel structure for a motor includes a rotor, a magnetic steel, an insulating part and an injection molded part. A magnetic steel slot is provided at the end of the rotor; the magnetic steel is provided in the magnetic steel slot; the insulating part wraps the magnetic steel, and there is a gap between the insulating part and the magnetic steel slot; the injection molded part is filled in the gap between the insulating part and the magnetic steel slot. The magnetic steel structure for a motor of the utility model can reduce the temperature of the magnetic steel.

[0003] However, the prior art uses a method of fixing the magnets by filling the gap between the insulating part and the magnet slot with an injection molded part. Although this method ensures the stability of the magnets inside the magnet slot, it also makes it inconvenient to replace a single magnet when it is damaged, thus forcing the staff to replace the entire rotor, which is not conducive to reducing resource waste. For this reason, we propose a magnet structure that is easy to replace.

[0004] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art.
